Cloth vs N95: Which coronavirus mask should you wear?
-
Mask wearing has been a hotly debated topic, but most scientists agree that face coverings do help reduce the spread of the coronavirus, though the degree to which they do so depends on the quality of the masks themselves.To get more news about famous nonmedical mask wholesale, you can visit tnkme.com official website.
Because about one in three people who have COVID-19 display no symptoms at all, widespread use of masks remains important. A study which reviewed the evidence on mask wearing found in favour of widespread mask use by infected people as a way to help reduce community transmission, concluding that the available evidence suggests that near-universal adoption of any face covering at all, in combination with complementary public health measures, could successfully reduce the community spread of COVID. Models suggest that public mask wearing is most effective at reducing the spread of the virus when compliance is high.
At the start of the pandemic, there was a worldwide shortage of personal protective equipment (PPE) and governments advised the general public not to buy N95 or FFP2 masks so that they would remain available for front-line staff. N95 respirators, named for their ability to filter 95 percent or more of tiny 0.3-micrometre (μm) particles, are the mainstay of protection against airborne bacteria and viruses. The European equivalent FFP2 mask, which filters about 94 percent of aerosol particles, is also very effective.
When this advice was being given out, there was little understanding or agreement that SARS-CoV-2, the virus that causes COVID-19, was airborne; much of the focus was on droplet spread. The advice for the public was that cloth masks were appropriate in helping reduce the spread of large droplets.
But now, with the knowledge that the virus is mainly transmitted through tiny aerosol particles that can linger in the air for hours, is it time for governments and health authorities to update their advice? The short answer is: “Yes.” If you are able to access N95 or FFP2 masks, you should wear one, but any face covering at all is better than none.
It is vital that the best fitting and most effective masks are saved for those working on the front line, but now that there is no longer a shortage of such masks, the evidence for wearing properly fitted N95 masks in any indoor space where large crowds are likely to gather or where there is poor ventilation becomes more compelling.With the highly transmissible Delta variant, the need for effective masks in public settings is more urgent. The vaccines certainly do help reduce transmission and serious illness from the virus, but combined with other preventive measures, we can significantly reduce the spread of this virus further. Effective masks play a part in this, and it is worth investing in N95/FFP2 masks to replace your usual cloth or surgical mask. However, if you cannot get your hands on an N95/FFP2 mask then a cloth or surgical mask is better than no mask at all in preventing the spread of COVID.
When thinking of buying an N95/FFP2 mask, how well the mask fits is imperative. There is no point having a mask with a highly effective filter that does not fit around your face, allowing air and aerosol particles to move freely around the edges. It is also important that it is comfortable so it can be worn for long periods of time without causing irritation. There are videos available online for those who have bought these masks showing how to fit them correctly. People do worry about reusing N95 masks but we now know that the virus is less likely to survive on surfaces such as the front of a mask, so it is most likely safe to reuse them a few times.
Buying N95/FFP2 masks is not as easy as it sounds, with many counterfeit versions available and very little regulation. There is also no official guidance on exactly what N95/FFP2 mask to buy and where to buy it from, so it is difficult to distinguish between legitimate and counterfeit products.
It can be confusing knowing exactly which mask is best. The N95 and FFP2 high filtration masks outperform cloth and surgical masks both in studies and real-world settings when it comes to reducing the spread of aerosol particles – both for the wearer and for those around them.
Any face covering is better than none at all, but if you are able to get medical grade masks and wear them properly, then these are the right ones for you. If you opt for a cloth or surgical face mask, then ensure it has at least three layers for maximum protection.
