Replacing Your L-Series Filter
- Shut off water supply and relieve system pressure by opening the faucet until water stops flowing.

- Insert the new L5633 cartridge and twist clockwise until it locks securely into place.
- Turn water supply back on slowly and flush the system for 3-5 minutes to clear carbon fines and activate the filter media.
- Check all connections for leaks and monitor flow rate to confirm proper installation.
System Fit & Application
The Omnipure L5633 is designed exclusively for Omnipure L-Series filter housings with twist-off connections. This 12-inch T33 carbon block is commonly used as a post-filter in reverse osmosis systems or as a standalone inline filter for refrigerators, ice makers, and point-of-use applications. The 2.5-inch diameter fits standard L-Series mounting brackets. Verify your existing housing accepts L-Series cartridges before ordering, as this proprietary twist-lock design is not compatible with standard 10-inch or other inline filter formats.
