The Omnipure K2533-KK is a premium inline granular activated carbon (GAC) filter with KDF-55 media, designed for point-of-use applications such as refrigerators, ice makers, reverse osmosis systems, and drinking water dispensers. The KDF-55 media enhances chlorine reduction and inhibits the growth of bacteria and algae within the filter, while the coconut shell carbon reduces chlorine taste, odor, and other chemical contaminants, delivering cleaner, better-tasting water and ice.

The Omnipure K2533-KK has a nominal 5-micron rating, effectively reducing fine sediment along with chlorine taste and odor. It has a rated filtration capacity of approximately 1,500 gallons or a service life of 12 months, whichever comes first. For optimal performance and water quality, we recommend replacing the K2533-KK annually even if the gallon capacity has not been reached.

The K2533-KK measures 2 inches in diameter by 10 inches in length and features 1/4-inch quick-connect (QC) push-in fittings on both ends, allowing for tool-free installation with standard 1/4-inch tubing. Its compact inline design makes it ideal for tight spaces behind refrigerators or under sinks, and the quick-connect fittings ensure a secure, leak-free connection without the need for additional adapters.

Yes, the Omnipure K2533-KK is manufactured in a facility that produces components tested and certified to NSF/ANSI Standard 42 for materials safety and aesthetic effects, including chlorine, taste, and odor reduction. The KDF-55 media used in this filter is also NSF-certified, ensuring the filter meets strict standards for drinking water contact materials and performance.

Installation is simple: shut off the water supply, cut your 1/4-inch water line, and push the tubing firmly into the quick-connect fittings on each end of the K2533-KK, paying attention to the directional flow arrow on the housing. Before use, flush the filter with approximately 2–3 gallons of water to remove carbon fines and activate the media. Replace the K2533-KK every 12 months or after 1,500 gallons to maintain peak filtration performance and water quality.
