Helping with my allergy!
I've had this lying around unused for 5 or more years.  I bought it because I'm immune-compromised and had chemo and worried about germs while traveling.  I ended up not using it much but recently, with COVID-19, decided to plug it into our family room, the room we go through and are in the most.  I have had allergies and over the past 10 or so years have had to blow my nose frequently even when I'm inside.  I have no way of knowing whether this device will help against the virus, but, to my surprise and delight, I realized recently that I have hardly ever had a runny hose anymore when I'm in the family room.  It has really helped relieve the inconvenience of my allergy.  The noise is very white -- just a steady sound of air blowing, and it's not at all obtrusive.  We'll see how long it lasts before a bulb or something else wears out, but for now I'm delighted.
