PUR Faucet Filter Compatibility Guide
The PUR PFM400H and Ultimate are not compatible with: pull-down or pull-out faucets (the filter housing blocks retraction); faucets with non-standard aerator threads (most Grohe, some TOTO, and some European-spec faucets). PUR includes adapters for standard US residential faucet aerators (internal and external thread, standard sizes). For faucets without removable aerators (some TOTO Soft Flow models, some Moen integrated aerator designs), contact PUR customer service (1-888-787-5463) before purchasing to confirm compatibility. PUR faucet filters work on bathroom faucets as well as kitchen faucets -- useful for households who want filtered water at a bathroom sink for medication preparation or children's dental hygiene.
