This will be my final general review of the Brevida unless someone has some specific questions.
When using bilevel pressures the mask will do a bit of "modulation"...inflates a bit with inhale and deflates a bit with exhale and the more difference there is between inhale and exhale the more modulation you will experience.
It also will vary more with higher pressures and any exhale relief you might be using even if you aren't using a bilevel machine because when you use exhale relief you are creating a little bilevel situation.
If you ever tried the F & P Pilairo and found the modulation with it was too annoying...you probably won't like the Brevida even though the modulation is less pronounced than with the Pilairo.
I notice the modulation but it isn't all that annoying to me and disappears (meaning I don't notice it anymore) fairly quickly.
It isn't an issue for me but it could be for some people.
All in all I rather like the Brevida. The back strap still slides up occasionally and could stand to be a tiny bit tighter but I just haven't done anything about it because it doesn't do the sliding up all that often...it's pretty much like the P10 back strap which would also slide up the back of the head every now and then. Minor annoyance that didn't happen all the time.
If you get any condensation in the Brevida pillow...no way to get it out except remove it and clean it out. It just pools in the pillows and impossible to drain out back down the hose without a lot of fiddling with the pillow and hose. Might as well just take it off and clean it out...will save time in the long run. Found that out a few nights ago.
All in all I like the Brevida. Still haven't decided on its final placement in my list of preferred masks.
If you absolutely hated, hated the Pilairo...probably won't care for the Brevida either.
I did try the Pilairo and I was sort of bleh..it's okay I guess...but I didn't fall in love with it. So if you are more like me and not absolutely hate the Pilairo you might like the Brevida.
Now if you loved the Pilairo but found the overall footprint of that pillow on your nose annoying...you might really like the Brevida because it is going to have a much smaller footprint.
As with any mask out there...one man's trash is another man's treasure and in the end you simply have to try something to see how you feel about it.
NanWilson normally likes what I like but with the Brevida she just didn't like it.
No mask is ever totally perfect...we just have to weigh the pros and cons and decide if the good outweighs the bad and meets the bulk of our own personal preferences.
