Culligan Compatible Replacement Filters

How much do Culligan water filters cost? Culligan propriety water filters can be very expensive. We offer compatible high-quality filters, RO membranes, cartridges, and lamps that cost much less but provide that same clean, great-tasting drinking water you'd expect. By installing Culligan-compatible reverse osmosis filter replacements and taking care of routine system maintenance yourself, you can save quite a bit of money.


NOTE: Some filters require a system "conversion kit" be installed first (such as the Culligan Aqua-Clear). A retrofit kit allows you to keep using your current Culligan tank and faucet, but by installing a new manifold (component that holds the filters), you're able to use less expensive Culligan-compatible filters going forward. Our customer support team is happy to answer any questions you might have about this process. 877-377-9876 Mon-Friday, 8 am to 5 pm CT.
