Why Catechin Filtration?
Catechin is a naturally occurring polyphenol with well-documented antimicrobial properties. When applied to HVAC filter media, it helps reduce the growth of bacteria and mold on the filter surface, contributing to cleaner, fresher air circulation throughout the conditioned space. Regular replacement of the catechin filter is recommended to maintain peak filtration performance and system efficiency.
