Bielcor® 's B300 advanced particulate filtering N99 dust masks are NIOSH-approved (approval number 84A-3907) and are designed to protect the wearer against non-oil-based particles as small as 0.3 microns, while still allowing the user full, deep breaths of clean, fresh air. Each has a flexible, adjustable metal nose piece that can be bent or shaped to ideally fit the user's face. The exhalation valve reduces excessive dampness and warmth in the mask from exhaled breath, making long-term wear much more comfortable. The flexible head strap allows the user to don and remove the mask with ease. These are readily compatible with other Personal Protective Equipment (PPE) such as safety glasses, goggles, earmuffs, and hardhats and the straps are latex-free.

These masks are ideal for protection against small particulates such as saw dust, metal shavings, pollen, allergens, fiberglass, and more. They are ideal for activities such as woodworking or painting at home as well as by professional carpenters, contractors, or lawn care specialists. N99 filtering respirators are even more efficient than N95 respirators, filtering at least 99% of airborne particles. These are not resistant to oil. NIOSH has a convenient discussion of particulate filtering respirator classifications on their web site.

This item contains 20 individual boxes suitable for resale. Each box includes 12 masks that are sealed inside an inner bag. The expiration date on these is August 2023.
