Filters for Reverse Osmosis

Membranes

Membranes on any filtration system need to be changed out when product water may begin to taste different or bad, indicating solids and organics are passing through the Reverse osmosis membrane. To be sure it’s the membrane, change the prefilter and postfilter first and check the TDS reading.

The life of the Reverse osmosis membrane cartridge depends mostly on the pH and hardness of the supply water to the Reverse osmosis system. Replace the membrane every 10 to 36 months.

Pre & Post Filters

It is recommended that all filters be changed at least annually or more frequently based on usage and local water conditions. The quantity and quality of the water processed effects the life of the filters.

The stages of your Reverse osmosis system typically range from 2-5 plus. Changing out the filters frequently helps keep higher quality water and can prolong the life of the Reverse osmosis membrane.

"We love how clean our granite and dishes stay now! My shower looks so much better too! I noticed my skin and hair felt better almost immediately after installing our Oasis Water System. Thank you again for improving our life in San Antonio!"

"John Hancock was very informative and answered all our questions. Since installing an Eco Water System we have seen an immediate difference! All our soaps immediately seemed softer in the shower and all the dishes are way cleaner! No water spots in the house is the best though! We definitely recommend Oasis Water Solutions to everyone! John really knows his product."

"We have had our Eco Water System for over two years now and we absolutely love it!! I haven't had a single problem with the system and the water is just as clean as the day I bought It. I just returned from an Army Deployment and was so glad to have soft water to shower in again, it's a huge difference on my skin. My wife is very pleased with how clean it has kept all our bathrooms and kitchen as well. We are very happy we invested in this system."
