Air cleansing and fan maintenance: Cross section of a carbon filter.
A crucial component of any decent ventilation system is an active carbon filter. Not only does it cleanse the air of any potential pollutants or odours from the grow room or grow tent, it also extends the lifetime of the extractor fan, as it stop dust and pollutants from collecting in the fan.
Attached using a fast clamp, directly in front of the extractor fan, the extracted air is drawn through the filter fleece and the active carbon particles in the carbon filter, which removes nearly all particles and odours.
In a normal environment with a normal level of air humidity, a carbon filter may be used for up to a year, after which (or once the fan performance is reduced), we recommend that the filter is replaced.
