This our replacement filter set for a standard ProSeries 4 Stage reverse osmosis system. This set is designed to fit standard RO systems.
If you have any questions about sizing or fit, contact our customer support, 1-888-309-2837, and we'll help you get the right filters for your system.
Most reverse osmosis filter sets should be changed once per year. Depending on your water quality, filters generally get dirty and should be replaced in order to keep your membrane working properly, and keep cleaning contaminants out of your drinking water.
A sanitizer kit is also available as an add-on. When you change your filters you should sanitize your systems before replacing them, to help keep the system clear of any harmful bacteria.
Included in the set is the 5 Micron Sediment, a 10 micron carbon block, and a 10" inline GAC cartridge. You should change your RO filters every 12 months to maintain the highest quality of water and extend the life of your system. The membrane is not included in the set as it needs to be changed every 3-4 years.
