The Omnipure K5505JJ is a 10-inch inline GAC (Granular Activated Carbon) whole house water filter cartridge with 1/4" FPT (Female Pipe Thread) connections. It is designed to reduce chlorine taste and odor, sediment, and other common contaminants from your incoming water supply. The K5505JJ is ideal for point-of-entry applications, ice makers, refrigerators, and RV water systems where a compact inline carbon filter is needed.

The Omnipure K5505JJ features a nominal 20-micron filtration rating, making it effective at reducing sediment and particulates while the GAC media tackles chlorine, taste, and odor issues. It has a filtration capacity of approximately 1,500 gallons or 6 months of use, whichever comes first. Actual life may vary based on your water quality and usage volume.

The Omnipure K5505JJ is manufactured in a facility that adheres to NSF/ANSI Standard 42 guidelines for materials and construction, ensuring the components are safe for potable water contact. The GAC media used reduces chlorine taste and odor consistent with NSF/ANSI 42 performance standards. Always verify specific certification listings on the current product packaging for your application.

The Omnipure K5505JJ installs easily thanks to its built-in 1/4" FPT threaded connections on both ends — no separate housing required. Simply shut off the water supply, connect the filter inline with the flow direction arrow pointing toward the outlet (typically toward your appliance or faucet), and use thread tape to ensure a leak-free seal. After installation, flush the filter with 2–3 gallons of water to remove carbon fines before regular use.

Omnipure recommends replacing the K5505JJ every 6 months or after 1,500 gallons of filtered water, whichever comes first. If you notice a change in taste, odor, or a reduction in water flow before that interval, replace the filter sooner. Regular replacement ensures optimal chlorine reduction performance and maintains clean, great-tasting water throughout your home or appliance.
