Review on Knitting Factory Covering Washable Replaceable Occupational Health & Safety Products and Personal Protective Equipment by Adam Hardy

I have other masks that use filters. They are sewn with a small hole through which the filter is inserted. They have an adhesive that sticks to the mask, which doesn't really work. In addition, it is so large that it hangs over the mouth and chin like a curtain. Disappointing considering I bought it on purpose thinking it would be thicker than regular masks. I can't use it at all.
