A combination mouth and nasal mask (40) for assisted respiration or CPAP is disclosed. The combination mask (40) has a frame (42) to the rear side of which is mounted a separate nasal cushion (44) and mouth cushion (46). Both the nasal cushion (44) and the mouth cushion (46) separately form a rolled edge seal around the patient's face in the vicinity of the nose and in the vicinity of the lips. Inlet air is communicated from within the housing (48) to the mouth chamber, circumscribed by the mouth cushion (46) by means of one or more interconnecting tubes (62). The proportion of air communicated to the mouth chamber (48) is controlled by the sizing and number of the tube(s), thus providing for free flow of air, restricted flow of air and pressure equalization, or zero flow of air. A mouth mask (10) for assisted respiration or CPAP also is disclosed.

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.
