Best Water Purifier Guide in India

Which water purifier is the best in India for home use

The best water filter in India to buy for home use is without doubt an RO water purifier. RO water purifiers in India come in two versions, one the traditional wall mounted RO water purifier which is the most common type of water purifier used in India and the second better type of RO water purifier is called 'Under-Sink' RO water purifier. As explained in this page, the newer type of RO water purifier, the undersink RO water purifier is the best RO water purifier in India for home use.

Why RO type water purifier is best water purifier for home?

The reason we say that an RO water purifier is the best water purifier for home use in India is because only an RO water purifier can purify and remove dissolved chemicals in water. Some poison chemicals, like salts of Arsenic or lead, can get into tap water and these chemicals are much more dangerous than the worst virus or bacteria that can possibly get into drinking water.

The salts of Heavy Metals like Arsenic, Chromium-6, Lead, Mercury, etc. in water does not have any taste or smell and can only be detected in water by chemical analysis of water. The reason why dissolved 'Heavy Metals' in water are so dangerous, is because Heavy Metal chemicals in drinking water 'bio-accumulate' in our body, which means, that once heavy metal is absorbed by our body, our kidneys or liver or any other organ cannot get rid of it. So even though there are no immediate problems, the heavy metals in our body keeps on accumulating as more and more water is consumed daily. Finally the day will come when Heavy Metal poisoning symptoms start showing. By then it is usually too late.

Because an RO water purifier is so efficient, that it can remove Atom sized molecules from water, then it is easily removes even the smallest of virus or bacteria which are many thousand times bigger than a chemical molecule.

RO water purifier advantages and disadvantages

The main advantage of RO water purifier, as explained above, is that it can get rid of dissolved solids in water, which none of the other types of water purifiers can do. So an RO membrane removes all impurities in water: all germs and all poison chemicals, leaving only very pure water.

The main disadvantages of an RO water purifier are that it requires electricity to work and wastes a little water. Other claimed disadvantages of RO like RO water is too pure and not good for health, is simply spread by people who enjoy spreading false rumours. We have full explanation with proof that RO water purifier is the best water purifier on our page about disadvantages of RO water purifiers.

Best type or kind of water purifier available in India

As we have said before, an RO water purifier is the best kind of water purifier to have. There are two kinds or types of RO water purifiers, one, the most common type of RO water purifier in India, is the wall mounted or counter top water purifier.

The second kind or type of RO water purifier is the Undersink RO water purifiers. The undersink water purifiers are known by different names like 'under-the-counter' or 'under-the-kitchen-sink' or 'Under-Sink' water purifiers. The undersink water purifier is not very popular in India now, but they are the main types of water purifiers being sold in USA, Europe, Japan, etc. due to the fact that under-sink water purifiers are designed for the modern kitchens with built in kitchen cabinets and sink.

In India, it is only recently that we have modern kitchens in the majority of houses. But the wall-mounted or counter-top water purifiers were designed many years ago, specially for use in Indian kitchens, with no built in kitchen cabinets and sink in the kitchen. But now most kitchens have built-in kitchen cabinets and kitchen sinks, so it is high time that people started using the water purfiers designed for use in such kitchens.
