What's the difference between a mask and a respirator?
The terms respirator and mask are sometimes used interchangeably.
Surgical N95 respirators and standard N95 respirators are similar in appearance and both can effectively filter airborne biological particles such as viruses and bacteria when properly selected and worn. Surgical masks are a barrier to fluids. The key difference between a standard N95 respirator and a surgical N95 respirator is fluid resistance.
