A method of providing oxygen and/or a nebulizing treatment to a patient is disclosed. Modifications to a mask may include: adding nose cushion to increase conformance of the mask to facial features; covering breathing ports with viral/bacterial filters; and adding desiccant material to capture moisture accumulation. A face plate fitted over and working in conjunction with a mask which pushes the mask against a user's facial features to assure a better fit. Straps are disposed on the face plate, rather than on the mask. The face plate may provide or comprise: filter protection from user contact, strap locking features, and a nebulizer cutout.
