This 1 micron PES (Polyester) cartridge filter is for dry or wet vacuuming. A cartridge filter must always be used to prevent motor damage and dust inhalation. After wet vacuuming, allow the cartridge filter to dry, or replace it with a dry cartridge filter. Dry vacuuming with a wet cartridge filter will ruin the filter.
