As the name suggests the spore filter is a filter that filters out 99 % of the incoming spores, including botrytis cynera. Botrytis cynera is the fungus that causes rot in the flower. Use the spore filter for incoming air that does not contain spores and therefore offers no resistance to your plants.
These filters should be positioned in front of the incoming air.
These filters are also highly suitable for filtering air for your cuttings.
