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. 

Technical Note 1: The US Centers For Disease Control and Prevention (CDC) has an FAQ question about using respirators with an exhalation valve.

Technical Note 2: Respirators with KN designations such as KN95 are not NIOSH-approved. While the US FDA has issued an Emergency Use Authorization for unapproved respirators under certain conditions, the market for KN95's is fraught with substandard and counterfeit products and  should be considered only when approved alternatives are unavailable.

Technical Note 3: NIOSH has issued Recommended Guidance for Extended Use and Limited Reuse of N95 Filtering Facepiece Respirators in Healthcare Settings which health care institutions will find useful. The US FDA has issued Emergency Use Authorizations for the use of hydrogen peroxide vapor systems to sterilize and reuse personal respiratory protective devices.

Case dimensions: 26" x 18" x 11" (66.0 x 45.7 x 27.9 cm), 14 lb (6.35 kg).

    The masks are genuine N99 NIOSH approved. We are EFR's / Rescue Divers with a small underwater rescue company and having high quality respirators when we are topside are vital to our crew. Thank you Safety Emporium for such great product.

  3. Wonderful service and great product 5 Star Review

    We ordered these masks for a medical practice and they've been great. Slightly harder to breathe in than an N95, but that's to be expected, since this has a higher particulate filter count. Customer service was great, we explained that these masks were for medical use and they expedited the shipping. We're so thankful to have found a reliable company with fair pricing during the pandemic. Thanks Safety Emporium!
