This our replacement filter set for the Culligan AC50 reverse osmosis system. Within a year, most reverse osmosis filter sets should be changed. Depending on your water quality, your filters generally get dirty and should be replaced to keep your membrane working properly, because it helps keep cleaning contaminants out of your drinking water.
The membrane is not included in this set but we do carry Culligan membranes. You can find the one that you need and add it to your cart and do a complete filter and membrane replacement.
We offer a sanitizer kit as an add-on so you can keep your drinking water system clean. When you change your filters it's highly recommended that you sanitize your systems before replacing them, to help keep the system clear of any harmful bacteria.
Filter set includes:
(1) 5 Micron Sediment
(1) Carbon Block filter
(1) Inline GAC cartridge 6" (1/4" Female with 2-3/8" fittings and 2-1/4" Fittings)
All three should be replaced once a year. Membrane is not included in this set, you change membrane every 3 years
