10 good N95, KN95 and surgical masks to buy right now


According to a spring 2021 report, if an infected and uninfected person wore cloth masks, it would take about 27 minutes for an infectious dose of COVID-19 to reach the uninfected person. If they both wear surgical masks, this time increases to about an hour. And if they both carry N95 unattended, it would take 25 hours to receive an infectious dose. This was before the Delta or Omicron variants, but should give you an idea of ​​their levels of effectiveness with each other.

How can I avoid fake masks?

There are several ways to detect counterfeit N95 masks, such as looking for marks on the mask or avoiding N95 masks marketed for children (as NIOSH does not approve any respirators for children). The CDC offers a much more comprehensive guide on how to prevent N95 counterfeits instead.

We don’t recommend buying any masks you see on Amazon, as Amazon allows third-party sellers on its platform not to examine products as well as those sold by Amazon.com. Walmart, Target, and other retailers may also sell third-party masks. The masks on this list are generally legitimate, as are many masks you’ll find on major retailers like CVS or American manufacturers.

At the beginning of the pandemic, the CDC authorized the emergency use of KN95, KF94 and other non-N95 masks in healthcare settings, but this order was revoked in June 2021. However, many KN95 masks or KF94 are still more than suitable for every day. they are used for low-risk people, and are much better than no mask. So when you buy a mask, consider what your needs are and how you plan to use the masks you buy.

Can I reuse disposable masks?

If you go to a gas station for two minutes on the way to work with a new N95, do you have to throw it away and use a new one when you get to work? Not exactly.

According to CDC guidelines, N95 masks will lose their effectiveness over the course of a few hours, but they will also be less effective the more often they are put on and taken off. Part of the reason for this is that the elastic bands wear out and result in a less tight fit. The CDC recommends that if you do not find data from the manufacturer of your mask on how many times you can put on and take off a mask, do not remove and replace a mask more than five times. However, this advice is given in the context of the hospital environment.
