These filters are easy to fit and use - they are layered and are really comfortable to wear under the mask. Very happy with this purchase and have bought these previously as they are so good
Fir perfectly in the mask as designed. Great experience of regularly wearing the mask and replacing filters without issue.
This company makes best anti-Covid masks I have yet found and the accompanying filters are similarly of the highest quality. People have asked me 'where did you get your mask?'
I’ve been using the People’s Rainwear mask for about a year now, and I’m very happy for it and the KN95 replacement filters are good.
