N95 FACE MASK FOR SALE USED TO PREVENT CORONAVIRUS
An N95 respirator is a respiratory protective device that is made to achieve a very close facial fit and maximum filtration of airborne particles. This respirator blocks at least 95 percent of extremely small test particles making its capabilities exceed those of face mask for sale.
A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres, including particulate matter such as dust and airborne microorganisms, as well as hazardous fumes, vapors, and gases. There are two main categories: the air-purifying respirator in which respirable air is obtained by filtering a contaminated atmosphere, and the air-supplied respirator in which an alternate supply of breathable air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants. Face mask for sale filters at least 95% of airborne particles.
Air-purifying respirators range from relatively inexpensive single-use, disposable face masks sometimes referred to as a dust mask to more robust reusable models with replaceable cartridges often called a gas mask.
HOW TO WEAR THE N95 CORONAVIRUS FACE MASK
Always read and follow the directions when using an N95 respirator mask. It must cover both the nose and mouth to keep you from breathing in mold and dust and against other airborne diseases. If it does not have a snug fit, it will not work properly. The correct fit of the mask requires contact with smooth skin. It will not work properly for people with beards or facial hair. Even one-day beard growth has been shown to let air leak in. Always use both straps on the mask to hold it in place to keep air from leaking around it.
HOW TO MAKE SURE THE MASK IS PROPERLY FIT
Do a user seal check, including both positive and negative pressure checks, to verify that you have correctly put on the mask and adjusted it to fit properly.
Negative pressure check
Place both hands completely over the mask and inhale sharply. Be careful not to disturb the position of the mask. The mask should pull into your face. If air leaks around your face or eyes, adjust the nosepiece and straps and repeat the positive pressure check.
Positive pressure check
Put your hands over the mask and breathe out sharply. If your mask has an exhalation valve (like the one pictured above) be sure to cover the exhalation valve when you exhale. No air should leak out of the mask if it fits properly. If air leaks out, readjust the nosepiece and straps and repeat the negative pressure check.
WHEN TO THROW OUT THE N95 RESPIRATOR (MASK)
As the N95 mask gets clogged, it becomes more difficult to breathe. When this occurs, throw this out and use a new one. Discard the mask if it is wet or dirty on the inside, if it is deformed, or if the filter is torn. A deformed mask may not fit properly.
NB. An N95 mask cannot be cleaned or disinfected.
