My reservations of the Alpine Living Air Purifier (even though I own one) is based on the danger from the ozone it creates and the fact that many people get one for allergies, despite the fact that it does not collect dust or pollen. Alpine Air is now sold under the name Vollara (hence the Alpine Living Air Purifier is not manufactured anymore). It has been a Network Marketing product, which accounts for the price. I originally knew it as Alpine back in the 1980's.
If you're curious why it changed names from Alpine - to Ecoquest - to Vollara it's because of the Ozone problems and the government being on their case about that and over-the-top claims about what it could help. The name changes allowed them to operate when lung problems occured. Simply put high levels of ozone can harm/irritate lungs. The video below explains the pros and cons.
What I love about my Alpine Living Air Purifier is the ozones ability to kill mold and odor when I need it. It's the best technology for these 2 problems. As I said before it won't removet dust or pollen. I use it to "shock treat" a room to make the room "sanitary". My day-to-day air purifier (the Alive Air Purifier reviewed on this site)runs 24/7 and uses negative ions and HEPA to remove dust and pollen.
MY SHOCK TREATMENT RECIPE: Every month or so I crank it up and leave it on in a room for several hours. I leave the room closed, or leave the house. Then I shut it off, open the door (or windows) and let the remaining ozone dissipate for several hours before I go back in. I use it for my bathroom and on an occasion when I have a mold or odor problem (kitchen, garage, or basement).

Even so - I like my Alpine Living Air Purifier Air Purifiers for mold and occasional problems with mold and mildew. I don't use it everyday, and I don't put it ahead of my daily air purifier which uses Hepa, UV, negative Ion, & Carbon air purifier.
If you're looking for ozone for mold and odor removal there are also smaller, less-expensive Chinese ozone air purifier models available (some for $100) which will do just as well.
