A UV-UF water purifier is an apt choice for homes that get water with a low TDS of less than 200 ppm. The Ultrafiltration (UF) membrane captures harmful germs, heavy metals and other contaminants in the water, while UV kills bacteria, viruses and other germs. This set-up is usually sufficient for municipality water and surface level water sources. An RO water purifier on the other hand is necessary only if the TDS level is higher than 500. This is because the UF membrane is not capable of removing dissolved salts from the water.
So, let us look at some of the top UV-UF water purifiers available in the market. They are available at a price less than around Rs. 11000.
Best UV-UF Water Purifiers In India
KENT Maxx 7-Litres Wall Mountable/Table Top UV + UF (White and Blue) 60-Ltr/hr Water Purifier
Kent Maxx water purifier is an elegant and compact option suitable for homes that have municipal water supply.

The machine can purify upto 60 litres of water per hour. It also has a 7 litre storage tank that keeps the water safe and clean. Further, the water tank is detachable. So, it is easy to clean the tank regularly to ensure that you get safe and pure water at all times.
The water purifier also has indicators to alert when the UF membrane needs to be changed or if the UV lamp fails.
Kent Ultra Storage 7 Ltr, UV and UF Water Purifier
Similar to the previous option, Kent Ultra is yet another compact water purifier that is best suited for wall mounting.
It too has a UV chamber with 11 watt lamp that effectively kills bacteria, viruses, cysts and other pathogens. Then, the water passes through a UF membrane that can capture all [articles smaller than .01 to .1 micron in size. This captures all contaminants like heavy metals, deactivated pathogens etc.
The storage capacity of the tank is 7 litres. It can filter up to 60 litres of water per hour.
Just like the previous option, the water purifier has indicators for UV failure and when the membrane needs to be changed. Also, as a fail safe, the water purifier doesn’t operate when the UV lamp malfunctions. So, you can always be assured that your water is pure and uncontaminated.
The purifier needs a minimum water pressure to work effectively. If not, you may have to install an additional water pump to increase the inlet pressure.
AO Smith X2 5 L UV Ultra Violet + UF Water Purifier
AO Smith is one of the upcoming contenders in the water purifier segment. They introduced the first water purifier that provides hot water.
Compared to the previous options from Kent, the AO Smith water purifier is a bit more expensive. But, it has more filters and hence has a better water purification system.
The water first passes through two stages of sediment filters to capture sand, debris and other larger particles. This helps improve the life of the UF filter. Then, the water passes through a carbon block to get rid of any odour. In the next stage, the water passes through a UV lamp to kill any bacteria, virus and pathogens. In the final stage, it passes through the UF membrane to capture the killed pathogens, heavy metals and other suspended solid particles.
As it has more purification stages, the purification process takes a longer time. The unit can supply just 30 litres of water per hour, while the previous options from Kent purifies 60 litres per hour. Its storage tank is also a tad smaller with just 5 litre capacity.
Just like Kent, AO Smith X2 also needs an input pressure of 25 psi. Or else, you may have to install an external water pump.
Eureka Forbes Aquaguard Aura 7L water purifier
Eureka Forbes Aquaguard Aura is an excellent water purifier that offers multiple stages of filtration to purify water perfectly. Further, it adds minerals and imparts the goodness of copper to provide the best water for your health. But note that this water purifier is an apt option only if the TDS level of the input water is less than 200.
The water purifier looks quite elegant in black and copper finish. It can be wall mounted or kept on top of the countertop.
The purifier passes water through 6 stages. In the first stage, it passes through a sediment filter to capture dust, dirt and sand from the water. Then, it captures chlorine, organic impurities and other bad odour from the water.
In the third stage, the UF filter captures any suspended solids like heavy metal, germs and pathogens. Following this, the Mineral Guard filter imparts calcium and magnesium to the water. In the fifth stage, water passes through the UV chamber so that any harmful bacteria, virus or cyst is eradicated. In the final sixth stage, water passes through a copper chamber so that water gets infused with copper ions. As per Ayurveda copper infused water is quite beneficial for healing thyroid imbalance, indigestion, arthritis, anaemia etc.
The water purifier has a 7 litre storage tank. Its filters last for purifying 6000 litres of water. But a drawback is that complete filter change costs about Rs. 4-5K.
