Reverse osmosis is the key principle behind RO water purifiers. Water from higher TDS (total dissolved solids) level – that is, very hard water – is transferred to the lower TDS level through a filtering membrane. RO technology uses high pressure to push water through an extremely fine filter or membrane. The holes in this membrane are as small as .0001 microns. They remove dissolved salts along with pollutants and other physical contaminants including virus, and harmful metals, minerals, bacteria and microorganisms. Most of the RO purifiers also comprise of TDS controllers (to adjust the TDS level). The filter is kept clean by flushing the separated contaminants so they drain away.
In the quest to live healthier lives, many people have turned to water filters. Some water filters fit into pitchers to provide clean drinking water. Some filters attach to faucets and filter water as it flows out of the tap, and still others filter water as it enters a house so that all of the water in the home is filtered.

Weight and Dimensions
Power
The Bureau of Indian Standards (BIS) has specified requirements for removal/reduction ofheavy metals in IS:16240. We tested the 10 brands for presence of the following heavy metals:
Arsenic: As many as six brands – Tata Swach, Zero B, Kent, Aquaguard, Electrolux and Usha – did not meet the requirement (a maximum 0.01 mg/l).
Copper: None of the brands met the requirement set by Indian Standard (0.05 mg/l).
Mercuy: All the brands more or less met the specified requirement – minor deviations were observed in Pureit, Aquaguard and Usha.
Cadmium: Minor deviation was observed in one brand, Pureit. All other brands met the standard requirement.
Iron: All the brands met the requirements, with the exception of deviation in two brands, Whirlpool and Usha.
Lead and chromium: All brands met the requirements.
Physicochemical Parameters
As per Indian Standard, an RO system shall reduce TDS level of feed water to less than or equal to 500 mg/l.
- Al brands reduced the TDS to below the limit specified (500 mg/l) when the input level was maintained at a fixed level.
- Tata Swach scored highest on this parameter, followed by Aquaguard.
- Some brands reduced the TDS level to below 100, which is also not desirable due to their reducing the intake level of essential minerals.
The turbidity of drinking water should not be more than 5 NTU and ideally be below 1 NTU. This is a key quality indicator for a water filter/purifier.
- All the brands were able to remove turbidity to a level that makes it safe and suitable for drinking.
- Kent, Whirlpool, LG and Tata Swach could remove 100 per cent turbidity and scored highest on this parameter.
- Waste water was in the range of 62 per cent–71.4 per cent. This means the recovery of water in all brands was well above the prescribed limit of 20%.
RO and RO+UV water purifiers produce a lot of waste water during the purification process. Thus, if you pass four litres of water through an RO purifier, it will produce just about one litre of potable water. All the impurities are concentrated in the waste water and hence it is not drinkable.
Can the Waste Be Used?
a) First thing: test the TDS in the waste-water stream. If the TDS is below 1,000, you can use the water in your plants.
b) Alternately, mix some of that water with tap water to mop the house. Make sure you dilute it with tap water because if the TDS is high and you use just the RO waste to mop the floor, you may see some salt deposition after the water dries.
c) You can use the waste water to clean the sewage pipe at home or kitchen because of its saline nature..
d) You can use it to flush toilets.
All the brands gave output water with agreeable taste and odour.
pH is a measure of the acidity or alkalinity of a solution. Aqueous solutions at 25 degrees C with a pH less than 7 are considered to be acidic, while those with a pH greater than 7 are considered to be basic (alkaline). When pH level is 7.0, it is defined as neutral at 25 degrees C.
As per Indian Standard, the pH of drinking water shall be 6.5 to 8.5.
Four brands – LG, Pureit, Zero B and Tata Swach – showed slight deviation from the pH requirement for drinking water.
- All the brands were able to reduce 100 per cent residual chlorine.
The presence of bacteria and pathogenic (disease causing) organisms is a concern when considering the safety of drinking water. Pathogenic organisms can cause intestinal infections, dysentery, hepatitis, typhoid fever, cholera and other illnesses. As per the BIS requirement, the RO purifier shall inactivate/kill the selected standard challenging organism E. coli.
When E. coli exceeds the permissible level in water, consumers are advised to boil the water they use for cooking and drinking, and even for brushing teeth. As per Indian Standard, the requirement is 99.9999 percentage reduction in E. coli. We observed all tested brands for four consecutive weeks to check percantage reduction in E. coli levels.

A microorganism smaller than bacteria, the MS2 virus cannot grow or reproduce apart from in a living cell. Viruses are the smallest agents of disease, and perhaps the most problematic, because they are as minute as 0.04 u (micron). Viruses cause many common human infections and are also responsible for a bevy of rare diseases. Viruses can infect all types of life forms, from animals and plants to bacteria and archaea.
Based on the requirement specified by IS: 16240,MS2 virus was spiked in input water and the output sample was tested to check the virus-removal efficiency of purifiers.
- None of the brands we tested met the requirement of Indian Standard for removal of MS2 virus. Hence, none of these RO water filters can be said to be completely safe for drinking.

- In India, high concentrations of both organochlorine and organophosphorous pesticides have been found in surface and ground water samples. Reverse-osmosis water filters are expected to remove pesticide residues.
- We tested the 10 brands for pesticide residues. They were all able to reduce the pesticide residues and scored equally well.
