3M 8511 Cool Flow N95 Mask, Valve Respirator, Stretchable, White, 2 Pack

These are the best all around particle masks that I have found. I use them in attic, under house, mowing the grass, cleaning out dusty barn and garage, sanding, working with fiberglass insulation, hauling or turning moldy compost or wood chips. The one way exhale valve helps prevent rebreathing expired CO2. That feature helps minimize any feeling of air hunger/dyspnea when I am physically exerting myself especially when pushing the lawnmower.

I liked the price of the items and the fast shipping speed. I needed these masks for cleaning and they did a good job of preventing me from breathing in any dust or particles. The masks were tight and there were no air leaks. They only thing I didn't like were the marks they left on my face, but I consider that to be minor. Overall I would buy more masks like this.

I have asthma and breathing problems since COVID , so I have to be extremely careful with any paints, chemicals etc. I sprayed Tilex and with this mask, no odor passed into the mask. Had no problems breathing afterwards. This is my " Go to" from this point on.

This was a great mask thick you felt protected but the placing of the bands around the head are uncomfortable, so I remove them and then I replaced it back as ear straps versus head straps

I have feral cats living in my garage, (with litter boxes) but I'm allergic to cats and dusts and just about everything, so I got these because I clean out my garage 2xs a yr., spring and fall. These worked great for that purpose. I'm patting myself on the back for thinking of doing this because it saved me days of allergy issues.

Thankfully I have not used these in a critical situation. However I have used them in our extremely large 5 acreage lawn that we mow and I am comfortable doing this for several hours at a time. I've tried several kinds of N95s and these suit me well

I recently moved into a house where the previous homeowner had not mitigated hard water for six years. I was cleaning the tub with CLR and lime away, which are both very strong. In order to protect my lungs from the smell, I chose these facemasks. They worked for the intended purpose, but were so incredibly tight across my nose that I had a bruise the next day after wearing the mask for four hours. It worked for its intended purpose.

This mask works great for mowing the lawn especially in high traffic areas of geese with their droppings. It allows enough ventilation while mowing and keeps out the allergens, dust and other harmful particulates etc. Very comfortable as well. I highly recommend.

Too tight, I mean the elastics are too tight

Much too large for a female face. It drops about 3/4" below my chin, so I don't know how this mask would keep anything away from being inhaled.
