This is a non-disposable face mask using a gel seal and a disposable, replaceable filter. It come in one size that will comfortably fit most adult faces.
Filters are individually wrapped to provide a clean, electrostatically charged filter for installation prior to each use. Mask and filters are NIOSH N95 rated.
This unique mask with its individually wrapped filters allow you to take the equivalent of several disposable masks with you in one compact package.
Note the filter only treats the air you are breathing in. It does not filter the air breathed out. If you are trying to protect those around you from your coughs, you will need to also wear a surgical mask or bandana over this mask.
