Lists of respirators that are NIOSH-approved can be found on the NIOSH-Approved Particulate Filtering Facepiece Respirators webpage.

Disinfecting COVID 19 Test Kits personal protective equipment with pulsed xenon ultraviolet as a risk mitigation strategy for health care workers. The use of ethylene oxide, which is widespread in hospitals, is less safe than hydrogen peroxide vaporization and less environmentally friendly.

Subsequently, FFP respirators were subjected to a fit test to verify that they fit properly and that the filter material continued to be a good barrier against particles. The fit test results for an untreated FFP respirator showed an average value of 162. Therefore, a reprocessed FFP respirator must have a minimum average value of 100 to pass the fit test. Based on these, it was preliminarily concluded that “double sterilization using a short process with hydrogen peroxide gives an acceptable result” . We must remember that either PPE (-FFP respirators) or medical face masks manufactured according to technical standards, require that they be discarded after use, since they are heat sensitive and are not designed to undergo a process as severe as sterilization . This is why manufacturers like 3M initially advised against the sterilization process .
Similarly, Spanish Society of Preventive Medicine, Public Health and Hygiene includes among the recommended decontamination methods for FFP respirators the UVGI with double lamp 36 W and exposure time of 148 s. They indicate an effectiveness of bacterial disinfection with 7log reduction and harmlessness on respirators. Another way to improve the fit of certain face masks is to double-mask — wear a disposable mask underneath a reusable cloth mask. It’s important to note that the CDC advises against double-masking while wearing respirators, and you should not wear two disposable masks. They’re designed with three layers of nonwoven fabric, an adjustable nose bridge and ear loops. A big part of the reason cloth or even surgical masks can be less effective is due to the gaps between the mask and the face.
Parents and caregivers may have questions about NIOSH-approved respirators for children. Although respirators may be available in smaller sizes, they are typically designed to be used by adults in workplaces, and therefore have not been tested for broad use in children. They filter at least 95% of particles in the air when approved by NIOSH and when you have a proper fit. Lists of masks that meet these standards and more information on their availability can be found on the NIOSH Personal Protective Equipment Information (PPE-Info) webpage. These masks have markings printed on the product to indicate they are authentic. CDC’s mask recommendationsprovide information that people can use to improve how well their masks protect them.
Because of the three different panels, the masks cover the nose and wrap under the chin while still sitting a bit away from their mouths, giving them space to talk and lick their lips without touching the mask. If you’ve witnessed the sight of a kid licking or sucking in and chewing the inside of their mask, lessening its efficacy, you already know how important this extra space is. Getting the absolute best fit out of a kid-size KF94, however, COVID 19 Test Kits can still be a little bit tricky. Disposable face masks are more likely to have gone through the NIOSH approval process. NIOSH approval means that your mask has gone through rigorous testing and has met or exceeded standards for particle blockage, filtration and safety. Since the purpose of the face shield is to provide more coverage to the wearer’s face – especially their eyes – face shields are used commonly in conjunction with a face mask.
He teaches fourth grade in Brooklyn and has tried a lot of KN95’s over the last two years. They are by far his favorite masks for work, and he says that, in addition to making him feel safe in the classroom before vaccines were available, they fit more snugly than the other KN95’s he has tried, and they don’t move when he is talking. Traditionally worn in hospitals for procedures and in surgical suites, surgical masks are generally thin and loose fitting.
