If we don't have allergies, do we need an air purifier?
Everyone benefits from improved air quality in the home.
Will this work if we have vaulted ceilings?
Look for models with vortex action (exclusive to Vornado products) which will circulate the air throughout the entire room, including high spaces.
Should I keep this running constantly?
During allergy season, it's best to keep it running 24 hours. Obviously, factors such as open windows, pets and smoking will dictate your decision. If these are the factors in your home, you will want to run your purifier constantly for maximum effectiveness.
How loud does it get?
At its highest level it sounds like a big fan, and at its lowest it's barely noticeable. This is the recommended level during sleep time.
