Though some of the most visible brands currently are Eureka Forbes’ Aquaguard and Aquasure, Philips’ Intelligent Water Purifier, and HUL’s Pureit, there are several other purifiers that deserve mention. In this article we’ll take a look at the other viable options.
Zero B’s Suraksha, a tap attachment which uses resin technology, has been on the market for several years. The device is very economical and does not need electricity. However, low water pressure affects the passage of water through the device causing Suraksha to malfunction when water supply is not normal. The manufacturer, Ion Exchange, claims that the technology eliminates all disease causing bacteria and viruses. It’s worthwhile mentioning here that Suraksha is effective where TDS (total dissolved solids) levels are very low as it is not known to remove dissolved solids. An inbuilt indicator signals expiry of the cartridge. Zero-B Ultimate reverse osmosis system, Zero-B Pristine and Zero-B Suraksha Plus are other water purifiers marketed by Ion Exchange.
Turbid water with excessive iron deposits may be treated with Ferro Treat and Easy Pure, two non electrical home water purification systems developed by Zeolite India. These purifiers are based on oxidization and activated carbon filtering. The company claims that water treated by these purifiers is iron and bacteria free.
Aquadyn in Auroville, Tamil Nadu has developed a home water purification system, Fontaine Melusine®, which is claimed to be capable of converting “polluted water into water that is comparable to the one of a pure mountain spring.” The purification method is based on biofiltration and biodynamisation. The system uses a five stage process – activated carbon filtering; micro filtration; reverse osmosis; biodynamisation wherein high frequency waves are captured and infused into the water; light and sound application. This purifier does not retail at stores but those interested may enquire at the Aquadyn office. The system costs approximately Rs. 28, 000.
Whirlpool of India’s reverse osmosis based water purifiers retail under the brand name Purafresh and are available in three models, Deluxe, Elite and Platinum. The company claims that Platinum, a ‘direct-flow’ reverse osmosis purifier, which is connected to the water inlet enables the user to drink pure water straight from the faucet. All Purafresh models are reverse osmosis based and run on electricity. They cost between Rs.14, 550 to Rs.22, 950.
While it is necessary to know just how contaminated the water in your area is and the nature of contamination to determine the type of water purification method most suitable for you, how do you find out about raw water? Accurate and up to date data is not always available nor is it convenient to have water tested. Eureka Forbes has a solution in Aquaguard Total Sensa. This purifier is based on Blu-G technology, which ascertains water quality and automatically selects either UV or reverse osmosis purification as the most suitable option.
India based Kent reverse osmosis systems, which is a prominent vendor of reverse osmosis purifiers, has developed Mineral reverse osmosis technology to address the problems of mineral deficiency in reverse osmosis treated water. Mineral reverse osmosis purifier, based on the same technology, uses a combination of reverse osmosis and UV technologies to purify water without removing essential minerals.
Some of these and other less prominent brands might be worth a look because of their innovative features within particular segments. You might just find a solution to your very specific requirements.
