NIOSH approved for up to 16 contaminants

Eliminate the need to stock contaminant-specific cartridges. Willson Unisorb cartridges simplify training, ordering, and inventory. These economical cartridges offer lower breathing resistance than many similar products and feature a low profile for better visibility and weight distribution. An audible “locking” bayonet connection confirms cartridge attachment, preventing cross-threading and under/over tightening concerns. And for maximum flexibility, both standard and HEPA cartridges can be used on any Willson ValuAir™ Plus, Premier™ 6800, 6100 half-mask, or 6400/6500 Series full-facepiece respirators. Used alone, the standard Unisorb cartridge offers protection against a variety of contaminants, including hydrogen fluoride. When paired with a Willson N95 or P95 prefilter and filter retainer (P95 filter sold separately), the Unisorb is approved for use in environments containing dusts, mists, paint spray and pesticides. The Unisorb cartridge with P100 filter does not require a prefilter and also offers NIOSH-approved protection against asbestos-containing dusts and mists.

1 Standard Unisorb cartridge requires a Willson N95 or P95 prefilter.
2 Unisorb cartridge with P100 filter only.
3 Dusts, mists, fumes have a TWA >0.05mg/m.
