Summary: As there are too many brands and variants of water purifiers available in the market, it confuses the prospective buyers, especially the first-timers. The following post helps in getting answers to some commonly asked questions.
With the water quality depleting day by day, water purifiers have become a must-have appliance if you want to avoid buying bottled water. The market is flooded with different brands and variants of purifiers, each claiming to be the best water purifier. The different purifiers use different technologies and the price variation is huge. It often confuses the consumer as to which the best water purifier for home is as they are often ignorant about the quality of water reaching their home and which technology is best for what quality of water.
Here are some common queries answered regarding these purifiers, which can help you make an informed choice.
What Are the Different Types of Technologies Available for Purifying Water?
The most commonly used technologies are Chlorination, Boiling, UV (Ultra Violet), UF (Ultrafiltration) and RO (Reverse Osmosis) Purification.
Which Is the Best Water Purification Technology?
The effectiveness of the purification technology is dependent on the quality of water reaching your area. The contaminants present in the water can be broadly classified as physical, biological and chemical. If there are only physical contaminants present, then boiling water and using simple filtration is enough. The biological contaminants require the use of UV filter. In case the water has more of dissolved chemical salts in it, then nothing but an RO purifier is recommended. At times, the water contains a mix of different contaminants and then a person needs a purifier that makes use of several layers of filtration using a combination of technologies like RO+UF+UV and so on.
Which Is Better: UV Filtration or RO?
If we see technology-wise, then no doubt RO is a superior technology where the water is passed through a semi-permeable membrane. This membrane has pores of size 0.0001 microns, which lets the water molecules to pass through it, but the contaminant chemicals salts being bigger in size are held back.
In UV purifier, the UV rays penetrate through the cells of the microbes that are present in water and hence destroy their ability to reproduce. This technology is very effective on harmful microorganisms rendering 99% of them inactivate but is of no use on chemical contaminants.
Thus, depending on the type of contaminants present in the water reaching your home, you should make a choice.
Is RO Better than Buying Bottled Water?
The technology used in the bottling plants of the branded bottled water is the same as the one used in an RO purifier. The difference lies in the fact that having RO purifier at home can get you more fresh water, unlike the bottled water where the filtration might be done days ago and the water is let to sit in the plastic bottles for weeks or months before it is consumed. The improper handling of these bottles can again pose health risks. Also, the bottled water costs much more than filtering it at home using an RO purifier and you can also do your bit for the environment as ultimately these plastic bottles end up in a landfill.
