Masks are great!! But use a filter.
Masks are great!!! Though you MUST put a filter in them. Pros: Light-weight. Really like you are wearing nothing! Not too large like some. Nose clip, adjustable ear strings. Easy pocket for filter. Inexpensive!!! Cons: So thin, not effective w/o the filter. Wrinkles terribly after washing.
