The CarboAir Pre-Filter protects your CarboAir Carbon Filter from dust, dirt and airborne particles. Preventing your carbon filter from becoming blocked with particles and prolonging its life.
Our premium Pre-filter socks need to changed when they look dirty. They are ultra-efficient at removing dust particles and being thicker but less dense than some pre-filters mean less restriction of air flow compared to our competitors.
The life of the pre-filter depends on your environment, they can last months or weeks depending on the volume of particles they are removing from the air.
