Abstract
A facial mask for filtering ambient air is formed from a pre-form of a multilayer flexible flat filter member of a size to extend over the mouth and nostrils of the user. The flat pre-form filter member can have an ovoid perimeter with an endless band of a hypoallergenic adhesive tape encircling a perimeter of the filter member and operable for sealing with the user's skin to prevent leakage over extended use. Portions of the adhesive tape can self-seal during a sizing step to form structural paths for maintaining a central concavity to ensure a large filtration area offset from the nostrils and mouth of the user. The flexible filter material can further include an activated carbon layer.
