Seven Factors To Consider When Choosing The Best Reverse Osmosis System

When you shop online you should always look for the best reverse osmosis system.

There are hundreds of reverse osmosis systems on the market and thousands to come.

They all claim to be the best on the market but we know otherwise.

Choosing the best reverse osmosis system is important for several reasons.

For one, a reverse osmosis system can be costly. The system can cost as little as a few dollars to as much as a couple hundred dollars. This cost does not even include the cost for replacement filters and membranes for the system.

Then there is also the cost of installation and maintenance.

Last but not least, efficiency. How effective is the reverse osmosis system at removing contaminants and at what percentage.

While there is no clear cut way of identifying the best reverse osmosis system on the market, there are several factors that you should take into consideration when looking for the best reverse osmosis system on the market.

Key Factors To Consider When Looking For The Best Reverse Osmosis System

Quality Of The Membrane

Thin Film Composite and Cellulose Triacetate are the two (2) main types of membranes used in reverse osmosis systems.

The Cellulose Triacetate is stronger when it comes to facing chlorine and its by-products that would normally affect the membrane. This type of membrane is best for persons with chlorine or bad taste and odor problems.

On the other hand, you will find that the Thin Film composite membrane is better at removing more contaminants than the CTA. In order for you to choose the best reverse osmosis system, you should complete a water test.


The reverse osmosis water filter system that you choose should have a pre-filter to protect the membrane from clogging or fouling.

Pre- filters in reverse osmosis water filters are very effective in removing sediments and chlorine from the water before the water passes through the membrane.

Chlorine has a negative effect on the membrane and sediments will damage the pores of the membrane resulting in an ineffective membrane.

So choosing a reverse osmosis filter without a pre filter is not a good idea. What you should do is choose a reverse osmosis system with two or three pre-filters.

Quality Of Pre-Filters And Reverse Osmosis Membrane

Not only should you have a pre-filter but also the quality of the pre- filter should be good.

The membrane's quality should also be outstanding because the membrane is the main filtration medium used to purify water.

A good membrane will last at least 2 to 3 years and a good pre-filter will last 3 to 4 months.

Post Filters

Most reverse osmosis systems have one post filter. The best reverse osmosis systems have 2 post filters.

The extra post filter allows for complete filtration of the water even after the water has passed through 2 pre filters and a reverse osmosis membrane system.

Overall Price

Overall price is basically how much you would pay for the system, maintenance and replacement cartridges.

When shopping, the cheapest R.O. System can be the most expensive filter system in the long run. So you should include all costs in the overall price.

Gallons Per Day

How many gallons will it take to make one (1) gallon of pure filtered water. Some R.O. Systems take anywhere from 3 to 10 gallons to produce one (1) gallon.

3 to 5 gallons is ideal. Anything over that number you have to be prepared to pay the extra water bill.

Besides from how much water is used to produce one gallon of filtered water, you will also need to know how many gallons of filtered water will the reverse osmosis system produce.

The gallons will vary from 25 to 100 gallons a day.

We find that units that produce 50 gallons a day is satisfactory. Anything below that may be too slow for a large family and anything above 50 gallons, the quality may not be as good as the filter that produce 50 gallons a day.

Reverse Osmosis Storage Tank

You need a large enough reverse osmosis tank that will keep you supplied with water so you don't have to wait for water.

Reverse osmosis water filter systems take a long time to produce the high quality water that they produce so a large storage tank would be a plus being that you can accommodate the space for one.
