The Omnipure K2333-KK is a granular activated carbon (GAC) inline filter manufactured by Omnipure Filter Company. It is specifically designed for polishing and taste/odor reduction in applications such as refrigerators, ice makers, reverse osmosis systems, and drinking water lines. The K2333-KK uses high-quality coconut shell carbon to reduce chlorine taste, odors, and other aesthetic impurities, providing cleaner, better-tasting water and ice.

The Omnipure K2333-KK features a nominal micron rating suited for polishing applications and has a rated capacity of approximately 1,500 gallons. For best performance, it is recommended to replace the K2333-KK every 6 to 12 months, depending on your water usage and incoming water quality. Replacing it on schedule ensures consistent flow and optimal chlorine and odor reduction.

The Omnipure K2333-KK comes equipped with 1/4" quick-connect (QC) push-in fittings on both ends, making it easy to install in standard 1/4" water lines without the need for additional adapters. It has a recommended flow rate of 0.5 GPM (gallons per minute) and operates within a pressure range of 10–125 psi and temperature range of 40–100°F, making it ideal for cold water post-filtration applications.

Omnipure manufactures the K2333-KK in a facility that follows NSF/ANSI Standard 42 guidelines for materials and structural integrity for chlorine taste and odor reduction. Omnipure is a well-established U.S.-based manufacturer known for producing filters that meet strict quality standards for drinking water polishing applications.

The K2333-KK is most commonly installed as a post-filter or polishing filter on the output side of a reverse osmosis system, on the water line leading to a refrigerator or ice maker, or as an inline filter under the sink. Its compact size and 1/4" QC fittings make it easy to install in tight spaces. After installation, flush 2–3 gallons of water through the filter to remove carbon fines before regular use.
