100 customers mention71 positive29 negative

Customers like the temperature of the respirator. They say it stays more cool than without the respiror attachment, has plenty of airflow, and the vent is helpful for keeping their face cool inside the mask. The exhale valve helps keep all the hot, humid air away from their face and fogging up their mask. They also like that the hot air is not trapped in there as badly as a normal mask, and there is not a bit of steamy build up within the mask, keeping the inside of the mask from getting too warm.

"...the vent was so helpful and kept my face cool inside the mask." Read more

"...first valved n95 and seems to be a bit more comfortable and cooler than traditional ones." Read more

5.0 out of 5 stars I use these for EMS responses and am very confident in them
Reviewed in the United States on September 11, 2023
Size: 10 Count (Pack of 1)Verified Purchase
So I don't have any peer-reviewed, RDBPC studies to back this, but I think these are very very good for both protecting yourself against airborne "stuff" and for protecting others from your exhalations. No, no, hear me out.

There is a lot of emotion about these exhalation-valve masks since the pandemic, but if you actually examine this thing, the exhalation valve is very heavily baffled. I'm not going to claim it's *impossible* to exhale physical droplets while wearing one of these, but it seems extremely unlikely just from the construction and from my own informal testing. (Try to blow out a candle through that valve from a distance of two feet, you'll see what I mean.)

Anyway, I have been an EMS responder for a long time, and this to me is an excellent compromise between wearability (what the review ratings call "comfort") and protection. As a small side benefit, the exhalation valve transmits sound better than the mask fabric, so you can make yourself understood that much better.

Anyway, they're cheap and highly protective against dust and airborne moisture, and I truly don't think they allow you to exhale any of the latter. If you really have to wear a mask for an extended period of time, you should at least consider these.

5.0 out of 5 stars If you are buying masks for yourself, and cost is not a concern, this is the one you want.
Reviewed in the United States on April 22, 2014
Size: 10 Count (Pack of 1)Verified Purchase
In terms of fit, dust leakage around the side of the mask, and durability this is a better quality filter mask than the ones I have used in the past.

The construction of this mask is a bit different from others of this general type. Most masks of this type have little depth. This mask is thick and has two part construction in depth. The surface of the mask is rigid on the outside. The interior of the mask is softly compliant. The springy exterior of the mask keeps the straps from pulling out, keeps the valve where it needs to be and holds the mask shape. The interior of the mask is soft, follows the curves of your face and wicks away sweat. The compliant, soft surface of the interior is perhaps the most important feature of the design both in terms of the fit and in preventing from dust from working its way around the side of the mask into your nose and mouth.

The breather valve has been added to reduce the effort in breathing through the mask. This is not the only function the valve has. The valve is positioned to guide your breath away from your glasses. This means that on cooler mornings that my glasses do not fog up. If you do work which routinely requires masks you will recognize this problem. Heat rises. With a mask without a valve my warm breath rises from the mask and fogs my glasses. The valve exhaust is positioned to prevent that. On all sorts of levels this mask has been carefully thought through both in design and construction.

By the way I have no relationship with 3M or any of its distributors. No one paid me to write this product evaluation. I appreciate the reviews written by others which guide me to better tools and more durable products, and help me separate good tools from cleverly packaged junk. I am returning the favor.
