This is the set for the Watts Kwik Change RO system, 11", 50 gallons per day.
Included in the set:
The 5 micron Sediment cartridge - Watts Part #WQCSC11
Carbon Block filter - Watts part #WQCCC11
GAC post filter - Watts Part #WQCGAC11
Membrane is not included in this set, you change membrane every 3 years, you can add the membrane to this set by selecting yes in the membrane option.
These are the original factory replacements and are of excellent quality. Should be replaced every six to twelve months, depending on water usage. Installation is quite simple and quick.
The membrane is sold separately and is available in our store. A great value.
If you purchased your system from Costco or Sam's Club, these are not the filters for your system, you want to purchase the RO-Pure filters on our site.
