Respiratory Protection

Respirators are rated by the type of contaminants and how much they filter out. Each rating has a letter (N) and number (95). The numbers refer to the percentage of one-micrometer particles removed during trials.

R95 Masks are suitable for eight hours of exposure to oil-based contamination. Whereas a P95 mask can last up to forty hours due to its stronger oil resistance. Oil based contaminants are common in fields that spray with paint and pesticides. The safety material on your hazard will inform you as to whether you need a P95, R95, or N95 mask.

N95 Masks are effective against preventing the spread of covid-19, swine flu, avian flu, and common flu viruses. a 3M 8210 N95 Mask fit over the nose and mouth without the more taxing filtration of reusable respirator masks. Regardless, the edges are designed to fit snugly to prevent air leakage.

Reusable respirators surpass the filtration abilities of disposable masks, because cartridges can filter organic vapors such as tear gas. Reusable respirators can be stored for years when left unopened. Properly cared for masks can last years as well, but should be replaced immediately once a tight seal for no loner be kept. 

Filters and cartridges are used with reusable half and full face respirators. Reusable respirators provide a more secure fit for the user. 

Ensure that filters and cartridges are changed when needed. High risk environments should take caution and change filters frequently.
