I recently moved from the southwest to the south east. My allergies are so bad. This air purifier is the best! I had a big huge one before that worked well but was so big. This purifier doesn't take up much room at all. It's very quiet.  It has a led display for the controls which also tells you the quality of your air. I baked salm9n for dinner and within 30 minutes of us eating, you couldn't smell fish at all! My house doesn't smell like a hospital but it certainly smells clean. I have 2 small indoor dogs and 2 teenagers, before my house always smelled a little.  Now when I get home and walk in, I don't smell anything.  My allergies are so much better after only a week of using this purifier.  I 10 out of 10 recommend!
