The MILWAUKEE N95 Valved Respirators are designed to help users stay cool while providing them with a better fit. The respirator valve reduces the construction mask's internal temperature by 10°F keeping users cool while at work. The respirator masks feature two soft adjustable straps and a flexible nose bridge allowing users to achieve a better fit. The respirator masks are NIOSH N95 approved for non-harmful sanding， grinding， sawing and insulation particles.
