There are a number of ways to spot counterfeit N95 masks, such as by looking for markings on the mask itself or by avoiding N95 masks marketed to children (since the NIOSH doesn’t approve any type of respirators for kids). The CDC offers much more thorough guidance on how to avoid N95 counterfeits on its site. Titan Protect’s masks are another pricey option, but you do get a lot more per box than the ones listed above. The NIOSH-certified mask has an adjustable aluminum nosepiece , an upper and lower head strap for a secure seal, and a flat-fold design that’s meant to fit most faces.
Therefore, it would be necessary to develop methods or procedures that can eliminate this uncertainty. In this regard, Fisher and Shaffer established a method to evaluate decontamination of inner layers of FFP respirators using ultraviolet-C. Therefore, based on this study, a standard procedure could be established to evaluate the effectiveness of UVGI in the inner layers and confirm or rule out its possible use for the inactivation of the coronavirus in FFP respirators. Face masks are one tool utilized for preventing the spread of disease. They may also be called dental, isolation, laser, medical, procedure, or surgical masks.
When shopping for a mask, keep in mind what your needs are and how you plan to use the masks you buy. You can double-mask with a surgical mask and a cloth mask, but it’s important to keep in mind that for N95s, this might alter their effectiveness.

The most effective cloth masks are made from at least two layers of fabric with a thread count of 180 or more and can be adjusted for a close fit around the face. In an effort to preserve supply for essential workers, many organizations including John Hopkins were offering patterns for home-made cloth masks. Fitted with a disposable mask liner, these masks can provide excellent protection up to 99% Bacterial Filter Efficiency.
So public health experts discouraged non-health-care workers from buying them. But now, they are much more readily available to the general public. And many American companies have started making NIOSH-approved N95’s in soft foldable shapes that are much more comfortable than the stiff cup styles. This one from Protective Health Gear is made in Patterson, New Jersey. Local manufacturing reduces any potential supply chain disruptions and ensures that each mask meets undergoes the strictest quality checks. To understand the benefits of , we need to first talk about the different types of common face masks available on the market today.
