Filters should only be used in dry applications, as water can damage the filter element. HafcoVac filters are also compatible with most Nortech vacuums, with whom we have no affiliation. All filters include a set of 3 retaining springs.
Standard Filters contain a 10 micron filter element. For increased filtration needs we recommend our HEPA filter which is 99.97% efficient @ .3µ. Click here for more information on HafcoVac HEPA Filtration.
