Hi BrighSpringbudSandpiper5105. I just thought I'd share my own experience with an air purifier. I have allergies along with my sleep apnea. I purchased 2 HEPA filter systems for my home, one of which is in the bedroom. My experience is that I have less allergy symptoms (stuffiness/congestion, etc.) which makes my CPAP easier to use. I've had them for a little over a year not, and I have noticed less dust in the room over time. Please let us know how it goes for you!
