Circuit Board Blue

Works great for XS size head. Fits snug on the face. I use these every time I go outside and double up with a cloth neck gaiter to cover up the air valves when going into Supermarkets or any indoor facility. N95-N99 filter and a cloth neck gaiter and some hand sanitizer will hopefully keep me virus free. I have six of these masks in various prints and rotate them out every two weeks (store in brown paper bag for two weeks to kill any viruses) and have been using them for the past two years of the pandemic. Highly recommended! Works great to help filter out air pollution as well!!! LA Smog be Gone! Good for hiking, cycling, etc...

I took a gamble on this one hoping that it would fit extremely large heads (7 7/8 or XXL / XXXL depending on manufacturer) and I'm happy to report that it works. This doesn't actually go around the crown of the head, of course, and I'm not the smallest guy in that area either. For reference I'm 6'4", BMI 35 (275lbs) and my hat size is 7 7/8. There's a pretty good chance that these will fit you.As far as how well they work I will give an update later. The fit is OK with my full beard, but a little bit tight. I have a bad allergy to Latex and I haven't noticed any issues there. I'm hoping this will give me a break when I'm around chemicals that give me a migraine. With the N99 and PM2.5 it should block those things. I'll do an update later when I have more experience.

like a few others, I had a serious issue with the initial fit of this mask. My far more brilliant wife, however, I was able to show me how to put it on properly and it is a very nice mask. I wear mine while cutting 2 acres of lawn and field, and I have far mild reactions to allergens. I can recommend this mask if you have somebody smart enough to help you put it on properly.

A bit heavy after prolong use, and not too uncomfortable. It’s bearable. It’s Velcro at the back, fitting over the ear by loop, but isn’t as secure as I would like, but it gets the job done. At the time my route took me by a lumber yard, and I didn’t like breathing in the smell/cedar etc. After wearing the mask a few times during the runs, I noticed it hindered my time due to the way of breathing while running, but it did lower the amount of cedar I took in, but decided to just wear it casually on vacation trips when on Greyhound or Flights.

Great mask! The most comfortable ones I own... good for active wear and very sturdily made. Good adjustable nose piece and face coverage. The only issue with this type mask is that when you exhale the vents/valves don’t filter that air... so if you already have Covid and are in a state of health where you could possibly pass on the virus you could infect someone. Since I have already had the virus and have antibodies that’s not an issue for me. I wear one because of regulations only... and to keep from becoming possibly re-infected. Either way, as an essential telecommunications worker this mask has met my needs well!

HANDS DOWN, this is the BEST respiratory mask I've ever worn. It forms a complete seal around my face and is VERY comfortable. I wore this outside for most of an entire work day and found it still comfortable to wear! The band goes around the lower part of the head, so it doesn't get all tangled up in my hair, which I can't stand with the simple dust mask with those tiny rubber elastic bands. In light of the Corona Virus, PLEASE STOP buying basic dust masks! They do very little to actually stop the virus as so much around your face is open. These mask form a complete seal around the face. The filter inserts need to be replaced every so often, but not nearly as often as the throw away masks!

The mask is all around great. It’s quick and easy to put on, their special velcrow works great. The replaceable filters are great, and easy to install/replace. The straps that go over your ears do cause slight discomfort, but I’m sure that differs person to person.Highly recommend.

I ordered the 2 pack but only received one mask with twice as many filters. Pretty disappointing. I ordered this pack for the yellow black mask, but received the blue only.Pretty tight fit around my head, tugged my ears down a lot. But it did work well while I mowed a dusty lot. Could be better but worth the money.
