The Omnipure ELF-1M is an inline water filtration system featuring a 1-micron carbon block filter housed in a disposable polypropylene shell with 1/4" quick-connect fittings. It is designed to reduce chlorine taste and odor, sediment, rust particles, and fine particulates down to 1 micron. This compact inline filter is ideal for icemakers, refrigerators, RVs, coffee makers, and point-of-use drinking water applications where space is limited.

The Omnipure ELF-1M has a rated capacity of approximately 1,500 gallons or 12 months of service life, whichever comes first. It operates at a flow rate of 0.5 gallons per minute (GPM) with a maximum pressure rating of 125 psi and a temperature range of 40°F to 100°F. Actual lifespan may vary depending on incoming water quality and usage volume.

The Omnipure ELF-1M measures approximately 2" in diameter by 10" in length and comes equipped with integrated 1/4" quick-connect (John Guest style) push-in fittings on both ends, eliminating the need for additional adapters. The carbon block media provides 1-micron nominal filtration, making it effective at capturing fine sediment and chlorine while maintaining consistent flow throughout its service life.

Installation is straightforward thanks to the built-in 1/4" quick-connect fittings—simply push your existing 1/4" tubing into each end of the filter, ensuring proper flow direction as indicated by the arrow on the housing. When replacing, shut off the water supply, press the collet on each fitting to release the tubing, and insert the new ELF-1M in the same orientation. Flush 2–3 gallons through the filter before use to remove carbon fines and activate the media.

Yes, the Omnipure ELF-1M is universally compatible with any appliance or system using standard 1/4" water supply tubing, including most refrigerators, icemakers, under-sink drinking water systems, RVs, and espresso machines. Because it is an inline filter rather than a proprietary cartridge, it works independently of brand-specific filter housings, making it a versatile replacement or upgrade option for post-filtration or dedicated drinking water lines.
