Choose The Right Water Purifier For Your Home

Regardless of how clean your drinking tap water seems to be, there is not any certainty that it is pure and germ-free. It could contain microscopic pathogens that lead to diseases, new era contaminants like lead and arsenic along with a rather high amount of TDS (Total Dissolved Salts).

Around 8 leading cities in India, drinking water-borne diseases like cholera, jaundice and typhoid accounted for around 77% percent of all the diseases in India. The survey also threw light onto the fact that the TDS levels are far over the permissible amount in most regions in India, including cities like Mumbai, Delhi, Bangalore.

You may think that boiling your drinking water until you drink it is good enough. However, this is far from the facts. Boiling simply provides protection against microbial contamination due to bacteria, virus, plus it will not remove risky chemicals/new age contaminants like lead, pesticides and also physical impurities like mud, dust, rust, etc..)

Therefore what is it that you can do to be certain that the quality of drinking tap water that your family will get is pure and safe?

Lots of families are turning to water purifiers to ensure that their drinking water is safe and healthy. But, with industry bombarded with an array of brands how do you really know what water purifier to choose?

A little bit of research is all that you want until you get your water filter. The first and most important thing you want to understand is what your own water condition is real. Knowing this you know what kind of water purifier that you want to buy. Here is what you want to learn more about the various technologies available in the market.

Reverse Osmosis

If you live in an area in which you get hard water then RO water purifiers are ideal. If the TDS (Total Dissolved Salt) degrees in your water exceed the permissible limit afterward it poses a serious risk to your health. RO water purifiers reduce the TDS material in your own water to a permissible level and must be utilized only if the amount of Total Dissolved Salts in warm water is rather high.

RO (Reverse Osmosis) works by applying high stress onto the drinking water depending on the degree of salt material; it is then forced through a 0.0001 micron, semi-permeable membrane. RO makes it possible for cross filtration of water, even wherever the contaminants are captured in the tissue. The impure water goes one of the ways and the clean water travels another manner. The cross filtration permits the impure water to sweep away the contaminants with it thus, preventing a build up.

Typical RO purifiers remove more than 90 percent of those TDS and all impurities found in the drinking water. These impurities could include bacteria, virus, protozoa, and cysts, coliform, physical and chemical contaminants etc.


UV water purifiers are ideal for areas where you purchase tender water like which from rivers or lakes as well as at which in fact the TDS degree is below 500mg.

In purifiers that use UV purification, a lamp is used to create UV rays to which the water is subjected. Even the ultraviolet rays penetrate into the microorganism and change its DNA, the moment this is done subsequently it is essentially killed and can not result in any infection and maybe reproduce! This procedure destroys about 99.99% of most organisms that lead to diseases!

These purifiers don’t alter the chemical composition of their water or change its taste. Since it can’t alter the chemical composition of plain water it cannot be utilized in places at which you obtain hard H20.

Carbon Adsorption

After water is passed over the carbon surface area the contaminants are attracted to your outer lining. The carbon is refined to make it exceptionally porous, so this provides a huge surface area for adsorption or chemical reactions. These carbon filters usually use granular carbon or carbon cubes of powdered carbon dioxide. It is actually a commonly used technological innovation and is quite effective in getting rid of pesticides, herbicides, chlorine, adware and different chemicals. The quality of those filters has been rated by the size of particles that it can get rid of. A filter which actions 0.5 micron is more effective compared to the one who actions 10 microns.

Ultra filtration (UF)

This procedure of purification eliminates dissolved solids involving your sizes of 0.005-0.1 microns. A lot of times it is employed as a pretreatment measure previous to Reverse Osmosis (RO). The Ultra filtration system works being a molecular sieve plus it separates molecules based on the size. The water passes via an extremely fine filter which retains all macromolecules that are over a certain size like colloids, microorganisms etc.. More compact molecules like solvents go through the filter. They operate best in places where in fact the TDS amount is below 500 mg/liter.


This system of purification is ideal if you live in a region where you get hard water. To change hard water to soft water, then the drinking water is passed within an ion exchange resin. Water flows across the surface also dissolves the sodium. The calcium, magnesium and other cations precipitate onto the top layer. Ion-exchange can decrease hardness in the water. It can also acquire rid of contaminants like iron, lead, copper, barium, radium, and nitrates. This tech is usually integrated into water purifiers together with different techniques.
