N95 masks are rated to capture at least 95% of particles

N95 respirators are a good choice to healthcare workers because they provide excellent protection from airborne particles. They are rated at capturing at least 95% of particles of 0.3 millimeter size and are effective even in the presence other contaminants. N95 respirators are excellent for protecting against airborne particles if used with a good facial seal.

They are available at major retailers

Some major retailers are starting to distribute free N95 face masks. Walgreens is one such store. The company provided a list of participating stores, and stated that it has already sent the first wave of masks. As more stores sign up, the supply of N95 masks will expand, and Walgreens hopes to have them in all of its stores by mid-February. The company says customers may only receive three free masks per visit.

They can be re-used

Re-use of N95 masks is an excellent option for sanitary conditions. The mask is made of hydrophobic polypropylene. N95 masks can capture particles as small 0.3 microns using filtration media. However, the filtration capacity of N95 masks is influenced by several factors, including extended use, re-use, and processing.

An N95 mask is a disposable filtering facial respirator that has two straps. They protect against hazardous airborne particles, but they do not offer protection from gases or vapors. N95 masks can be purchased at hardware stores, industrial supplies stores, and online. There are also some state and federal agencies that distribute these masks.
