In our tests, we found huge discrepancies in how well face coverings were able to filter bacterial particles. Our tests revealed that some reusable face coverings can do a good job of filtering particles, while being easy to breathe through. But others struggle to get the balance right. One of our testers rated each mask for how comfortable it was to wear with glasses and whether their glasses steamed up while wearing it. Ultimately, glasses and masks don't mix - so none of the options are a magic solution for spectacle-wearers. But some are much better than others.

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. 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. 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.Maskari said its mask has been tested by Swiss labs, revealing good filtration results, and has been approved as a community mask in Switzerland, so were surprised by our results. It noted that its masks are treated with antimicrobial substance, that Which? tests do not take into account. I’m certainly not saying glasses are the main culprit by any means, but you just always want to be careful — making sure you’re cognizant of the fact that glasses can transfer (the virus) and be aware of how to clean them properly.” 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.

Reusable masks aren’t required to conform to specific standards like disposable masks are, although there is a voluntary standard in place, which is why we tested them during 2020/2021, when they were being recommended as a community health measure.
