Culligan H-53 Aqua-Cleer

The Culligan H-53 Reverse Osmosis System is a discontinued 3-stage RO water filter system that uses uses a sediment pre-filter to reduce sediment larger than 5 microns before the membrane filters out impurities larger than .001 microns. The carbon block post filter treats for taste and odor. You can find and order all your filters at once in our replacement kits below.


Due to a discontinued membrane, we recommend switching to the PureValue 5EZ50-RK RO Retrofit Kit for continued use. This retrofit kit allows for continued use your existing tank and faucet, and for an upgraded membrane to be used for updates in filtration technology. Please check your system as a different retrofit kit may be required.
