Why are some masks more expensive than others? What do you have to search for in a masks? What are you able to do if a masks isn’t available? Let’s discover out.
Masks vs Respirators
Earlier than we dive into the meat of this Guide, it is very important know that Surgical Masks and Respirators are two different types of protection. Respirators are typically more expensive than surgical masks as they’re usually more hardy and do provide more protection. However, is the additional protection really needed during this present disaster?
As its name suggest, surgical masks were originally meant to be used throughout a surgery. The use was to ensure that the room could possibly be saved sterile, and that germs from a physician or nurse’s mouth or nose wouldn’t contaminate the patient. Over the previous few years, it has seen commonplace use especially in places like China.
These masks are sometimes also called three-ply masks as a consequence of their characteristic of getting 3 layers of protection within the mask itself. The layers are often a constant type of material relying on the manufacturer, though widespread ones embody wool felt, fiberglass paper, or polypropylene. The multi-layered construction of the masks acts to filter out particles more effectively, just like how utilizing multiple sieves in succession is more efficient than just using one sieve.
Through a one-time use, the layers will begin changing into dirty or clogged as they block out particles from both outside in and inside out. As there aren’t any solution to safely clean out these layers at dwelling, it’s highly advisable that these masks be disposed at the end of its use.
One thing to recollect is that not like respirators, masks are usually not airtight and will not be meant to be. Their main position is to prevent direct splashes of particles in or out from your mouth and nose. This is completely different from respirators, whose role is to filter the air you breathe.
As briefly mentioned, the first position of a surgical respirator is to filter the air you breathe and is meant to be airtight when used. In this Guide, we’ll deal with the more frequent single-use respirators instead of heavy-duty reusable ones.
These respirators come in several grades usually starting from N95 to N100. The numbers signify the proportion of particles that these respirators are speculated to filter. For instance, N95 respirators are alleged to filter out not less than 95% of contaminants while N100 respirators are alleged to filter out at the least 99.97% of contaminants when they’re used properly.
These respirators have key components that makes it totally different from a surgical masks:
The primary is the shell, which has three key layers, typically more. The outer layer is a protective cloth which acts as a barrier between you and the environment. Within the middle, the pre-filtration layer is thick and stiff to allow it to maintain a hard type, which is something that the surgical masks don’t have. The final layer focuses on filtration and in ensuring that the air entering into from the atmosphere is filtered. Some types of mask have an added particular particulate air filters that will help you breathe easier.
Another key element is its nostril clip, straps and foam. In contrast to a surgical mask, a respirator needs to ensure that all air going out and in goes by means of its filters. As such, these components are there to create an hermetic seal between you and your environment. If you are using a respirator, it’s thus imperative that you put it on properly. One option to inform if you have placed on the respirator properly is that it should turn out to be slightly more tough to breathe as airflow velocity is reduced.
