This is a single H13 True HEPA replacement filter sized 14 x 5.25 x 1.25 inches for the Membrane Solutions MS18 and MS19 air purifier towers. It is rated to capture 99.97% of airborne particles down to 0.3 microns, the standard HEPA claim. The maker suggests swapping it about every six months. It is a consumable, not an upgrade: it restores the filtration the purifier was built around rather than adding features. Buyers should confirm their tower model and filter slot dimensions before ordering, since a filter that does not seat properly will leak air around the edges.
