Why are RO purifiers better?
Are RO purifiers better than others?
What is the difference between RO and other purifiers?
Can the bacteria in water be neutralized?
Do heavy metal chemicals accumulate in our body?
While considering purity of drinking water we tend to consider whether the water we are drinking is free from bacteria and viruses. We are wary of water borne diseases like cholera, typhoid, dysentry, etc.
Though these diseases are dangerous and have immediate effect on our health, but at the same time we should not be ignorant of health hazzards from other more alarming impurities present in water – impurities that can cause long term health disorders.
The dissolved of salts of heavy metals and harmful chemicals present in water pose far greater dangers to our health than the micro-biological impurities. Salts of Heavy Metals like Arsenic, Chromium, Lead, Mercury, etc. can cause lifelong damage to our health and can cause early death as well.
Though the bacteria and viruses present in water can be neutralised by boiling or by uv radiation, but the harmful chemicals and heavy metals present in water cannot be eliminated by these process. More importantly we may not even know that we are being slowly poisoned with heavy metal contamination as there is no taste or smell difference in water due to the presence of these dissolved impurities.
Heavy Metal chemicals in drinking water ‘bio-accumulate’ in our body, which means that once heavy metal is absorbed, our body cannot get rid of it. So even though there are no immediate problems, the heavy metals present in water can lead to cancer, stunted growth, nerve damage, and early death. Children are affected most from heavy metal pollution.
The best way to remove such dissolved salts of heavy metals and harmful chemicals is by using an Reverse Osmosis (RO) Water Purifier which can eliminate micro-biological, dissolved salts of heavy metals and chemical impurities.
There are various types of water purifiers available in the market today..ranging from simple water filters to advanced purifiers.

What are the different types of purifiers?
What are the advanced types of purifiers today?
What to do if water has high TDS?
How can water pressure be boosted?
Can RO purifiers be used at erratic electric supplies?
To help you overcome the confusion we have come up with 4 important factors that you must consider before purchasing a water purifier:
1. 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, minerals, chemical and metal impurities.
Bacteria, nitrate, dissolved pesticides and lead are the leading contaminants present in water, these days. The thyoe of contaminants present in water can be tested from a lab. This can help you decide the type of purifier that would be right for you. better idea If water supplied to your home is high in chemical, mineral and metallic impurities then RO Water Purifier is the right one for you
Both UV and RO filters need water supply above a certain pressure. If the incoming water does not have sufficient pressure, an RO filter will not work properly. So if the pressure of water supplied to your home is not proper it is advisable to go for an activated carbon purifier. But if the water is high in TDS and contamination, then go for RO purifier. By incorporating a pump to the RO filtration unit the Water pressurer can be boosted.
RO and UV filtration are advance water purification technologies, they need electricity to operate. This means that they cannot be used in areas where the power suply is erratic. Power-supply to your home is inconsistent. So if you live in areas where electricity supply is erratic then one should go for activated

What is the difference between RO and UF purifier?
What are RO purifiers based on?
Which is more better, RO or UF purifier?
What is the comparison between RO and UF purifier?
Can UF purifier remove dissolved salts?
The Purification by RO and UF are based on membranes. But the difference between the two is in the size of the pores in of their membranes. In an RO membrane the filtering pores are so small that it can even filter out salt molecules from the water. In the UF membrane the pores are larger and so it cannot filter out salt molecules.
Though the UF membrane is capable to filter out viruses from water, it cannot filter out the salts and metals from the water.
The advantage of the UF water purifier is that it works without electricity whereas RO Purifier requires electricity and hence is expensive compared to UF purifier. Other than the extremely small particles of salts the UF filter can filter out all other physical imppurities and is sure to filter out any disease causing germs, including the smallest of viruses. The UF membrane is also so small that it can filter out all dust and other particles and make the water safe to drink.
The only problem with UF water purifier is that in case any harmful dissolved salts are present in the water the UF membrane cannot filter it out. Only an RO water purifier can filter out harmful dissolved salts from the water. That is why the RO water purifier is considered superior to an UF water purifier.

What is the difference between RO and UV purifier?
Which is more better, RO or UV purifier?
Which one kills the germs more clearly, RO or UV purifier?
What is the comparison between RO and UV purifier?
Can algae get deposited on the UV bulb?
In RO water purifier the RO membrane physically removes all germs and viruses in the water by filtering out the micro-organisms. Apart from Removing Germs and Viruses, it can also remove dissolved salts and metals present in water by filtering it as the filtering holes in the RO membrane is extremelyy small.
In a UV water purifier the germs and other living organisms are paralysed by the UV radiation. The UV purification process only paralyses the germs but does not remove the paralyzed germs from water.
For the UV purifier to work properly, the UV light has to travel through the water for killing the micro-organisms. So if the water is not clear the UV rays may get blocked thus hampering the purification process. Also for the proper functioning of the UV Purifier the UV bulb should be clean and there should not be dirt attached to it or algae deposited on it. In case the UV light is off for sometime, algae can get deposited on the surface of the UV bulb and thus affecting the functioning of the Purfier.
