Our Valved Respirators with Gaskets are designed to help you stay cool while providing you with a better fit. The dust masks feature a comfortable tight sealing gasket creating a secure seal on your face for all day comfort. The respirator valve reduces the construction mask's internal temperature by 10deg keeping you cool while at work. MILWAUKEE masks feature two soft adjustable straps and a flexible nose bridge allowing you to achieve a better fit. The respirator masks are ideal for non-harmful sanding, grinding, sawing and insulation particles.
