Here’s what you should look for while buying a water purifier in 2021

Posted on January 14, 2021

When it comes to the health of your loved ones, you need to avoid making impulsive decisions. One of the important decisions that you need to make is buying the right water purifier for your home. To make a right choice while selecting the best water purifier, you need to consider numerous factors before taking a final call. If you too are planning to buy the best water purifier for home, here are some important factors you need to consider.

Water Quality

It is important to understand the quality of your water before buying a purifier. Water quality can be easily identified by the TDS meter. A simple TDS meter carried by most sales/service staff of reputed purifier companies will determine the TDS levels in your water.

What is TDS?

TDS is Total Dissolved Solids present in your water. TDS is composed of inorganic salts & small amounts of organic substances which are dissolved in water. A safe level of TDS for human consumption is under 500 PPM. Generally, groundwater (water from bore wells, tube wells) has high TDS unlike surface water (water from rivers, lakes, reservoirs, ponds).

If your water is surface water, supplied by the municipal corporation, chances are that the TDS (dissolved impurities)is low but may contain physical, chemical and microbiological impurities like bacteria and viruses. However, if your water is groundwater supplied by tankers, there may be a higher level of dissolved impurities, altering the taste of the water and at higher levels may affect your long-term health. As a thumb rule, if the TDS is above 500 ppm, then choosing an RO water purifier may be beneficial. If the TDS is lower than 500 ppm, then a well-designed multistage UV water purifier will be effective in purifying the water. If you are getting a mix of both BMC + tanker water then universal purifier with auto mineral sensing technology will be effective.

Types of Water Purifier

There are multiple water purifiers available in the market. All water purifiers have their own USPs and all claim to give the best water quality. However, understanding the working of each water purifier technology is important in order to make the right decision. Here are some more details about the water purification technologies.

RO Water Purifier

RO water purifier removes heavy metals, Fluoride, Arsenic, and other toxic impurities from water through its semi-permeable membrane. RO purified water may taste flat because reverse osmosis also removes some essential minerals from your water. Hence it is recommended for water that has high TDS level (above 500 ppm).

Important Update by National Green Tribunal’s (NGT) on RO Purifiers

RO water purifiers have become the preferred water purifier in households today, thanks to aggressive advertising campaigns, and varying levels of TDS in water throughout the country. In response to a petition filed by an NGO called “FRIENDS” in Delhi, the NGT has ruled that in light of wastage of water by RO technology and adverse health effects of drinking water with a low TDS devoid of certain essential minerals, RO water purifiers be banned in areas where the TDS of water is below 500 mg/liter. Hence, the National Green Tribunal has directed the (MoEF) to issue a notification banning RO purifiers where total dissolved solids (TDS) in water are below 500 milligrams per liter. The matter is currently sub judice and no final legislation has yet been passed to this effect.

At Alfaa, we have always maintained that water with TDS of less than 500 mg/liter be further tested for dissolved pollutants before a RO water purifier be used, and only if it is warranted should RO be used for water with TDS under 500 mg/liter. Instead of low TDS water, UV purifiers are more environmentally friendly, while ensuring purity and safety of drinking water, without any wastage of water.
