How to make an N95a respirator-style facemaskface mask
As of today (March 31, 2020) there's a '''severe shortage of PPE''' (personal protective equipment) in the United States as we face the COVID-19 pandemic. Many people have been making masks at home in an effort to provide a minimum of protection to frontline healthcare workers, and some hospitals have begun accepting donations of these homemake masks.
I began making surgical-style masks at home, for which there are many online guides, but found them to be '''frustratingly uncomfortable''' and '''seemingly ineffective''', as they fail to form even a rudimentary seal around the wearer's nose and mouth. Instead, I decided to try and make a smaller, more comfortable, and potentially more effective homemade mask in the style of certain disposable Chinese KN95respirator-style masks that are available online (KN95 is roughly equivalent to the N95 specification in the United States).
This design has gone through several iterations and seems to work well. It '''uses less material''' than a homemade surgical-style mask, is '''more comfortable''' to wear (in my opinion), is '''reasonably easy to sew''' (even for a beginner like me), and it offers '''arguably better protection''' by eliminating any large air gaps.
== Warning ==
Please note that '''this mask has NOT been rated or certified''' in any way whatsoever. Its effectiveness will depend entirely on the quality of construction, the particular materials used, and how it fits on the person wearing it. Similar to manufactured N95 masks, thisThis mask should NOT be used by anyone with a beard. This mask may provide better protection than a bandana or a surgical-style mask, but '''it should NEVER be used EXCEPT when medical-grade equipment is UNAVAILABLE'''.
