Cover the mask with my hands breathe out hard, breathe in hard. I would keep wearing Powecoms but I cannot get nearly as good a fit around my nose and the 9205/9210 nose wire is excellent and all but eliminates glasses fog.ĮTA: I do a fit test as described in the 3M instructions. I just got them so haven't tested the durability but the material is better and should be much easier to tighten a stretchy strap on these without messing with the staples. I opened the staple and reaffixed it but not great and the extra stress on the elastic obviously makes it more prone to snapping in use.Īnyway, I just bought some 9210+ which has an elastic vs rubber band strap. I tried to tighten the 9205 strap by tugging it through the staple. I don't think I even got 15 hours on my first 9205 because the on/off wears the elastic. I usually only wear a mask for an hour or so at a time and with Powecoms I can easily get 40 hours though I would need to tighten the head straps with a wee knot or a silicone strap adjuster.

I start to lose seal after two shifts with those while my powecoms actually fit better on day 2." Pre-stretching the straps on the 3M 8210 Regarding the 3M Aura 9205+, /u/thatjacob adds: "The headbands on those are kind of terrible if you take the mask off more than once or twice. u/jjcityscenes writes that, compared to the 3M Aura 9210+, the 9205+ has "rubber band straps which are not as durable/can break easily if re-used". Unfortunately, even if the user seal check seems to pass, this isn't a perfect guarantee that the mask still fits you well. If you feel a gush of incoming air around one of the edges of the mask, something's wrong. If you feel a slight vacuum inside the mask, this is good. To do this, breathe in suddenly and sharply.
