The KX MATRIKX CTO2-HD20 features a 10-micron nominal rating, making it highly effective at reducing chlorine taste and odor, sediment, and fine particulates from your whole house water supply. Its extruded carbon block construction ensures consistent contaminant reduction throughout the entire service life of the filter, delivering cleaner, better-tasting water at every tap in your home.

The MATRIKX CTO2-HD20 measures 20 inches in length by 4.5 inches in diameter (Big Blue size), making it compatible with most standard 20" x 4.5" whole house filter housings. This heavy-duty (HD) cartridge is engineered for high-flow whole house applications and fits popular housings such as Pentek, Culligan HD-950A, and other Big Blue-style systems requiring a 20-inch cartridge.

The KX MATRIKX CTO2-HD20 has a service life of approximately 6 months or up to 100,000 gallons under typical municipal water conditions, whichever comes first. Actual filter life depends on incoming water quality, sediment load, and household usage. Homes with heavier sediment or high chlorine levels may need to replace the cartridge more frequently to maintain optimal flow rate and contaminant reduction.

Yes, the KX MATRIKX CTO2 series is tested and certified to NSF/ANSI Standard 42 for chlorine taste and odor reduction, and the materials meet NSF/ANSI Standard 61 for drinking water system components. The CTO2-HD20 is manufactured using KX Technologies' proprietary extruded carbon block process, ensuring no binders, adhesives, or lubricants that could leach into your water.

The MATRIKX CTO2-HD20 is specifically engineered to reduce free chlorine, chlorine taste and odor, sediment, rust, scale particles, and other fine particulates down to 10 microns. Thanks to its high-capacity extruded carbon block design, it delivers excellent chemical reduction performance at high flow rates, making it ideal as a primary whole house carbon filter for municipally treated water supplies.
