Please check with your local pharmacy for availability of free N95 masks provided by the Oklahoma State Department of Health.

An N95 mask is a filtering facepiece respirator (FFR). The Federal Code of Regulations defines a FFR to be a negative pressure particulate respirator with a filter as an integral part of the facepiece or with the entire facepiece composed of the filtering medium. An N95 means the mask has been rated to filter at least 95 percent of airborne particles it encounters. The masks have also been manufactured to form a seal on the wearers face. They can be referenced as a disposable respirator, dust mask, N95, KN95, FFR, etc.

The difference between an N95 and a KN95 mask is where the mask is certified. Much like other industries, respirators/masks have different approval sources and names.
