The Airstream is a great respirator that doesn't take up a lot of space. I had to purchase one for myself because my work wouldn't, but it is completely worth it. (Posted on 3/21/2017)
Great for woodturning dust protection Review by Terry McCammon

I am a woodturner and use this whenever I turn or sand. I can't smell anything so I presume it is working fine. I have had no incidents related to breathing wood dust. They are expensive, but the alternatives that I found were not as effective. (Posted on 9/5/2015)
Review by Heidi
These helmets are used in our quarry and unfortunately the motor design is less than effective, they have exposed bearings and this means that when the helmets are worn in the production area which is of course very dusty they break down very quickly, defeating the purpose they were intended for. We have had nothing but trouble with the units and the parts are very expensive-not to mention the unit itself. (Posted on 5/31/2012)
Review by Steve Schlumpf
I am a woodturner and used the Trend Airshield for a few years but was always concerned that I could smell the wood. I figured if I could smell it - I was breathing it! Finally upgraded to the 3M Airstream and love it! I find the Airstream comfortable to wear and like the idea of having the battery on my belt and not in the headgear! Also like the lock-up face shield and the added protection that the helmet provides! (Posted on 2/9/2010)

This unit works great and Enviro Safety Products shipped it promptly. All in all, I am very satisfied. (Posted on 1/30/2009)
Review by Scott Cornett
Good fresh air respirator unit. I just think it is on the expensive side. I would buy them for more of our employees if it cost less. Those who have them love it. (Posted on 2/26/2008)
Review by John Schrader
I bought the 3M Airstream after being disappointed with the Trend Airshield. I use this for wood turning and this unit is of commercial quality. I use it on a daily basis with the earmuff kit and I have not had any problems. It blows plenty of air and the faceshield does not fog up. A great powered respirator for wood working.

Review by Steve Bryant
A great PAPR unit for the dustiest conditions. We bought these for our guys that "sweep" almonds and this is about the harshest dust storm you can find. Our guys are work harder and safer, I only with I would have found the 3M Airstream sooner. (Posted on 2/26/2008)
