DuPure Ultra Pur RO Compatible Replacement Filters

The DuPure Ultra Pur reverse osmosis drinking water system uses expensive proprietary filters that offer no real benefits over other RO systems and the filters can only be purchased directly from DuPure authorized distributors.

Alternative Option to DuPure Filters: To reduce costs, save water, and produce purified water faster, consider converting your DuPure system to the PuROTwist Retrofit Kit (PT4000T75-RK). These are the same filters from the same manufacturer used by DuPure, but without the proprietary thread pitch connection DuPure uses. Going forward, this conversion kit allows you to use readily available Omnipure filters with your existing DuPure faucet, tank, and tubing. Start saving on replacement filters today!

IMPORTANT: The PuROTwist filter kits below only work if you convert your DuPure system with the PuROTwist Retrofit Kit (PT4000T75-RK).
