Water from any organic source is generally heavily contaminated. Wells, rivers, or reservoirs-drinking water directly, without filtering it into a water purifier, may cause many ailments. Tap water, that can be reportedly treated before reaching you, is discovered to possess lots of contaminants. Therefore it becomes imperative that you use a reliable and reputed water purifier to purify the water that you have.
Water heaters in India, come in a range of brands and types, each one claiming to be the best. Before you settle for a water purifier though, it is essential to understand what type of filtering systems they supply and also how effective each is. Only then can you make an educated decision before buying.
Water heaters are generally classified into five basic kinds.
Distillation Type – These water heaters distill water i.e. water is allowed to boil and vapors are collected to give you pure drinking water. This process effectively eliminates contaminants, sediments and germs. The drawback of these water filters is it is very slow and gives roughly only one liter to each ten liters filtered. Additionally, the purification procedure doesn’t allow oxygen to pass through, thereby reducing the quality of water.
Activated Carbon Type – These types of water filters use carbon particles to wash water. The contaminants and sediments in water adhere to carbon surfaces, and you get clean water. It also effectively eliminates any odor that may be present. The drawback of this filter is that it can’t kill the microorganisms within the water.

Backwash kind – Water is passed through a purifying medium, which traps sediments, residue and contaminants. Many kinds of purifying cartridges are available on the market. The drawback of this type is again, that it does not kill germs that are harmful.
Reverse Osmosis purifiers – RO as it is called, was initially developed to desalinate seawater. Water is passed through a semi permeable membrane in order that only single molecules can pass through. This process effectively eliminates contaminants in water, although small microorganisms can escape.
Ultra Violet filter – UV filters create ultra violet radiation, even more extreme than sunlight, to kills germs like bacteria, algae, viruses, molds and oocysts, within the water. These filters are most effective only when water passing through the UV filtration is free of contamination. Sediments or contaminants present in water may cause shadows and hence stop the UV rays from hitting the germs.
As you can see, no 1 kind of filtration is enough to make water totally safe for drinking. The perfect combination would be RO and UV water purification process. And that is exactly what Kent water purifiers offer you. RO filtration stage ensures there are no impurities like sediments, heavy metals, salts or other contaminants. This water is then passed through the UV filter to kill any germs that might be present. And what you get is pure, clean and safe drinking water.
