Sometimes we take the most important things for granted. I recently went to the Havells water purifier lab and was amazed how I hadn’t paid attention to the one I have at home even though I’m well aware of increasing levels of pollution and impurities. 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, what you need to keep in mind is that all water purifiers come with different technical specifications and have certain basic requirements.

Some basics first –

What is TDS? It is Total Dissolved Solids present in your water. It is composed of inorganic salts and small amounts of organic substances which are soluble in water. Safe levels of TDS for human body is under 500 PPM. Usually, groundwater (water for bore wells, tube wells) has high TDS unlike surface waters (water from rivers, lakes, reservoirs, ponds). Rain water doesn’t have any TDS and that’s why it tastes so fresh.

At my home, I have a UV based purifier because the TDS was below 200 PPM at the time of installation. Typically, you don’t need a RO based purifier if the TDS is really low. But after a bit of research, I figured that UV purifiers remove only bacteria and viruses but not other contaminants like nitrates, arsenic, fluorides, mercury etc. Also, UV filters do not reduce the amount of total dissolved solid (TDS) in the water. So, first things first is to get the water tested to decide whether one needs a UV based or a RO based purifier. And I need to get the water tested again!

In the usual reverse osmosis (RO) process, most minerals are lost while removing impurities and total dissolved solids (TDS) in many instances this leads to drop in pH of water. Water doesn’t taste different in this case. Some of the water purifiers choose to not purify 100% water, instead allow some percentage of water with TDS to mix with the RO water. This makes the water taste better but the whole purpose of purification is defeated.

However, Havells Water Purifiers have been designed to purify water through 100% RO and UV purification So how do they ensure the water tastes fine and is not deprived of minerals? To maintain healthy pH levels and for natural minerals, a special cartridge for mineral fortification has been added.

The double UV purification ensures that water is kept fresh and safe at all times even during long storage of water in purifiers. Revitalizer in these purifiers makes water biologically active, this improves hydration and easy absorption in the body.

They also have a smart user interface and ‘iProtect’, a purification monitoring system that constantly monitors the purification process and ensures safe water & healthy water.

Apart from understand this major concept on how water purification is done, I also saw some more advantages with Havells –

• Aesthetic – You have the option of buying metallic ones which go with the rest of the décor of your kitchen.
• Space saving – You have the option of buying the one which can be mounted in a corner.
• Maintenance alert – Even though they have the in house service staff in place who will call you timely for maintenance, there is a maintenance alert and cartridge life indicator on the purifier itself.
• No splash – All the models including UV Plus has a faucet which prevents splashes. And I know it makes a difference because the one I have right now splashes every time and it irritates me to no end.
• Service – The service staff is trained and are on payrolls of Havells. So, you aren’t going to get unnecessary back to back service request calls. The servicing will happen only when it’s time.
