Frequently Asked Questions
Are N99 Masks Washable?
According to approved practices, the B300 N99 mask can be worn again if sterilized. However, these masks are designed to be affordable, disposable respirator masks, which you can afford to change regularly.
Is the N99 Dust Mask Better Than the N95?
An N95 mask is approved as a surgical level mask as cleared by NIOSH. The N95 removes 95% of airborne particles. The N99 Mask is tested to even higher standards and must remove 99% non-oil-based particles from the air you breathe. In comparison, the N99 mask offers even greater protection.
Comparing N95, KN95, and FFP2 Respirator Masks
The difference between the N95, KN95, and FFP2 respirator masks is the country regulating and approving testing and performance standards. N95 is the basic and recommended standard for protecting healthcare workers in the United States and protecting against viruses like COVID-19. The KN95 applies in China and the FFP2 is used in Europe. These are similar yet different in airflow, particle filtration, and testing requirements. The N99 is a step-up in protection. It is the equivalent of the FFP3 in Europe.
To protect you from counterfeit masks in the marketplace, you should buy your official, stamped, and Certified N99 masks directly from Bielcor.

My first order of these was great. My second order was not so great. I wear eyeglasses, and need to pinch that around the top of my nose, to keep my eyeglasses from fogging up from my warm breath. I noticed the price has gone way down. I would rather pay the higher price, and have the better product.

I’ve noticed that some of the masks in the same package are more comfortable than others. They all seem to be the same size, but some just don’t stretch as much. They are a very good value, and a necessity these days. They are not thick, but do the job. The straps around your ears are not tight, and are easy to put on and take off. The metal strip over the nose is a perfect size.
