How Many Times Can I Reuse My N95 Mask? – NBC Los Angeles



How many times can I reuse my N95 mask?

It depends, but you should be able to use N95s and KN95s a few times.

The U.S. Centers of Disease Control and Prevention says health care workers can wear an N95 mask up to five times. But experts say how often the average person can safely wear one will vary depending on how it’s used.

Using the same mask to run to the grocery store, for example, is very different than wearing it all day at work.

The amount of time a mask is worn is more important than how frequently it’s worn, says Richard Flagan, who studies masks and aerosols at the California Institute of Technology.

In general, he recommends limiting the use of an N95 mask to about two or three days.

With every breath you take in an N95, particles accumulate on the mask, Flagan says. That could make it more difficult to breathe if the mask has trapped a lot of particles.

“They are degrading the performance of the mask,” Flagan says.

The elastic band on the mask could also get worn out and not fit around your face as snugly. It might also get dirty or wet, especially if you’re using it while exercising.

If you notice any of these changes to your mask, it’s time to stop using it — even if you’ve only used it a few hours. And since N95 masks can’t be washed, they should be thrown away once you can no longer use them.

Where Can I Get an N95 Mask for Free?

The U.S. government’s Strategic National Stockpile has distributed N95 respirators to pharmacy distribution centers throughout the country.

According to the CDC, major pharmacy chains like CVS, Walgreens and Rite aid will be offering free N95 masks, as will many independent locations.

Walmart, Target, Kroger, Hy-Vee, Meijer and Kroger stores with pharmacies will also be doling out the masks throughout their retail locations.

When Will Free N95 Masks Be Available?

Participating pharmacies will vary by state and territory, so will timeline for availability. Some locations have already began distributing masks while others said they will be available beginning next week.

Walgreens said participating stores “will have signage indicating mask availability.” Walmart said free masks will become available late next week, at the earliest.

Some CVS locations began offering free N95 masks on Thursday and Rite Aid said the face coverings will be available this weekend, with all stores receiving them by early February.

Call your local pharmacy or retailer to check on the status of their N95 mask stock.

There are different masks on the market: N95’s which are approved by the U.S. Government; KF94, approved by South Korea; and KN95, approved by China. Here are five ways to spot fake U.S. Government approved masks.
