As its name suggests, the spore filter is a filter that captures 99% of incoming spores, including botrytis cinerea. Botrytis cinerea is a mould that causes flowers to rot. Use a spore filter in order to ensure that incoming air is spore free and therefore harmless to plants.
Filters should be positioned at the point incoming air enters the space. These filters are also ideal for filtering air for cuttings.
