How to Choose the Best RO Water Purifier for Health and Life Benefits?

Ever tried to pick out a reverse osmosis (RO) water filter out of so many varieties and brands?

Yes, it’s not that easy nowadays! When buying the best RO water purifier that can supply the cleanest drinking water for the family, you should consider the following factors:

- You should have an elementary knowledge on the principles of RO technology: what is reverse osmosis all about and which RO system types are available for home and commercial needs. After that, one may do some comparison-shopping asking questions concerning the excellence of materials used, the guarantee, the servicing.

- You need to check the brand of the membrane used in filter! It is of greatest significance, since, membrane is the key element, influencing the quality of reverse osmosis filtration. A membrane is probably to be of low-priced, poorer quality if the RO water system uses a basic non-brand membrane.

You can even know the quality and durability of a RO purifier, without really using the unit! Here are the methods of product evaluation:

- Know the total weight and strength of the system you want to purchase. It should weigh about 20-30 lbs and be built like a tank. Reverse osmosis systems of decent quality are usually thick and made of heavyweight polypropylene shell that is very long lasting and highly heat resistant.

- Dealer should provide a TDS meter, which indicates the Total Dissolved Solids in water. In addition, vendor can provide the user the ability to check the efficiency of water filter themselves. Dependable retailers will be sure of the purification ability of the RO systems they sell.

- RO water purifiers are usually Do-It-Yourself units. Thus, it will not be useless to check also the quality of instruction manual. Is it easy to read and contain pictures, illustrations so that it becomes easier to realize.

- All the parts of a water filter should be NSF certified: Aquasana, APEC, Crystal Quest are good examples. One should not buy RO system from sellers who do not want to disclose or do not know about the brands or makers of their filter parts. One should beware of those RO systems that claim to be built with NSF parts though having only few certified components.

- There are several pre-filters used in RO purifier besides the membrane. The quality of the water will be better if the system has more filters as they help in maintaining the life and durability of the RO membrane. It is highly recommended that one should not buy a system without at least four filter stages.

These are some of the basic and most useful tips to consider while purchasing a reverse osmosis water filter. Now, you may check some quality and popular RO water purifiers and alternative non-RO brands that we picked and reviewed.
