Henry's MicroFresh Filter uses activated charcoal to reduce lingering odours in your home.

But how does it work?

Activated charcoal is formed when pure carbon is exposed to oxygen, this causes the carbon to fracture resulting in an increased surface area boosting its already fantastic odour absorbing properties.

The high-efficiency, MicroFresh Filter includes an additional charcoal-activated layer that effectively reduces lingering odours leaving your home feeling clean and smelling fresh.
