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.
| Category | A.O. Smith Z9 | BePURE 4G pH | Aquaguard Blaze | Havells Gracia | Livpure Victor | BePURE Ace | Average |
| Overall Purification Score | 98% | 96% | 97% | 95% | 93% | 94% | 95.5% |
| TDS Input Range | 2000 ppm | 3000 ppm | 2000 ppm | 2000 ppm | 1000 ppm | 2500 ppm | 2083 ppm |
| Flow Rate | 15 L/hr | 15 L/hr | 15 L/hr | 25 L/hr | 1.8 L/min | 15 L/hr | 16.5 L/hr |
| Purification Stages | 8 | 9 | 9 | 7-9 | 8 | 8 | 8.3 |
| TDS Reduction | 95% | Adjustable | 95%+ | 95%+ | 95%+ | Adjustable | 95%+ |
| UV Protection | Yes | Yes | Yes | Yes | Yes | Yes | 100% |
| RO Membrane | Yes | Yes | Yes | Yes | Yes | Yes | 100% |
| Water Recovery | 2X savings | Standard | 60% more | Standard | 87% more | Standard | Varies |
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.
| Purifier | Total Capacity | Normal Tank | Hot Tank | Cold Tank | Tank Material |
| A.O. Smith Z9 | 10 L | 9.2 L | 0.8 L SS | N/A | Food Grade ABS + SS |
| BePURE 4G pH | 9 L | 7 L | 1 L SS | 1 L | Food Grade + SS |
| Aquaguard Blaze | 5.6 L | 5 L | 0.6 L | N/A | 304 Grade SS |
| Havells Gracia | 6.5 L | Combined | Combined | N/A | SS + Food Grade |
| Livpure Victor | 6 L | Combined | Combined | N/A | Plastic |
| BePURE Ace | 9 L | 8 L | 1 L SS | N/A | Food Grade + SS |
| Average | 7.6 L | 7.3 L | 0.8 L | N/A | Mixed |
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.
| Purifier | Ambient Power | Base Power | Hot Power | Cold Power | Max Power | Energy Mode |
| A.O. Smith Z9 | 40W | 60W | Included | N/A | 60W | Yes |
| BePURE 4G pH | 40W | 60W | 500W | 500W | 560W | No |
| Aquaguard Blaze | 40W | N/S | N/S | N/A | 800W | Yes |
| Havells Gracia | 40W | 60W | 500W | N/A | 560W | No |
| Livpure Victor | 40W | N/S | N/S | N/A | N/S | No |
| BePURE Ace | 40W | 60W | 250W | N/A | 310W | No |
| Average | 40W | 60W | 416W | N/A | 476W | 33% |
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.
