COMPATIBILITY & APPLICATIONS
Where the K2566 Works Best
The Omnipure K2566 installs inline on reverse osmosis systems, under-sink configurations, or any application where fluoride reduction is desired. The activated alumina media provides targeted adsorption of fluoride ions while maintaining flow. Compatible with 1/4" NPT threaded connections. Note that NPT sizing measures larger than the fractional name suggests—1/4" NPT measures approximately 0.540" in actual diameter, not 0.25". This filter is ideal for users concerned about fluoride levels in municipal water supplies or well water applications.
💧 Pro Tip: When measuring NPT fittings, always verify the actual thread diameter with calipers or the reference chart—1/4" NPT does not measure 0.25" on a ruler. It measures approximately 0.540" in diameter, which prevents common sizing mistakes during installation.
