Full product details
Read the full description
A coconut shell carbon block for 20" Jumbo housings, about 4.5" wide. It's the biggest in the MATRIKX CTO range, for larger homes that want chlorine, taste and odour reduction through the whole house. It's also rated for PFAS and chloramine.
Which one? The 5 micron CTO (20BCTO/GR) is the everyday choice. It's rated at over 193,000 litres of chlorine reduction at 26.6 L/min. The 1 micron CTO Plus (20BCTO-PLUS) filters finer. Change it every 6–12 months, or sooner if the taste comes back.
