What kind of face mask is best against coronavirus?

Do we have to wear face masks?

Unless you have a particular health condition, have a disability, or under a particular age, you absolutely have to wear one. There are exemption badges for those who feel that they are comfortable showing they don’t have to wear a face mask, but that is more of a personal decision.

Although everybody in Northern Ireland, Scotland, and England has to wear a mask or any face covering while on public transport, those with breathing problems, young children and disabled persons are exempt.

In England, all outpatients and hospital visitors must wear any form of face covering.

Does the type of mask you wear matter?

Yes, it matters. Different variations of masks offer different protection levels. Surgical grade N95 respirators provide the highest protection levels against Covid-19, followed by surgical grade masks. But these types of masks are in limited supply, expensive, contribute to landfill waste and can be uncomfortable to wear for extended periods. With this regard, countries that have mandated the public to wear face coverings have suggested that such masks be reserved for those at high risk or health workers.

Here is a highly reliable source to buy n95 facemasks from. 

When it comes to the protective value of reusable cloth coverings or single-use paper masks, the evidence is less clear but suggests face masks reduce Covid-19 transmission. Royal Society analysis stated that this includes cloth face masks that are homemade.

Is a cloth mask OK Are paper surgical single-use masks better or?

Outside of surgical masks, evidence on mask usage is still surfacing: there seem to be some advantages, but the precise parameters of the best face masks to wear and the extent they safeguard the wearer or those surrounding them are being figured out. It can be better using a tighter fitting, but the US Centers for Disease Control and Prevention (CDC) recommend that any face covering, including a bandana, is better.

A US research study found that household materials removed particles of – microns in diameter, which is the standard size of bacteria and viruses and made a conclusion that good options included heavyweight “quilter’s cotton”, vacuum cleaner bags, or multiple layers of material. Bandana material and scarves proved to be less effective but captured a portion of particles.

How to take the mask on and off safely?

Before wearing a mask, make sure you have cleaned your hands properly with water and soap. Cover the nose and mouth with the mask and ensure that there are no gaps between the mask and your face. While using it, don’t touch the mask, and if you do, make sure to wash your hands. When the mask is damp, replace it. While removing the mask, use the elastic tags to take it off, without touching the front part and dispose right away into a bin or, if the mask can be reused, put it in the washing machine.

How often do you need to wash masks?

The CDC suggests that they should be washed after usage “routinely”.

Is there an environmental concern?

Most of the masks that are available commercially are made from plastic layers and are meant for single-use. University College London scientists did an analysis and found that if each individual in the UK used a single-usage mask for a year, it would lead to the creation of an extra 66,000 tonnes of contaminated waste. The UCL team that is chaired by Prof Mark Miodownik suggest that if the general population used reusable masks, it would adversely minimise plastic waste and climate change impacted by any policy requirements. They said reusable masks do most of the work single-use masks do without the waste stream.
