My allergies are so much better
I was lucky enough to snag these for major savings on Prime Day this year.  And, i finally had my 'a'ha' moment last night.  I had been at an outdoor concert for the evening and my nose had a constant drip all night.  Just 5 minutes after getting home and breathing in my clean air, it stopped!  I'm snoring less and waking up less congested!  Some folks complain about the noise, but I only notice the low hum when I'm sitting completely motionless in silence.
