3M Filter Type 1 SV-SPF1 Fine Particle Thin HEPA

3M filters have a higher collection capacity than other vacuum systems. Each filter is encased in durable plastic container which virtually eliminates spillage and makes them easy to remove and safe for disposal. Larger capacity requires replacing less often. When the filter is full, the whole cartridge is simply removed and discarded. Type 1 fine particle filter: a thinner, more concentracted weave (HEPA media) for trapping extremely fine particles. Typical applications - laser printer using toners in the range of .3 to .5 microns and highly-sensitive equipment.
