Review on 🎭 Advanced Activated Meltblown Non Woven Respirator with Replaceable Filters by Mark Powell

These filters are a great idea for extra protection. A filter is not always needed, but when it is needed it should comfortably cover your mouth and nose. These type of disposable filter cartridges are VERY SMALL for my adult masks. The best-fitting adult sheet masks require a larger filter than this style, which appears to be a standard size. Best for small children.
