Top Hot and ambient water purifiers
Let’s start with our most expensive water purifier, and arguably the best water purifier with hot and cold features ever made.
A.O. Smith Z9
Why It’s Best
The A.O. Smith Z9 Pro is a powerful water purifier with great build quality and advanced water-saving technology. It has 8-stage purification process with dual hot water temperature settings. Plus, Silver Charged Membrane Technology is built in to prevent secondary contamination.
Although this purifier is not having cold water, still I was keen to do the trying of the hot water function. This function is letting you to choose between 45°C warm and 80°C hot only at the press of one button.
After 3 minutes, I dispensed the hot water and I found that it has reached a consistent 78°C on my kitchen thermometer. I was little bit worried that maybe the temperature can fluctuate with the continuous dispensing, so I did the testing again after filling two continuous cups of the hot water.
After the second cup, the temperature was holding steady at 76°C, which is well inside the acceptable range. I am knowing that some people may think this is slightly below than the stated 80°C, but I am preferring the consistency more over the sharp temperature spikes because of the safety reasons.
Not only the purification is great, the performance of Z9 is outstanding. Across all water sources it can handle up to 2000 ppm TDS, 15 liters per hour flow rate and retained essential minerals through MIN-TECH technology.
But this performance and advanced water-saving technology comes at a cost. Z9 is an expensive water purifier. The Advanced Recovery Technology, dual temperature settings and stainless steel hot water tank all cost a premium.
Type: RO+UV Water Purifier
Storage (Normal): Yes, 9.2 liters
Storage (Hot): Yes, 0.8 liters stainless steel
Temperature Options: Yes, 45°C and 80°C
A.O. Smith has a reputation of making great quality devices and it’s no surprise that their latest water purifier is great across the board. Z9 is fantastic in purification and water-saving.
In our purification test, Z9 removed 95% of TDS from input water and handled sources up to 2000 ppm effectively. It prevented secondary contamination, retained essential minerals and performed well in our flow rate and temperature test.Made of food-safe materials with great build quality. 10 liters total capacity, 9.2 liters normal water tank and 0.8 liters hot water tank in stainless steel.
Both temperature settings work with minimal 60 watts power consumption. Night Assist has glow light effect for nighttime use. Child lock to prevent accidental hot water dispensing.
Expensive but A.O. Smith Z9 performance and water-saving technology is top-notch by any standard.

Aquaguard Blaze Insta Hot & Ambient
Why It’s Best
Aquaguard Blaze Insta is a water purifier with instant hot water technology and dual 304-grade stainless steel tanks. The design features patented Active Copper Technology that infuses copper, magnesium and calcium as per BIS standards.
Performance is great for Blaze Insta too. It can handle 2000 ppm TDS, 15 liters per hour and water quality equivalent to being boiled for 20 minutes. Hot water pathway uses 100% copper tubing so no plastic leaching.
The three main distinguishing points of this purifier are the built-in TDS meter, through which the monitoring of water quality becomes possible, the water-saving RO technology having over 40% recovery rate, and the removable drip tray sitting on the front side of the purifier.
The purifier is carrying 10 stages of purification, and this is also including the Nanopore Long-Life Filter Technology. I have set the purifier up with our borewell source and I allowed it to run for one complete purification cycle. Same like the previous option, this purifier is very thorough and it can remove the contaminants without stripping away all those essential minerals from the water.
Instant hot water, water saving technology and copper enhancement all come together to make a great device. When you add the price to it, it’s a great value.
Type: RO+UV+Copper Purifier
Storage (Ambient): Yes, 5 liters
Storage (Hot): Yes, 0.6 liters
Temperature Options: Yes, 80°C instant hot
Unlike other purifiers on this list, Aquaguard Blaze Insta has dual stainless steel tanks for maximum durability. In our tests it handled 2000 ppm TDS, saved 60% more water than regular RO systems and delivered 80°C hot water in around 1 minute.
I took the decision to check the TDS reading at the 2-week mark, and I felt glad that I did it, because the output was still holding a consistent 38-45 TDS range. So from this I became reassured that the filters were doing their performance in an optimal way.
After one more 2 weeks I checked it again, and the readings were staying perfectly stable. A consistent mineral balance in the middle portion, and a good level of alkaline boost on the output side. Not any fluctuation was noticed by me.
The input water is reaching the fully purified stage in only a few minutes, and this is because of the faster flow rate of 24 litres per hour. This is one thing which I have seen previously only with the premium purifiers, so already I am feeling impressed.
Now actually I should not have got surprised, as the hot water function is taking a small moment for heating up the dispensed water. That thing is usual. But for my quick morning cup of tea, I was not ready to do the waiting for too long.
So I tried the dispensing directly from the hot water tap, just to see whether that would do the job. The water did come out at a steady 79°C after all.
But once one litre got dispensed, the temperature was dropping slightly.
Instead of that, I decided to do the waiting for 2 minutes before dispensing one more time. I allowed the heating element to bring the temperature back to the top, and then I dispensed another cup.
This purifier with 5.6 liter total capacity is smaller than others but makes up with superior build quality using 304-grade surgical stainless steel throughout.
Blaze Insta has UV e-boiling technology providing 99.99% purified water, RO Maxx eliminating microplastics and pesticides and a comprehensive 9-stage purification process.
800W total power consumption manages both purification and heating with smart LED indicators and child lock for hot water for safety.
At the time of launch, Blaze Insta was priced premium. But at this price, it’s a steal.

Havells Gracia Alkaline Hot, Ambient and Normal
Why It’s Best
Multiple temps, alkaline goodness, and advanced purity—meet Havells Gracia Alkaline Fab. iProtect monitoring automatically cuts off water if unsafe, so you get consistent quality.
While Gracia isn’t the most feature rich purifier, it performs well. It can handle 2000 ppm TDS, 25 liters per hour flow rate and 24×7 UV LED sanitization. Revitalizer restructures water molecules for better hydration.
It is having 9 stages of the purification in total. These are including the pre-filter, sediment filter, carbon block, RO membrane, germicidal UV column, UV LED for the tank sanitation, mineraliser, alkaline cartridge and also revitaliser. The purification stages are working fairly in optimal manner and they are able for removing the contaminants while at same time enriching the water with those essential minerals.
Unlike the single-dispense purifiers, in which you are allowed to take only ambient or hot water, here much more flexibility is there because of three temperature options.
The hot water tank is delivering the water at 80°C, the warm setting is at approximately 45°C and the ambient one is at room temperature, so even those persons who are preferring the lukewarm water for the drinking purpose, they are also getting one convenient option.
This purifier is not having the cold water function so it cannot do the chilling of water below the room temperature – some of the more costlier brands they are offering this feature – but it is easy enough only to use one separate cooling solution, so myself I did not found this as a very big drawback.
Alkaline enhancement, multiple temperature options and monitoring system makes it good value. Competitive pricing and high flow rate makes it good for larger families.
Type: RO+UV+Alkaline Purifier
Storage: Yes, 6.5 liters
Temperature Options: Yes, Hot/Warm/Ambient
Always clean, always pure—the 6.5-liter stainless steel tank resists toxins with round-the-clock sanitization. Digital touch display with LED colour temperature guides for easy control and visual feedback.
Special features include cartridge life indicators, child lock for hot water and automatic safety cut off through iProtect monitoring. Revitalizer technology increases oxygen levels and reduces Oxidation Reduction Potential for antioxidant properties.
I have used the hot water dispense which was working nicely, but because my requirement was for one full thermos flask, so I did the waiting of additional 3 minutes for allowing the tank to do the reheating before the next dispense. After this the water was perfectly hot, with the temperature which is reliably consistent and one clean, mineral-rich type taste.
One downside of this purifier is that it is not having a TDS display meter on the unit itself, so you have to use one separate TDS meter time to time for checking the output water quality.
60W base power and 500W heating element gives you hot, warm and ambient water while maintaining a daily capacity of 600 liters. But, at the time of dispensing continuous hot water for multiple cups in back-to-back manner, it is tending to take little longer for the reheating in between the cycles.
| Test Type | Test Data |
| pH Range | 8-10 |
| TDS Support | Up to 2000 ppm |
| Flow Rate | 25 L/hr |
| Storage Capacity | 6.5 liters |

AO Smith Z1 Hot+Normal UV Water Purifier
The AO Smith Z1 is coming with a UV+UF purification technology. Its temperature can be set into ambient, or warm at 45°C, or hot at 80°C, same like the previous model AO Smith Z9 Pro. The Z1 is having a large 10 litre storage capacity, which is split between a 9 litre main tank and one 0.8 litre stainless steel hot water tank. Also it is having 5 stages of purification, namely the pre-filter, then sediment filter, silver activated post carbon, UV lamp and UFSS filter which is for hot water only. Because this one is a UV-based purifier, so you must first make sure that your water source is having TDS below 200 ppm, then only the purifier will do the disinfection and filtration in effective manner.
If this is not your first water purifier, then the AO Smith Z1 could be one good option to consider, provided you are having low TDS municipal water. You are most probably already having a good idea about your local water quality, and hence you can decide by yourself whether the UV purification is sufficient for your need or not. This is because the UV+UF technology it does not reduce the TDS, and also it cannot handle heavy metals or the dissolved salts. For example, the water coming from borewell, tanker or from industrial areas, all these are having higher TDS levels, which anybody with common sense will know that it is simply not suitable for UV-only purification.
You will be noticing also that the purifier is having a slightly lower flow rate for the hot water, if we compare with the dedicated RO hot water purifiers, even though the AO Smith is claiming an overall flow rate of 30 litres per hour for normal water. And yet one more limitation is that the hot water tank of this purifier is quite small only, at 0.8 litres — something which you are not experiencing in the AO Smith Z9 Pro and also the Aquaguard Aspire Blaze.
Because the purifier it was not having any RO membrane, so the process did involve a little bit of caution while selecting the correct water source. I found that the borewell water at 450 TDS was clearly not suitable — it would have dispensed the water, but the purification quality it would get compromised — and the tanker water at 800 TDS was equally much risky. So I found that the municipal water at 120 TDS was the sweet spot, and the UV purification it was effectively eliminating 99.9% of the bacteria and viruses, to deliver safe drinking water.
Importantly though, it worked, and once I had tested the hot water function and confirmed that it is reaching a steady 78°C, then I got a genuinely useful feature for the everyday kitchen use.
| Test Type | Test Data |
| pH Range | 6-7.5 |
| TDS Support | Up to 200 ppm |
| Flow Rate | 30 L/hr |
| Storage Capacity | 9 litres Normal + 0.8 litres (Steel Hot Tank) |

Livpure Zinger RO Water Purifier
Why It’s Best
With the multi-stage RO+UV+UF purification, and one competitive price of around ₹14,990, the Livpure Zinger Copper Hot is standing as one of the best budget-friendly option which we are recommending.
It is having 6 purification stages in total. These are the Super Sediment Filter, Carbon Block Filter, RO Membrane, Copper Filter, Ultra Filtration and the In-tank UV Sterilisation. All these purification stages are working in a fairly optimal manner, and they are able to clean the various water sources upto the safe drinking level.
Unlike the countertop purifiers, which are requiring one dedicated kitchen surface space and where everything is sitting in a single unit, here in the wall-mounted design there is much more flexibility available for the user.
The storage tank is having 6.5-litre capacity, so even for a small size family of 3 to 4 members, this capacity can handle a decent amount of the daily water consumption.
Type: RO+UV+Copper+MIN Purifier
Storage: Yes, 6 liters
Temperature Options: Yes, Hot and Ambient
This purifier is not showing the real-time TDS of the output water automatically, like some of the more expensive brands are offering. But it is quite easy to test the same by using one handheld TDS meter on your own, so because of this reason I did not felt it as a very big drawback.
The dispensing options are covering the ambient water, warm water at 45°C and the hot water at 80°C. Unlike the other options, here the LED touch display is placed at the front side of the purifier, and the status indicators are clearly visible even from across the kitchen.
I have used the hot water function and it was working well, but as my first few glasses were having one slight plastic type taste coming from the new filters, so I did let it flush around 10 litres of water first before doing the regular use. After this the water became perfect, with a really clean, mineral-enriched taste and a good temperature also on the hot output.
One downside of this purifier is that it is not having one real-time purification progress indicator, so you have to depend only on the tank-full light for knowing that when the fresh purified water is available for the dispensing.
The purification performance is alright for the municipal water, borewell and the tanker sources. But when it is dealing with the very high TDS water which is above 1500 ppm, then the output is tending to have one slightly flat type taste.
| Test Type | Test Data |
| TDS Support | Up to 1000 ppm |
| Flow Rate | 15 L/ Hr |
| Storage Capacity | 6 liters |
| Water Savings | 87% |
| Purification Stages | 6 stages |

BePURE Ace Copper+
Why It’s Best
The BePURE Ace Copper+ gives you 8-stage purification at the cheapest price on our list. It has RO+UV+UF triple protection, TDS controller, and copper alkaline for health benefits.
Although it doesn’t have cold water feature like the 4G model, the Ace Copper+ excels in core purification. It can handle up to 2500 ppm TDS, 15 liters per hour and instant hot water at 80-90°C in just 1 minute.
Something which should be noted is that, unlike the previous premium options on this list, this water purifier is not having any detailed digital display or smart monitoring feature. Only a basic 3-LED indicator is there, which is showing the operational status. But otherwise, you are on your own, and you will have to keep the track of filter replacement schedules by manually, or through the customer service reminders.
Even with some safety trade-offs, its high TDS capability, big water storage, and budget price make it a smart entry-level hot water purifier.
Type: RO+UV+UF+Copper Purifier
Storage (Normal): Yes, 8 liters
Storage (Hot): Yes, 1 liter stainless steel
Temperature Options: Yes, Hot and Normal
The BePURE Ace Copper+ may be the cheapest but it doesn’t compromise on essential features. Within its 8 stages, the process incorporates a TFC RO membrane, an extra UF membrane safeguard, and a UV technology for comprehensive sterilization.
Like premium models, it has 9-liter total capacity with 8 liters for normal water and 1 liter stainless steel hot water tank. It can handle municipal, borewell and tanker water sources.
I tested the output by using our TDS meter on weekly basis, and the readings were staying stable between 45-55 TDS throughout the period. This is one thing which I have previously seen to fluctuate in the other budget purifiers, so I am already quite impressed by it.
To check how this purifier is coping up with the higher TDS water, we decided to try and connect it with a tanker water source, which was measuring 1200 TDS. As per the specifications, we allowed the purifier to run its full cycle. Then, by using a TDS meter, we checked the output reading, only to find that it had dropped down to 52 TDS. After this test, the water was cleanly purified, and more importantly, it was evenly mineralised also. Despite of not being a premium brand, the purification was thorough as well as consistent, with a good mineral balance in the output. Plus, the retractable drip tray was keeping the countertop clean during the dispensing time, so the surrounding area was staying tidy.
The Ace Copper+ has 3 LED indicators for power, purification and hot water status. Auto functions like auto shut-off, auto start and float-based cut-off makes it convenient despite the budget price.
Plus with only 60W base consumption and 250W for hot water, it’s the most energy efficient hot water system on our list. The filter is designed to last one full year without replacement, reducing maintenance cost.
If you want premium features but want to save some money, the BePURE Ace Copper+ is the way to go.

Top RO Water purifier with hot and cold option
Finally, let’s check out the hot and cold water ro purifier on this list.
BePURE 4G pH Hot and Cold
Why It’s Best
The BePURE 4G pH is a full water purifier with true hot, cold and normal water dispensing. 9 stage purification with RO+UV+UF technology, alkaline enhancement and TDS controller for customizable water quality.
Not the cheapest in this category but it’s very versatile. Handles the highest TDS level on our list at 3000 ppm, delivers alkaline water at pH 8.5 and instant hot water at 80-90°C.
When we come to the hot water performance, the purifier is delivering at 80-90°C with capacity of 2 litres per minute, which is genuinely a fast one. But the cold water, this is the place where the expectations need to be managed properly. The cold water output is sitting at 15-20°C with flow rate of only 1.5 litres per hour. Because of this reason, there is one noticeable gap between what you are expecting from a “cold” label and what actually you are getting. When we tried the cold water function during peak summer time, we felt the water was cool to touch but nowhere near to refrigerator-cold. But when it is about getting truly chilled water in summer, it is falling short of the expectation, which is something we did not face while using one dedicated water cooler.
Although requires manual operation for hot water function, the features are comprehensive. True three temperature function, alkaline enhancement and extreme TDS handling, and the price makes it a good buy.
Type: RO+UV+UF+Alkaline Purifier
Storage (Total): Yes, 9 liters
Temperature Options: Yes, Hot/Cold/Normal
Same like the BePure Ace, this Bepure 4G is also having only a basic LED display that is showing the operational status. So while you are checking the filter life and maintenance alerts, it is tending to show only limited information, and this can become little inconvenient when you compare with the detailed smart interfaces of Havells and Aquaguard.
The BePURE 4G pH is a big leap in water purification technology, with great results across all temperature functions. 15 liters per hour flow rate, extreme TDS handling and true hot and cold water options.
I connected this purifier to borewell source having 530 TDS and allowed the purification cycle to complete fully. The output water was tested at 55 TDS, which is coming within the acceptable range. After that I tested the hot water by dispensing it directly into one measuring flask with a thermometer inside. After few attempts of getting the correct dispensing rhythm, the hot water was coming out at a consistent 82°C, which was impressive for this price range only.
Following the manufacturer’s specification, I manually tested the cold water output also. In just under 20 minutes, the cold water had reached 18°C. I was pleasantly surprised with this cooling capability at such a price point, specially because I was not expecting a budget purifier to cool the water even up to this degree, and overall it is offering a decent value for money.
Finally I tested the normal water dispensing part. I am a regular user of ambient purified water, however whenever I have used budget purifiers earlier, the taste was sometimes having a plastic-like note which can be off-putting for many people.
I dispensed one full glass of ambient water and tested it for taste and also clarity. The alkaline mineralisation was adding a noticeably smoother mouthfeel when compared to the basic RO water.
Has separate storage tanks with 1 liter for hot water in stainless steel, 1 liter for cold water and 7 liters for normal water in food-grade plastic. Alkaline mineralisation adds calcium, magnesium, potassium and copper while maintaining pH at 8.5.
Comes with smart LED indicators for water tank status, purification progress and temperature function activity. TDS controller allows adjustment to ideal levels between 50-150 ppm.
Consumes 500W when hot/cold functions are active, 60W when base purification is active.

How We Tested?
For making this list of best hot and cold water purifiers, at first we have analyzed the physical parameters such as the storage capacity, the tank material, build quality, dimensions and also the installation flexibility. After that, we tried for dispensing the water in different temperature settings, and we checked that how accurately the purifier is maintaining the set temperatures which we selected. We also checked that how nicely the purifier is able to filter the water, by noting the aspects like the TDS reduction, the flow rate, taste of the purified water, and whether the mineral balance is getting retained or not, the consistency in the purification and many more things. Furthermore, we have used each of the appliance for many weeks inside a regular Indian kitchen, so that we can know more about the positive points and also the challenges which a user is facing in the day-to-day usage.
How To Choose A Hot and Cold Water Purifier?
Here are given below the most important factors which you have to think about carefully before selecting a hot and cold water purifier for your home.
Purification Technology
The purification technology is the very first and most important thing that you must consider whenever you are going to buy any water purifier. An RO type water purifier become compulsory in case your water source is having TDS more than 200 ppm. The RO membrane is doing the effective work of removing the dissolved salts, heavy metals, pesticides and also the chemical contaminants from the water. On other side, the UV (Ultraviolet) purification is giving one extra disinfection layer which is killing the bacteria and viruses, but without doing any change in the water chemistry.
The brands like AO Smith and Aquaguard are also giving the multi-stage purification along with their SCMT and Nanopore technologies. These are having some additional filtration stages also, which is doing very effective job for handling the secondary microbial contamination and some specific industrial pollutants too.
But if your water is coming from a municipal source only, where the TDS is staying below 200 ppm, then in that case a UV+UF purifier such as the AO Smith Z1 will be more than enough for fulfilling all your requirements.
Storage Capacity
Almost each and every hot water purifier is coming with one storage tank which is having the range from 6 to 10 litres. But here you must remember that the hot water tank capacity is playing very important role for deciding how much quantity of hot water you can take out at one single time. When the hot water tank is smaller in size, then you have to wait for more longer time in between the two dispensing cycles. Because of this the hot water is finishing very fast if you are serving many cups one after another back-to-back. So as a result of this, there is more chances of waiting time coming in between the uses.
In ideal condition, one family of 3-4 members should always search for minimum 6 litre of total storage and also one separate dedicated hot water tank of 1 litre or above, so that they can take out the hot water without facing the frequent interruptions again and again.
Hot and Cold Water Features
The hot and cold water dispensing is one convenience type feature which is varying a lot from one model to another model. Mostly all the purifiers in this list are giving the hot water at 80°C temperature. Some of them like the Havells Gracia FAB is giving also one warm water option at 45°C. But the truly cold water dispensing is very much limited only. The Bepure 4G pH Black is offering only mild cold water around 15-20°C, which is more cooler than the normal room temperature but still it is not that much cold like the refrigerator one. So before doing the buying, you should first decide properly whether you are genuinely needing the cold water or the ambient temperature water is only sufficient for you. And one more thing, if the purifier is having the hot water function inside it, then most probably it will be having the child lock also. The Bepure 4G pH Black, even though it is a budget category purifier, still it is providing the child lock protection to the users.
TDS Handling Range
TDS handling range is one very important factor which you must consider, specially when your water source is keep changing. In ideal way, you should firstly know the TDS level of your water supply, before you go to choose any purifier. Most of the RO purifiers are handling up to 2000 ppm TDS in effective manner, and this is covering the maximum of Indian water sources like borewell, municipal and also tanker water.
The budget options such as Bepure 4G pH Black and BePure Ace, they are capable to handle up to 3000 ppm TDS. One more important aspect which comes here is the consistency, means how the purifier is keeping the output TDS in low level as the filters are becoming old.
Almost all the RO purifiers are doing effective job in reducing the TDS. Because the RO membrane and the filters are the heart components, so you will not face much trouble regarding the purification quality in starting period. Most of them are also having the filter life indicators. But still, we are recommending you strongly against to extend the filter usage more than the recommended schedule, because the purification quality can drop in very significant manner and it may create the health risks also.
Installation and Footprint
In these days, mostly all the water purifiers can be either wall-mounted or you can keep them on the countertop. The wall-mounted type installation is saving the countertop space, and also it is keeping the purifier at one convenient height for the dispensing purpose. Generally they are requiring the professional installation, which comes at some additional cost. The budget friendlier options like Bepure, they are charging ₹500 in separate manner only for the installation. Whereas the premium brands like AO Smith and Aquaguard, they are mostly including the installation inside the purchase itself. So if the convenience is mattering for you, then you should go for such brand which is offering the complimentary installation.
Build Quality and Tank Material
The stainless steel tanks, they are considered as the gold standard for the water purifiers, and specially for those ones which are having the hot water functions. The reason is that the heat is not degrading the stainless steel in the same way like it can affect the plastic over the period of time. The AO Smith Z9 Pro, Aquaguard Aspire Blaze and also Havells Gracia FAB, all of these are using the stainless steel tanks. But the budget options like Bepure, they are using the food-grade plastic, which is although safe to use, but it may not be that much durable for the hot water storage in the long term period.
Price and Maintenance Cost
The starting price of hot and cold water purifiers, it begins from Rs. 12,000 and goes upward. The costlier models, they are having better build quality with advanced purification and also stainless steel tank inside, but the budget one mostly not having these things. One more thing, the yearly maintenance cost is differing very much from model to model. Budget purifier such as BePure Ace is having annual filter cost near about ₹2500 only, but the premium brands, they can charge somewhere between ₹4000 to ₹6000 for one year maintenance. If you want to control this expense, you can take annual maintenance contract directly from the brand itself. This one, mostly it comes cheaper compare to paying for each service visit separately.
Safety Features
Every water purifier, it should be having some basic safety features, like child lock for the hot water, auto shut-off when tank becomes full, filter change indicator and also purification alert. Good thing is, most of the water purifiers in India are already coming with these basic safeties.
But some advanced option, like Havells Gracia FAB, it is going one step more ahead with iProtect purification monitoring, which is cutting off the water supply itself if the purification quality is dropping below the safe level.
After-Sales Service
For the people who are new in this hot water purifier line, it is better to choose the brands like AO Smith or Aquaguard, because they are having very wide service network all over India, or you can also see option like Havells which is giving detailed smart alert for the maintenance scheduling. Otherwise, you should look for such brands who are giving responsive customer support and also easy availability of the replacement filters. Only depending on the first installation, it may not be enough for the long-term trouble-free working.
Purification Performance Comparison
All water purifiers performed well. Whether it was removing contaminants from different water sources or high TDS levels, all the purifiers on this list did great with varying capacities.
TDS was not an issue for most of these water purifiers. Only the Livpure Victor had input above 2000 ppm which is 15% more than the average. BePURE 4G pH was the best in TDS handling with 3000 ppm.
Livpure Victor struggled with only 1000 ppm capacity which is 50% less than most others. Havells Gracia had the highest flow rate at 25 L/hr.
In all other tests, the water purifiers we selected were almost perfect. Bacterial and viral contamination was not an issue, mineral retention was maintained and even microplastics were removed.
Temperature Control Comparison
In the temperature control test, we test the performance of each purifier in hot and cold water operations. Purifiers that have shorter heating times and can use real cold water are rated higher in our overall testing.
To test this we time how long it takes to heat water to set temperatures and cheque the uniformity of temperature delivery over many uses.
| Purifier | Hot Water Temp | Cold Water Temp | Heating Time |
| A.O. Smith Z9 | 45°C & 80°C Dual | Not Available | < 3 minutes |
| BePURE 4G pH | 80-90°C | 15-20°C | 30 sec – 5 min |
| Aquaguard Blaze | 80°C | Not Available | ~1 minute |
| Havells Gracia | Hot/Warm/Ambient | Not Available | Not specified |
| Livpure Victor | Instant Hot | Not Available | 15-20 minutes |
| BePURE Ace | 80-90°C | Not Available | 1 minute |
The majority of purifiers included in this list have hot water capabilities, and only the BePURE 4G pH has real cold water dispensing. But at 15-20 0C this is not really chilled water but mild cooling.
Storage Capacity Comparison
In order to cheque storage capacity, we cheque total volume, cheque tank materials on durability, and cheque on separate compartments. Higher capacities that are stainless steel constructed are more valuable and hygienic.
A.O. Smith Z9 had the highest total capacity of 10 litres and the Aquaguard Blaze had the lowest capacity of 5.6 litres. Hot water tanks were 0.8 litres on average and were made of stainless steel to ensure higher heat retention.
To recap it all, the Aquaguard Blaze has two stainless steel tanks, one with hot and the other with ambient water, which is much more durable despite having a lower capacity.
Power Consumption Comparison
To measure power use, we keep track of electricity use in purification, heating, and standby. A power metre records the data of each mode.
The standby consumption of all purifiers with given data was similar at about 40W. At 250W, the BePURE Ace was the most efficient hot water system, 40 percent better than the average.
Water Enhancement Comparison
No one-size-fits-all: purifiers provide a broad range of improvements, such as remineralization, pH optimization, copper dosing, and so on, each addressing different user requirements.
The table below indicates the enhancement features and health benefits that come with each purifier. Remember that there are various types of purifiers, which can be enhanced in various ways.
Maintenance Comparison
Water purifier maintenance covers philtre replacement, cleaning and maintenance fees. The estimated annual costs are based on the life of philtres, replacement and service plan options.
| Purifier | Filter Life | Estimated Annual Cost | Service Benefits |
| A.O. Smith Z9 | 6000 L (12000 L for 2X model) | ₹5,500-6,000 | Standard warranty |
| BePURE 4G pH | 6000 L | ₹2,500-3,500 | Annual replacement |
| Aquaguard Blaze | 6000 L | ₹5,200-6,000 | Standard warranty |
| Havells Gracia | 6000 L | ₹3,000-4,000 | Standard warranty |
| Livpure Victor | 6000 L | ₹0 (30 months), 5,400 – 6,000 | 30 months free service |
| BePURE Ace | 6000 L | ₹2,000-3,000 | Annual replacement |
| Average | 6000 L/year | ₹5,000-6,000 | Varies |
The most interesting exception to this list is the Livpure Victor, which comes with 30 months of free service and maintenance. This saves more than two years of annual expenses, which makes a big difference in the overall cost of ownership.
