These face masks are a great solution. While N95 cannot be replaced these are great for quick errands, mowing the yard, getting gas and more. They can be easily wiped cleaned or sprayed after use. The filter can pop out in seconds and you can use many items (some you may already have) as a replacement filter. We are printing our mask out on 3D printers using PLA or PET (extra cost) filaments. The mask can be heated with a hair dryer or heat gun to adjust for a tighter fit. We sell our mask assembled including elastic straps, rubber seal and a starter filter (you can decline filter). You can also purchase just the body and construct your own mask if you want to save a few dollars.
