Masks vs Respirators

Earlier than we dive into the meat of this Guide, it is important to know that Surgical Masks and Respirators are two totally different types of protection. Respirators are usually more costly than surgical masks as they’re typically more hardy and do provide more protection. However, is the additional protection really essential throughout this current crisis?

Surgical Masks

As its name suggest, surgical masks were originally meant to be used during a surgery. The use was to ensure that the room could possibly be stored sterile, and that germs from a doctor or nurse’s mouth or nose wouldn’t contaminate the patient. Over the previous couple of years, it has seen commonplace use especially in places like China.

These masks are often also called three-ply masks on account of their attribute of having 3 layers of protection within the mask itself. The layers are often a constant type of material depending on the manufacturer, though widespread ones include wool felt, fiberglass paper, or polypropylene. The multi-layered construction of the mask acts to filter out particles more effectively, much like how utilizing multiple sieves in succession is more effective than just using one sieve.

Via a one-time use, the layers will start changing into soiled or clogged as they block out particles from each outside in and inside out. As there aren’t any approach to safely clean out these layers at residence, it is highly beneficial that these masks be disposed at the finish of its use.

These respirators come in several grades usually starting from N95 to N100. The numbers signify the share of particles that these respirators are presupposed to filter. For instance, N95 respirators are presupposed to filter out at the very least 95% of contaminants while N100 respirators are imagined to filter out no less than 99.ninety seven% of contaminants when they’re used properly.

These respirators have two key components that makes it totally different from a surgical mask:

The first is the shell, which has three key layers, typically more. The outer layer is a protective material which acts as a barrier between you and the environment. Within the center, the pre-filtration layer is thick and stiff to allow it to keep up a hard form, which is something that the surgical masks do not have. The final layer focuses on filtration and in ensuring that the air getting in from the atmosphere is filtered. Some types of masks have an added particular particulate air filters to help you breathe easier.

One other key component is its nostril clip, straps and foam. Not like a surgical mask, a respirator wants to make sure that all air going out and in goes by means of its filters. As such, these elements are there to create an airtight seal between you and your environment. If you’re utilizing a respirator, it is thus imperative that you just put it on properly.
