Is the N95 mask washable? Washability of the N95 mask primarily depends on the design. There are some masks that cannot be washed as it may damage the filter. The outer layers of some masks can be washed but only after removing the middle filter layer.
Clean the respirator face piece (excluding the cartridges and filters) with either a pre-packaged respirator cleaning wipe or by immersing in warm cleaning solution, water temperature not to exceed 120° F, and scrub with soft brush until clean.
Is a surgical mask an N95 respirator? No. Surgical masks are not designed for use as particulate respirators and do not provide as much respiratory protection as an N95 respirator. Surgical masks provide barrier protection against droplets including large respiratory particles.
A number of companies have made both N95 masks and KN95 masks available online. The aptly named N95 Mask Co. has both types of masks available for the public to purchase.
If properly stored, masks should still be safe to use, according to Balmes. "If the masks are stored in a dark, dry place, they should be OK to use. The filter material is inert," he said. "At this critical time, N95 masks should definitely be used past the expiration date."
Respirators must be equipped with HEPA filtered cartridges (color coded purple) or an N-100, P-100 or R-100 NIOSH rating. These cartridges are specific for filtering out asbestos fibers. Paper dust masks available at hardware stores do not filter out asbestos fibers and should not be used.
Respirator Selection Air-purifying vs.Atmosphere-supplying Respirators
- Particulate Respirators. Capture particles in the air, such as dusts, mists, and fumes.
- Combination Respirators. Are normally used in atmospheres that contain hazards of both particulates and gases.
- Gas & Vapor Respirators.
Here is a breakdown of what an N95 mask is: N: This is a Respirator Rating Letter Class. It stands for “Non-Oil” meaning that if no oil-based particulates are present, then you can use the mask in the work environment. Other masks ratings are R (resistant to oil for 8 hours) and P (oil proof).
The N95 respirator is the most common of the seven types of particulate filtering facepiece respirators. This product filters at least 95% of airborne particles but is not resistant to oil. This web page provides a table of NIOSH-approved N95 respirators, listed alphabetically by manufacturer.
Respirators protect from exposure to airborne particles. In healthcare, protects from exposure to biological aerosols including viruses and bacteria. Surgical masks are a barrier to splashes, droplets, and spit. Respirators are designed to seal tight to the face of the wearer.
The CDC reports that prolonged N95 mask use (including between patients) can be safe for up to 8 hours, and encourages each user to review each manufacturer's recommendations prior to following this strategy. Current guidelines encourage wearing a face shield over the N95 to decrease the chances of soiling the mask.
After 50 hours of research and testing, we're confident that the 3M 8516 N95 Particulate Respirator is the best disposable respirator mask and the 3M Rugged Comfort Quick Latch Half Facepiece Reusable Respirator 6501QL/49488 is the best reusable respirator when used with N95 or P100 filters.
The re-use of disposable masks is considered safe in settings where an SCWA employee is entering a customer's home. It is important to wash your hands after each use and store it properly between uses. Remember, these masks are designed to block particulates from entering the lungs over a full shift of work.

N95 masks do NOT protect you against chemical vapors, gases, carbon monoxide, gasoline, asbestos, lead or low oxygen environments. If you have a pre-existing medical condition, wearing a mask may make breathing more difficult because you must pull air through the mask as you inhale.
When should an N95 respirator be changed?
- Check before putting on each time and replace if facepiece or head straps show any signs of damage or deterioration.
- Replace if facepiece is visibly dirty, splashed on, or becomes difficult to breathe through.
- Replace in accordance with your agency's infection control protocols.
