Characteristics Of Best Water Purifier

Regardless of how clean your drinking tap water appears, there is no certainty that it is pure and germ-free. It could contain microscopic pathogens that result in diseases, new age contaminants like lead and arsenic or some rather high degree of TDS (Total Dissolved Salts).

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

You also might think that boiling your water before you drink it is good enough. But this is nowhere near the truth. Boiling only provides protection against microbial contamination due to bacteria, virus, etc. it will not remove risky chemicals/new age contaminants like lead, pesticides and also physical impurities like sand, dust, rust, etc..

So what is it that you are able to do in order to be sure that the quality of drinking tap water your family gets is safe and pure?

Lots of families are turning to water purifiers to make certain that their drinking water is secure and healthy. However, with the market flooded with plenty of makes how exactly do you really know what water purifier to choose?

Just a little bit of research is all you need before you purchase your water filter. The first and most important thing you will need to learn is exactly what your own water condition is real. Once you know this you know the kind of water purifier that you want to purchase. Here’s what you have to learn more about the various technologies available in the market.

Reverse Osmosis

If you live in a region in which you buy hardware afterward RO water purifiers are ideal. If the TDS (Total Dissolved Salt) levels in your own water exceed the permissible limit then it poses a serious threat to your health. RO water purifiers reduce the TDS content in your own water to a permissible level and ought to be used only if the amount of Total Dissolved Salts in warm water is rather high.

RO (Reverse Osmosis) functions applying high strain to the drinking water depending on the amount of salt content; it is then driven via a 0.0001 micron, semi-permeable membrane. RO permits cross filtration of water, even wherever the contaminants are all captured in the fascia. The impure drinking water goes one of the ways and also the wash water moves another way. The cross filtration allows the impure drinking water to sweep the contaminants with it thus, preventing a build up.

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


UV water purifiers are ideal in places wherever you access tender drinking water like that from rivers or lakes as well as where the TDS amount is below 500-mg.

In purifiers that use UV purification, a lamp is used to make UV beams to which the drinking water is exposed. The UV rays penetrate into the microorganism and change its DNA, when this is done then it is essentially killed and can’t cause any infection or maybe replicate! This procedure destroys roughly 99.99% of most organisms that trigger diseases!

All these purifiers don’t change the chemical composition of the water or change its taste. Since it will not change the chemical composition of plain water it cannot be utilized in locations where you obtain hard water.

Carbon Adsorption

After drinking water is handed over the carbon surface the contaminants have been attracted to the surface. The carbon is refined to create it exceptionally porous, so this provides a large surface area for adsorption or chemical reactions. These carbon filters normally utilize high carbon or carbon blocks of powdered carbon dioxide. It is actually a commonly used technology and is quite effective in getting rid of pesticides, herbicides, chlorine, adware and different chemicals. The quality of these filters has been rated by the size of particles that it may eliminate. A filter which measures 0.5 micron is more effective than the one that steps 10 microns.

Extremely filtration (UF)

This procedure of purification removes dissolved solids among the sizes of 0.005-0.1 microns. A lot of times it is used as a pre-treatment step just before Reverse Osmosis (RO). Even the Ultrafiltration membrane works as a molecular sieve plus it separates molecules based on the size. The water passes through a very fine filter which retains most macromolecules that are over a certain size like colloids, microorganisms etc.. Smaller molecules like solvents pass throughout the filter. They perform great in locations where in fact the TDS amount is under five hundred mg/liter.


This method of purification is ideal if you live in an area where you obtain hard water. To transform hard water to warm water, the more water is passed over an ion exchange resin. Water flows across the surface and dissolves the sodium. The calcium, magnesium and other cations precipitate onto your surface. Ion-exchange can lower hardness in the water. It could also get rid of contaminants like iron, aluminum, lead, barium, radium, and nitrates. This tech is often integrated into water purifiers together with different techniques.
