Frequently Asked Questions

What is the micron rating of the KX MATRIKX CTO2-20 whole house filter?

The KX Technologies MATRIKX CTO2-20 features a 10-micron nominal rating, engineered using KX's proprietary extruded carbon block technology. This micron rating is specifically designed to reduce chlorine taste and odor while allowing strong flow rates suitable for whole house applications, making it ideal for point-of-entry systems that require consistent filtration without sacrificing pressure.

What is the filtration life and capacity of the MATRIKX CTO2-20 cartridge?

The MATRIKX CTO2-20 (20-inch Big Blue format) has a rated capacity of approximately 60,000 gallons for chlorine taste and odor reduction, or roughly 6 to 12 months of service life depending on your household water usage and incoming water quality. For whole house applications with heavy chlorine or sediment load, we recommend replacing the cartridge every 6 months to maintain optimal flow rate and contaminant reduction.

Is the KX MATRIKX CTO2-20 NSF/ANSI certified?

Yes, the KX MATRIKX CTO2 series is tested and certified to NSF/ANSI Standard 42 for chlorine taste and odor reduction, as well as NSF/ANSI Standard 61 for material safety. The carbon block is manufactured from FDA-compliant, acid-washed coconut shell carbon, ensuring no extractable contaminants leach into your drinking water during the filtration process.

What are the exact dimensions and fitment specifications of the CTO2-20?

The MATRIKX CTO2-20 measures 20 inches in length with a 4.5-inch outer diameter, designed to fit standard 20" Big Blue whole house housings. It operates within a temperature range of 40°F to 100°F, handles pressures up to 125 psi, and delivers an industry-leading flow rate of up to 8 GPM, making it one of the highest-flow carbon blocks in its class for whole house chlorine reduction.

What contaminants does the MATRIKX CTO2-20 reduce from whole house water?

The MATRIKX CTO2-20 is specifically engineered to reduce free chlorine, bad taste, unpleasant odors, and sediment throughout your entire home's water supply. Unlike standard carbon filters, KX's proprietary extruded carbon block process eliminates channeling and bypass, ensuring consistent contact time for superior chlorine reduction. Note that this cartridge is not rated for lead, cyst, or VOC removal — for those applications, consider a higher-grade KX MATRIKX filter variant.
