Water Purifier : How To Select Best One For You

No matter how to wash your drinking tap water looks, there is not any certainty that it is pure and germfree. It could have microscopic germs that lead to diseases, modern age contaminants like lead and arsenic along with some rather high level of TDS (Total Dissolved Salts).

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

You also may think that boiling your water before you drink it is fine enough. However, this is nowhere near the reality. Boiling merely provides protection against microbial contamination caused by bacteria, virus, etc. it generally does not take away unsafe chemicals/new age contaminants like lead, pesticides and also physical impurities like mud, dust, rust, and etc..

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

Lots of families are turning to water purifiers to be certain that their drinking tap water is safe and healthy. But, with industry flooded with an array of brand names how do you know exactly what a water purifier to pick?

Just a little bit of analysis is that you want before you purchase your water purifier. The first and foremost thing you want to find out is what your own water condition is real. Once you know this you know what kind of water purifier you will need to purchase. Here’s what you will need to find out in regards to the various technologies available in the market.

Reverse Osmosis

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

RO (Reverse Osmosis) works by applying high stress over the water depending on the amount of salt material; it is subsequently forced through a 0.0001 micron, semi-permeable membrane. RO will allow cross filtration of water, wherever the contaminants are all caught in the system. The impure water moves one way and the wash water moves the following way. 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% of those TDS and all impurities present in the drinking water. These impurities could include bacteria, virus, protozoa, and cysts, coliform, physical and chemical contaminants etc..


UV water purifiers are ideal in locations where you eliminate tender drinking water like which from rivers or lakes along with where in fact the TDS degree is under 500mg.

In purifiers that use UV purification, a lamp is utilized to make UV beams to which the water is exposed. The UV rays penetrate into the microorganism and alter its DNA, the moment this is done subsequently it is essentially killed and can not lead to an infection and even replicate! This system destroys about 99.99 percent of most organisms which cause diseases!

These purifiers tend not to alter the chemical composition of the drinking water or change its particular taste. Since it generally does not change the chemical composition of plain water it cannot be utilized in areas at which you receive hard H20.

Carbon Adsorption

When water is handed across the carbon floor the contaminants have been attracted to the surface. The carbon is processed to produce it extremely porous, this provides a massive surface area for adsorption or chemical reactions. These carbon filters usually utilize high carbon or blocks of powdered carbon. It is actually a widely used engineering and is quite effective in getting rid of pesticides, herbicides, chlorine, adware and different chemicals. The quality of these filters is ranked with the size of particles that it can take out. A filter that measures 0.5 microns is significantly more effective compared to the one that steps 10 microns.

Ultra filtration (UF)

This procedure of purification eliminates dissolved solids among the sizes of 0.005-0.1 microns. Many times it is employed as a pre- treatment step ahead of Reverse Osmosis (RO). Even the extremely filtration system works like a molecular sieve also it divides molecules based on the size. The water enters through an extremely fine filter which retains most macromolecules that are over a certain size like colloids, microorganisms etc.. Smaller sized molecules like solvents go through the entire filter. They function best in places where the TDS level is beneath five hundred mg/liter.


This system of purification is ideal if you live in a region in which you obtain hard H20. To transform hard water to soft water, then the more drinking water is passed over an ion exchange resin. Drinking water flows across the surface and also dissolves the sodium. The calcium, magnesium and other cations precipitate onto your surface. Ion-exchange can decrease hardness in the drinking water. It may also become rid of contaminants like iron, lead, copper, barium, radium, and nitrates. This tech is usually integrated into water purifiers together with different techniques.
