With chronic sinus and lung trouble worst in dry,cold air and have used many different facemasks for 35 years. The 3M 7500 with 2091 filter is so comfortable I wear it every day. Inside the mask is "little Hawaii" a plenum of clean, moist, warm air. My nose stays moist and nasal irritation and congestion are all but eliminated. At work and play, especially in cold, dry north wind, I am given a life free of sinus trouble with this mask.
As a cabinet maker in the mid 70's I learned the power of the binks automotive mask, charcoal with paper prefilters in preventing sinusitis. I found lighter weight masks for particulate matter.
The only time I ever did as well without a mask was living on Oahu for 18 months. Thus I dub the 6000 and 7500 "little Hawaii".

If you have to wear one, make sure it's comfortable. The upgrade from the 6200 mask is improved with a softer, better sealing silicone material, much like on a good quality dive mask. I used this mask while needle gunning steel hulls in the winter time. Not a very comfortable job to begin with, but the respirator made the cold dust and acetone fumes bearable in confined spaces. The dust ring around my face showed how well this mask seals. If you gotta wear one, don't skimp. Cheaper than a doctor visit!

I use mine for everything from sanding to spraying gelcoat. You know its a proper fit and really works when all you smell is nothing at all!
