The 3M HEPA Mask is a high quality HEPA mask at a very attractive price.  It is reasonably lightweight and comfortable.  Some people find the head straps a little stiff.  For someone with very severe allergies or asthma, or someone who will be in a place with a substantial amount of an allergen or other contaminant, the 3M HEPA Mask is a very effective solution.  Plus, at $21.95, it is very reasonably priced.
