Question: The air particulates in Los Angeles are measured at 2.5 microns. If your mask is only tested to 3 microns it will not protect  for 2.5 microns??micr
Document: These masks or very good if you have to clean a storage shed that might have rat poop in it and u can inhale and get all kinds of diseases from that so protect yourself! all these would be good if there was a outbreak of some kinda h1n1 or TB or influenza in the usa it will catch all the bad things so all your breathing is air as long as you keep it on
Good product to have around. I use it for lawn work, mowing, blowing leaves etc. We recently had a very unusual bad air day from wildfires in the area. The mask was very useful.
While visiting Beijing the last week in February, it was the worse air quality day in recorded history. This mask helped me enjoy the historical sites, which I could not have done if I didn't purchase them. Highly recommend.
I work in the medical field and these appear the be the same ones that are supplied in the hospital. They are of good quality and are very sturdy. They would be great to protect yourself from inhaling any fine particles such as with household renovations or to protect from airborne illness. I recommend these to have on hand just in case!
If you have low immunity or just want to protect yourself, these are great. I wear them on airplane flights to protect me from germs passengers may bring on board with them.These masks should not be crunched to maintain their effectiveness. I found a plastic lidded bowl that these fit in perfectly. So, when I pack them, they maintain their shape. And, they stay clean.
Wore this during the recovery after hurricane Sandy. Worked really well, when I took it off I was sneezing from the mold in 2 seconds flat, so this thing was doing a good job when worn. Its pretty easy on the nose too, the cheapo ones that the volunteers were handing out rubbed my nose raw.
These are very well made, too well, almost. I can breathe with one on, and it keeps everything out except air.
We really didn't need the stupid masks. It was a case of "overkill", too much precaution for the problem.I'm sure the masks are fine, but most viral or bacterial infections are passed by hand, not air.
I have allergy-induced asthma, and where I work, this is always a hazard. I can wear one of these masks for about 4 hours, and they do the trick filtering out a bacteria-based spray that is used in our facility. I go through 2 masks per day, so be sure to order a size that fits comfortably but snug - the adjustable nose band is great.
I do a lot of international traveling...a lot! This winter I will be going to Southeast Asia and possibly to China or India. Much of this area has pretty foul air. I rarely wear masks, but there are times!!! I can buy masks over in Asia, and they are cheaper, but the quality is often questionable, and they are usually way too small, especially when it comes to covering larger Western noses. These masks seem to be perfect!
