MATRIKX-CTO2-HD20 KX Technologies MatrikX Whole House Filter Replacement Cartridge

Quick Overview

Fits any standard housing that uses 20-inch x 4 1/2-inch replacement filter cartridges

Availability: In stockShips Today, Oct 04th



The MATRIKX + CTO2-HD20 water filters are the most widely used carbon block devices in the world and provide previously unattainable performance at the lowest price point. The dirt-holding capacity and the absence of carbon fines makes the KX-MATRIKX-CTO2-HD20 the filter of choice. A superior carbon block combines both high performance and integrity with an exceptional cost-to-performance value. As a result the KX-MATRIKX-CTO2-HD20 virtually renders GAC filters obsolete by comparison.
  • Drop-in cartridge provides quick and easy filter change
  • Optimized to perform as both a sediment and activated carbon filter
  • Radial flow (outside-to-inside) filtration provides increased dirt-holding capacity
  • Competitively Priced vs. GAC filters
  • Made in the U.S.A.
  • Genuine OEM Product

Great for your health! Review by Stephanie
To see the impurities on the filter makes me satisfied knowing they are not going into our bodies. Great investment in your health. (Posted on 2/8/13)
Great Review by Jim H
I bought this from Discount Filter Store rather than my local "water store" and saved over $35 for the same exact filter. (Posted on 7/21/14)
Great Service Review by JAH
They matched a lower price that I found online, elsewhere.
The filter was shipped promptly.
Courteous, professional customer service. (Posted on 7/2/15)
