It’s time to upgrade from cotton masks



With Covid-19 variants like the delta that spread faster, it is time to consider more heavy-duty masks than cotton masks and jersey face coverings.To get more news about quality type II mask factory, you can visit tnkme.com official website.

The US Centers for Disease Control issued double-mask guidance in February, a worthy guidance against new and dangerous Covid-19 variants. Physicians in India, during its second wave, also recommended either double masking or using N95 masks, especially in cities where infection rates had gone up to as high as 50%.Though the US had removed the mask mandate for those vaccinated in May, the CDC is now recommending that even those fully vaccinated must mask up indoors and in public spaces. This updated guidance comes in the light of a surge in Covid-19 cases in the US in the past few weeks, 92% of them attributed to the delta variant.

In densely populated countries like India, where social distancing is an economic luxury and often impossible, easing the mask mandate is not even an option yet. India’s own mask guidelines haven’t been updated since April 2020, when medical-grade masks were in short supply the world over and triple-layered cotton masks were a viable alternative. But that shortage no longer exists.
“Cotton masks may not be an effective solution to prevent the aerosol-mediated transmission in high-risk areas like hospitals, markets, and other crowded places where one cannot follow social distancing rules,” says Dr Merlin Moni, associate professor at the infectious disease division at Amrita Hospitals, Kochi. This also applies to spaces that are air-conditioned and not properly effective.
Moni says studies have shown that cotton masks protect the wearer by only around 50%, and a surgical mask is close to 60%. For this reason, N95-level masks—also known as FFP2 according to European testing standards—are recommended by doctors, especially in cities with high infection rates. These can prevent the transmission of airborne particles by 95%.

Whichever mask you wear, the key is that it should snugly fit the face, and cover your mouth and nose. A general rule is that if you are wearing glasses, a well-fitted mask, especially around the nose, will not make them fog up.

The trouble with N95 masks is that they are generally single-use and most of these cannot be washed or disinfected. While there is no consensus on how many times N95 masks can be used, doctors ideally say these should not be used more than two or three times at the most.

For this, doctors use a common hack, which was developed when there was a shortage of medical-grade masks. You buy five masks and wear one each day. The ones not in use can be kept in a paper bag. This way, five masks can be used for up to three weeks in rotation.

But for those using these masks regularly in crowded places, such as offices or shopping malls, doctors recommend reusing N95s only if they can be decontaminated.Ideally, an N95 can be reused up to three times after disinfecting effectively using either a hydrogen peroxide vapor spray, treating it with heat at 70 degree celsius, or by using UV light,” says Dr Sharad Joshi, principal consultant of pulmonology at Max Super Speciality Hospital in Vaishali, on the outskirts of Delhi. He does not recommend reusing these masks in hospital settings. Joshi adds that a surgical mask can be worn over an N95 to prolong its use.

Amrita Hospital’s Moni also suggests that UV chambers for disinfecting such masks could be a viable and sustainable solution for large workplaces to consider reopening. And yet, disposable N95s may not be an affordable solution for many in low- and middle-income countries like India.
