4 factors to consider before buying a water purifier

Factors to consider when buying a water purifier
RO purification

The market is flooded with different types of water purifiers. Water purifiers range from simple water filters to advanced purifiers using membrane technology for filtration followed by disinfection with UV lamp filters.

The question arises as to which water purifier is correct for your home? Here are 4 important factors that you must consider before purchasing a water purifier:

Water Quality

If the water supplied to your home is high in TDS, hardness and salinity then RO is the best choice for your home. RO has a semi-permeable membrane which has pore size of .ooo5 microns. Such tiny pores can remove the tiniest of dissolved salt, metals and impurities.

For areas where water supplied to home is soft and has TDS under permissible limit, carbon activated filters can work well.

Contamination

Bacteria, nitrate, dissolved pesticides and lead are the most likely health-effecting contaminants present in water. The amount of contaminants present in water can be tested in any laboratory. If water supplied to your home is high in microbes and contaminants then a UV based RO filtration can be an intelligent choice.  The UV effect irradiate the water and penetrate the cells of bacteria and viruses, destroying their ability to reproduce. These organisms fail to multiply and eventually die. The RO membrane removes these dead germs and contaminants from water and make it fit for consumption.

Water pressure

Both UV and RO filters need water supply at a good pressure. If the incoming water flow does not have sufficient pressure, the RO filter will not work optimally. So if the pressure of water supplied to your home is insufficient (but the condition is that water is soft and less in impurities) it is best to go for the activated carbon purifiers. But if the water is high in TDS and contamination, then go for RO purifier. You can attach a pump to the RO filtration unit to boost the pressure.

Electricity

Although RO and UV filtration are advance water purification technologies, a big problem is that they need electricity to operate. This means that they cannot be useful if power-supply to your home is inconsistent. So if you live in area where electricity supply is erratic then go for activated carbon purifiers.
