Increasing water pollution levels is a growing concern, especially since it has now hit home for many people. The availability of clean and safe drinking water is a rare privilege. Therefore, it is crucial to ensure that the drinking water at home is always free of harmful substances. Otherwise, it can lead to several health problems, such as water-borne diseases and infection. A solution to avoid this is to have a water purifier at home. Water purifier – What it is A water purifier works nearly the same as water filters but has some added advantages. Regarding similarities, water purifiers and filters remove impurities from drinking water. Besides this, a water purifier goes a few more steps ahead by removing harmful minerals from water and killing off all biological impurities. Most water purifiers do this using two methods: Reverse osmosis This method works similarly to the normal filtration process. However, it does not use a device to capture all the impurities and pollutants. Instead, the RO process involves using a small, semi-permeable layer through which water is forced to go. Because of the high pressure of the force, particulate matter, impurities, and contaminants present in the water are captured in the membrane.
