About this deal

The Vita Group said its face covering had been tested at external accredited testing facilities which showed filtration levels of more than 90%. It said that the discrepancies in results demonstrate the need for mandatory overarching standards to be put in place. We have been in discussion with the Vita Group and we are working together to understand each other's findings. Even so, the CDC, the World Health Organization and others health authorities, have emphasised that both washing one's hands, along with cleaning and disinfecting frequently touched surfaces daily are key in preventing Covid-19's spread. The CDC's latest guidance for how schools, restaurants and other public places can start to reopen details the need for intensified cleaning and disinfection of frequently touched surfaces such as playground equipment, door handles, bathroom taps and drinking fountains. It also admits that scientists are still learning about exactly how the virus spreads. So, although we still don't know exactly how many cases are being caused directly by contaminated surfaces, experts advise exercising caution. The researchers at NIH, however, did find that copper surfaces tended to kill the virus in about four hours.

We repeated the filtration tests after the masks had been through the wash five times, and gave equal weighting to the pre and post-wash filtration score. In our second round of tests (May 2021), we included newer-style 'semi-reusable' face coverings, and ones with higher-spec filtration claims and antimicrobial properties. This can lead to your face covering becoming damp, which reduces the filtration efficiency. This is why we only gave top scores to face coverings which got the balance right.But measuring bacterial filtration efficiency allows us to get an idea of how well face coverings provide a barrier for particles. It means that the virus circulating in unfiltered air conditioning systems will only persist for a couple of hours at the most, especially as aerosol droplets tend to settle on surfaces faster in disturbed air.

It should be noted that coronavirus particles can be much smaller (as little as 0.1 micrometre in diameter), so what we are measuring is not the face covering’s ability to protect against coronavirus, per se. Every time I walk in my home, the first thing I do is… wash my hands and then wash my glasses,” Horn said. Use soap and water to clean glassesClearcoat lets you define a layer of varnish or lacquer for a material – think varnish over wood, or the final coat in car paint. It has its own independent reflectivity, its own independent Bump map separate from the Base layer, and Absorption parameters that control how it colors the Base layer beneath it. Seven masks (results listed in the table above) failed our tests. We shared our results with the manufacturers or retailers, and these were their responses.
