What you need to know before buying a water purifier

The way to the best water purifiers in the market is not outlined in a map, but there are reviews that can help you in your search.


Water being the most vital element of our life, its purity should be accorded the highest priority by each of us.  Water is our Life Line. Many diseases in the third world are either water-borne or due to contaminated water. Unlike the western countries where tap water is safe for drinking, the water that comes through taps in the developing world is unfit for drinking. Every household thus requires a water purification system.

With the market being flooded with water purifiers each promising the purest drinking water, it’s tough to select one. Unlike any other appliance the purchase of a water purifier requires much more deliberation because it involves the health and safety of you and your family. The most important factors to consider is the quality of water, filter type and purification method. Our guide will help you to select a purifier which is the best for you and your family so that you don’t compromise with the health of your loved ones.

Water is purified by any one or a combination of the following methods.

Pre-filtration:  Prior to main filtration, the water is made to go through a pre-filter. The design of pre-filters is such that it removes dust, silt and sediments from the water. A pre-filter is rated by the size of particles (expressed in microns)it can eliminate.

  • Improves the efficiency of the main filter(RO/UV)
  • Prevents damage to the main filter
  • Boosts the life of the main filter

Sediment filtration: It uses the principle of gravity for filtration. When water passes through the filter, suspended particles get trapped onto the surface of the filter.

  • Used for pre filtration In RO filters.
  • It requires regular filter replacement.

Activated Carbon filtration (AC): Carbon granules or blocks are charged with silver molecules.  When water passes through this filter, impurities are trapped in the pores of the filter.

  • The particle size that the filter can trap is specified in the filter description.
  • Used as pre-filters

How it works: water pressure forces water molecules through a semi permeable membrane having extremely tiny pores of a certain size(measured in microns).
