RO purifiers have semi-permeable membranes that possess a pore size of .ooo5 microns. These tiny pores help in removing even the tiniest of dissolved metals, salt, and impurities present in the water.
  • Storage capacity-  You wouldn’t want your water purifier to be out of freshwater during times of emergency or when you come back home after a tiring day. You would want your purifier to stay full at all times. Hence, look for purifiers with a capacity of at least 8 litres.
  • Purification process & Technology: If your household water is filled with nitrate, bacteria, dissolved pesticides, and lead, a UV-based RO filtration system would be the most intelligent choice for you.

RO Water Purifier Buying Guide

We understand how overwhelming you feel when you go out shopping for the best RO water purifier. Well, we believe that the list we have provided above will help you choose the right product without much hassle. You can simply click on the mentioned links and see on your own what are the special features of each of those products and which one of those suits your preference. However, it never hurts to know a thing or two about the RO Water Purifiers. You can read our buying guide and ensure enhancing your knowledge arsenal. Here are the key factors you should know and keep in mind before going shopping for RO Water Purifiers.

1. Wide range of filters

Today, the market is full of different types of water purifiers. They can range from simple water filters to some of the most advanced purifiers (including the ones we have listed above), such as ones with inbuilt membrane technology for extensive filtration. Purifiers equipped with UV lamp filters for disinfection are also commonly available. But the real question is, which water purifier should be correct for you?

Storage Capacity

In times of emergency, you would want your purifier to work and keep purified water all the time. This is where the storage capacity of a water puifier comes into play.  A water purifier should have ample storage capacity, but that also depends on your daily requirements. If you have a small family or a large family, it is obvious that you go for a capacity that can suffice the overall requirements. Our recommendation would be, look for purifiers with a capacity of at least 8 litres or more. The more the capacity, the better!

2. Consider Water Quality

Before deciding on which water filter to buy, make sure that you take into consideration the type of water that is available at your home. Ask yourself whether your domestic drinking water is full of TDS? Is the water hard? Is the water rich in salinity? If the answers to your questions are yes, then go for an RO water purifier. The reason is that RO purifiers have semi-permeable membranes with such tiny pores that remove hidden dissolved metals and impurities. In other cases, if the water supplied to your home is soft and contains TDS, carbon activated filters should work fine.

3. Contamination

Have you ever worried about what would happen to the health of your loved ones, if the water that you consume consists of germs like bacteria and viruses, and all the other types of dissolved chemicals and pesticides? Well, we feel for you, and we also understand that such water content will not only make you and your family members sick but would also attack your immune system, which, according to us, isn’t desirable at all.

To remove any of such microorganisms and chemicals from the water, you first need to get your water checked and figure out whether it contains such health-affecting contaminants. You may simply take the water to any laboratory and get it tested. Just in case you find that your domestic water has a high microbe content, or it is full of contaminants, any UV based RO filtration should be your preference.

4. Consider Water pressure

You must understand that both UV and RO filters need moderate water supply at good pressure. In case the incoming water at your home doesn’t flow with sufficient pressure, unfortunately, the RO filter wouldn’t provide optimal performance. Therefore, before choosing your water purifier, make sure that you take into account the average water pressure at your home.

You wouldn’t want to end up investing in a wrong system that doesn’t produce the best result. Such a failed investment doesn’t take much time to become a liability. For houses with insufficient water pressure, the best choice of purifier would be the activated carbon purifiers. However, they only work if the water is soft and free of contaminants.

In case your water doesn’t qualify, RO purifier should be your ultimate choice. However, if you neither have sufficient water pressure nor the water is clear of contaminants, all you can do is attach an external pump to the RO filtration unit and eventually help in boosting the water pressure.

5. Electricity is a key factor

You would probably understand that RO and UV filtration are some of the most advanced water purification technologies. However, there lies a big problem in terms of their operational tendencies. They require electricity for flawless running, and places that lack proper electricity infrastructure might find these water filtration technologies to be obsolete.

Without a fluent power supply, you can’t get the best advantage of the RO and UV water purifiers. If you live in such a locality where electricity supply fluctuates a lot, consider opting for activated carbon purifiers.

Here is a shortlist of bullets that will help you in deciding better on which type of filtration technology should work great for you:

  • Soft water, low TDS level: Ultra Filtration water purifiers work well
  • Soft water, high level of contamination: UV or UF+UV water purifier
  • Hard water, higher levels of TDS: RO water purifiers are best suited
  • Hard water, high levels of biological contamination: RO+UV+UF or RO+UV water purifier.

Remember that UF filters function best when working in combination with any other water purification system. This is mainly because they don’t kill any microorganisms present in the contaminated water. UF filters are only suited for the removal of suspended solid residue from the water. Activated carbon-based water purifiers help in removing excessive chlorine from drinking water.


Now that we have reached the climax of this article, we believe that you have gained some important knowledge regarding RO water purifiers. Our list should help you in deciding the best product available in the market. Besides, our buying guide is intended to help you make smart decisions later on during your life when you will require buying another filter.

However, it’s quite natural for you to get confused because of loads of choices available on our list. In that regard, let us recommend three of our favorite water purifiers that we believe you will like as well:

  • KENT Grand: We recommend KENT Grand because of multiple factors. First, it has a trustworthy brand and a commendable market presence. Besides, their double purification technology, and RO+UV/UF system remove all the dissolved impurities that also include bacteria, harsh chemicals, viruses, and salt.
