RO Filter System: The Ultimate Maintenance Guide


Taking proper care of your reverse osmosis system will mean the difference between a long-lasting household aid and having to replace the filter more often than your wallet would like. The entire process is not complicated, but in order to maintain your filtering system and make it last for ten or fifteen years, you will need to follow a few guidelines. Let’s take a look at what kind of care will make your RO system last for a long time.

Filter replacement

Different types of filters should be replaced at different intervals and you can easily stay on track of your filter status by checking the manufacturer’s manual and replacing it accordingly. The reverse osmosis membrane is meant to eliminate all contaminants from the water and it only needs replacement after two or three years of use, although it will mostly depend on the amount of water consumption and water quality.

Generally speaking, you should replace your carbon filter every twelve months. It is designed to eliminate contaminants as well as chlorine that can affect the longevity of your reverse osmosis system. Additionally, it eliminates the unpleasant taste and odour usually present in water treated with additives.

A sediment filter also requires annual replacement and is designed to stop sediment, dirt and other debris from contaminating delicate membranes of your reverse osmosis system. Make sure to avoid damaging your RO system by changing the filter on time and per the manufacturer’s instructions.

A polishing filter in a four-stage reverse osmosis system serves as a final polishing stage where the water will go through one final cleaning process that will remove bad taste and odour, delivering water that is completely safe for consumption. If you don’t change the filter in time, you will cause damage to the system and also cause decreased water production. Therefore, pay attention to the water flow and if you notice that the flow is weaker than usual, it means that your filters are due for replacement.

Cleaning and maintenance

You should thoroughly clean your RO system when changing the filters. Top-of-the-line units, as the Clear Choice Water Filters reverse osmosis system, should be sanitized and recharged in order to ensure its peak performance in the years to come.

First of all, the main valve needs to be shut off and drained all of the water from the RO system. Next, you want the carbon and the sediment filters remove from their housing along with the RO membrane. The filters should remain out of the housing but you should screw the housing back in its place and then pour one cup of hydrogen-peroxide into the first stage housing. 

Then, all connections should be re-attached and turned on the valve allowing the systems to run for at least two cycles. You can then shut off the main valve again and have new filters installed, after which you should let the tank fill back up and then drain it one more time.

How to handle hard water

Note that the reverse osmosis system cannot handle water hardened by minerals such as calcium and magnesium, as they can clog and damage it, so you need to use a water softener if you have hard water in your home. The softener will address the problem by eliminating the hardening elements from the water prior to it reaching the RO system. In turn, the RO system will clean the water of any residual salt from the softening process, providing you with completely clean and healthy water.

The reverse osmosis system presents a premium solution for home and office water filtration, delivering healthy, fresh and delicious water. If you want your RO system to last for years on end, make sure to follow these guidelines that will guarantee that you and your loved ones are drink the best water possible.
