Hi
New to this group but a member of others for immune conditions. I have manage to survive the last 3 years of the pandemic, but came down with COVID on the 26 Dec, only now, 12 weeks later have I tested negative. I always use a N95 mask when outside, but have seen this product, and I wondered what the thoughts were on this?

With the HEPA filter it claims to screen viruses and bacteria down to 2.5 micron. Which is smaller than the COVID virus particles (I understand).
