How do you choose home water purifiers? Based on brand? Based on price? Based on what you heard about it from your neighbors, friends, or relatives? Or based on any other factor? If you answered ‘yes' to any of these questions, I am sorry to say, you are completely wrong. When it comes to water purifiers, none of the things I have mentioned above matters. What matters is - the technology it is based on.

Yes, I will say it again. If you are going to buy a water filter, the only thing you should look out for is the technology it is based on. The reason is both obvious and simple. Why do you use home water purifiers? To get pure water to drink and to use for other purposes, right? If that is the case, shouldn't you look out for the best technology that can give you pure water? Factors like brand, popularity, and price should take second place

 In order to find out the best water purification technology, you need to compare home water purifiers. So, let us take a look at the three most popular technologies today - reverse osmosis, point of use distillation, and active carbon filtration.

Reverse osmosis - In this method, water is passed through a semi permeable membrane under pressure and any substance that is larger than water molecule is blocked. There are two major disadvantages with this method. One - it cannot remove any contaminant that is smaller in size than water molecules. Two - it tends to destroy the essential minerals present in water. Also, it is pretty expensive. When you compare home water purifiers, you can easily find out that there are far cheaper alternatives available in the market today.

 Point of use distillation - In this method, water is passed through a very hot coil and converted into water vapor. Then it is passed through a cooling chamber and converted into water again. There are two major disadvantages with this method too. One - it is not capable of removing the organic contaminants present in water. Two - like reverse osmosis, it also tends to destroy the essential minerals present in water.

 Active carbon filtration - this is actually a three in one method. It involves active carbon filtration, ion exchange, and sub micron filtration. Unlike the other two methods, this does not have any major disadvantages. It tends to remove all sorts of contaminants present in water and it retains the essential minerals that are good for the body. Most importantly, this is the cheapest of all three methods.

 When you compare home water purifiers, you can easily find out that the combination of active carbon filtration, ion exchange, and sub micron filtration is the best technology by miles. This is also the reason why physicians suggest using water purifiers based on this technology.

 So, you now know how to choose home water purifiers. Now, put your knowledge to good use and go get a good water purifier today. Enjoy the benefit of pure water for years to come.
