Optrel Swiss Air Half-Mask PAPR 4700.010

Spendy but worth it

Works great, little apendy but worth it.

Many flaws, but works well when it works

Here are my complaints. 1. Filter pack is hard to change without breaking the plastic retaining tab. 2. On off switch is just that, it is either on or off, not fine adjustment like it leads you to believe. Sometimes I get it all on (which takes a few minutes) and it will not turn on. I then have to take it all of and remove the battery sometimes multiple times before I can get it to work. Now I turn it on before I get it on my back and on my head. 3. In freezing temperatures it seems like it will not work. I have to bring it inside to warm up before it will work. 4. Pre-filters are cheap, but the main filter is pretty expensive at around $50.

So comfy and does the job well!
