However, are masks and respirators actually equal? Why are some masks more expensive than others? What do you have to search for in a mask? What can you do if a mask isn’t available? Let’s find out.
Masks vs Respirators
Before we dive into the meat of this Guide, you will need to know that Surgical Masks and Respirators are completely different types of protection. Respirators are usually more expensive than surgical masks as they are typically more hardy and do offer more protection. Nonetheless, is the additional protection really vital throughout this present crisis?
Surgical Masks
As its name suggest, surgical masks had been originally meant to be used during a surgery. The use was to ensure that the room might be kept sterile, and that germs from a doctor or nurse’s mouth or nostril wouldn’t contaminate the patient. Over the last few years, it has seen commonplace use especially in places like China.
These masks are sometimes also called 3-ply masks due to their attribute of having 3 layers of protection within the masks itself. The layers are often a constant type of fabric depending on the manufacturer, although widespread ones embody wool felt, fiberglass paper, or polypropylene. The multi-layered structure of the mask acts to filter out particles more effectively, similar to how utilizing multiple sieves in succession is more efficient 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 are not any way to safely clean out these layers at house, it is highly really helpful that these masks be disposed on the end of its use.
One thing to remember is that unlike respirators, masks aren’t airtight and usually are not meant to be. Their important function is to stop direct splashes of particles in or out out of your mouth and nose. This is completely different from respirators, whose position is to filter the air you breathe.
Surgical Respirators
As briefly mentioned, the first role of a surgical respirator is to filter the air you breathe and is meant to be airtight when used. In this Guide, we are going to give attention to the more widespread single-use respirators instead of heavy-duty reusable ones.
These respirators come in several grades usually ranging from N95 to N100. The numbers symbolize the proportion of particles that these respirators are supposed to filter. For example, N95 respirators are purported to filter out not less than 95% of contaminants while N100 respirators are imagined to filter out a minimum of 99.97% of contaminants when they’re used properly.
These respirators have two key components that makes it completely different from a surgical mask:
The first is the shell, which has three key layers, sometimes more. The outer layer is a protective fabric which acts as a barrier between you and the environment. In the middle, the pre-filtration layer is thick and stiff to permit it to maintain a hard kind, which is something that the surgical masks do not have. The ultimate layer focuses on filtration and in making certain that the air entering into from the atmosphere is filtered. Some types of masks have an added special particulate air filters to help you breathe easier.
Another key element is its nose clip, straps and foam. Unlike a surgical masks, a respirator needs to make sure that all air going out and in goes via 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 crucial that you put it on properly. One option to inform in case you have placed on the respirator properly is that it should develop into slightly more difficult to breathe as airflow velocity is reduced.
