My old one served me well for 6 years. This new one blows my mouth open and dries it out. I had it back to my pneumonologist and he turned it down slightly so it didn't blow off the pillow case. If I had control I'd go back to my old settigs and be happy again. Old one was 4.1 and did the trick.
My five stars is because for me there does seem to be a distinct difference from the standard filters. Pollens and dust out here in the western part of the country does a real number on my nose, so any improvement is good. The S9 filter might be an answer to those uncomfortable nights.
AirSense 10, AirCurve 10, and S9 Hypoallergenic Filter
Very prompt customer service to customer . Also works great with my machine .
It's worth paying extra for hypoallergenic filters than the cheap ones. I live in a urban dusty area, so filter are a must for me.
