4 Factor Considering Before You Buy A Water Purifier

The water quality that you get supplied at home will suggest how many purification stages the water has to go through to get the clean water for drinking and cooking purposes. Purifying water using a multi filtration process where different sediments that are harmful for human consumption are passed through different membranes and give you clear water.

Different types of water purifiers have different needs as well as requirements. UV and RO water purifier units need electricity and can eliminate the inorganic compounds and also the smell that is present in the contaminated water. Though the sediment cartridge and activated carbon filters get rid of the sand and foul odour, these do not need electricity but are not so effective in usually the inorganic salts. 

Here in this article, you will learn about four important factors that you should be considering while buying a water purifier for your residential or commercial area. Following these points will help you to choose better and will make your search easier and faster.

Quality Of The Water

In most of the houses, the water that is supplied by the municipality area is hard and it means that your house water has a high level of TDS or total dissolved solids in the water. TDS also include inorganic salts such as magnesium, calcium, sodium, potassium,  chlorides, bicarbonates and also sulphates. The best purifiers will help get rid of this kind of inorganic compounds like a Reverse Osmosis system. The RO membrane pore size is usually 0.005 micron that makes it extremely impossible for the dissolved solids to pass through and contaminate drinking water. 


Different areas have different types of Contaminants. The contaminated water that has heavy metals such as arsenic, lead, copper, iron and magnesium can become extremely toxic if consumed in high amounts. Because of the increasing number of factories and the infrastructural growth in society, these metals are contaminating the water because it is found in abundance in today’s world.

Nitrate Contamination is a cause for great concern. This is not only the result of the agricultural practices but is found where the fishes usually generally live. In reverse osmosis, the suspended and dissolved impurities get reduced, therefore it is advised to get an RO system. One more kind of filter you can look at is an ultraviolet filter where the water gets disinfected. In cases of UV filters, the harmful microorganisms cannot multiply in number due to the UV lamp and its radiation. One can choose to look at the RO based UV purifiers.

Another method of purification is the combination of UV and RO filters that has an Ultra Filter that helps to remove the suspended bacteria and it is the best when the water supply is free from total dissolved solids. There is an RO water purifier system that has mineral cartridges for different areas with a high amount of total dissolved solids.

Pressure Of Water

The incoming water supply flow determines the type of filter that you should be choosing. A reverse osmosis system will work properly with the use of high water pressure. The water pressure is dependent on the type of elevation of the building and also other factors such as clogged filters and blocked pipes. The water purifiers usually need to have a pressure of 5-40 pounds per square inch.

You can also attach a booster pump along with the Reverse osmosis system if the supply of water in your house has less pressure. Otherwise, you can also go for the activated carbon purifiers if the supply of water has less amount of TDS.


Electricity plays a very important role when you choose water purifiers. Some purifiers do not work unless it is connected to plug points. These are useful for a home that has a bad power supply and shortage. The UV or ultraviolet filter does not work if there is no electricity. This uses electricity to produce ultraviolet radiation which helps remove bacteria. The reverse osmosis system generally does not work without electricity as this uses electric power which provides you with the right amount of water pressure that is required for the RO membrane.

The activated carbon purifiers do not need electricity to run which is the same as the Ultra Filter and sediment filters. While UV and RO systems remove total dissolved solids and bacteria that cause water-borne diseases, the non-electric purifiers can also get rid of some of the chemicals that are dissolved in water, along with sand and germs. It is advised to get purifiers that run using electric power.

Now that we have learned some of the information on the differences and conditions between non-electric and electric water purifiers, we hope that you can decide on getting the right purifier based on the requirements and needs that you have. Some manufacturers provide you with the best options for you to choose from and also provide you with the worry-free conditions of getting the desired purifier in the comfort of your own home.
