Water purifiers have become an absolute necessity in any home in the current scenario. With growing concerns over contamination, it is no more a luxury as it used to be two decades back. 

There are many variants of water purifiers available in the market depending on the manufacturer. Some come cheap and perform the most basic task of purifying the water while others are on the costlier side that comes with added features like adding minerals into the purified water or adding an extra layer of filtration to give added assurance to the users. 

Depending on your preference, all water purifiers fall largely under these three major variants; Reverse Osmosis, Ultra Violet, and Gravity based purifiers. While we are all familiar with the water purifiers that are wall-mounted or a table-top, there is another variant called the under sink water purifiers. This particular variant isn’t as popular as its other counterparts. 

Nevertheless, it does exactly what the more common and popular variants of water purifiers do. The only difference here is that this appliance is installed under the sink. Hence, the name “under sink” purifier. In the case of this particular purifier, it also comes in three major variants; Reverse Osmosis, Ultra Violet, and Gravity Based. In this article, we will discuss in detail particularly under the sink “reverse osmosis” water purifiers. Here we go.

What Is An Under Sink Ro Water Purifier & How Does It Work?

An under sink RO water purifier is a type of water purifier that is fitted in the bottom of the sink. It is directly attached to the pipeline through which the water flows. Like any other water purifier, under sink RO water purifiers are equipped with various water purification processes to remove impurities from the water. This purified water comes through the attached tap from which can be drunk directly. 

The main highlight of this particular water purifier is that it uses the process of reverse osmosis, more commonly known as RO to purify the water. RO works by using a partially permeable membrane that separates ions, unwanted molecules and other larger particles from the water. This process separates dissolved and suspended chemicals and biological elements like bacteria from the water.

 With the advancement of technology, many water purifiers have added features to make the water better in terms of nutrient content in addition to the removal of impurities. Undersink water purifiers have a high rate of water flow as a result of the hydrostatic tank attached to the purifiers. This allows the water purifier to fill containers much faster than the wall-mounted counterparts.
