Great investment

I LOVE this thing. My mother is now staying with me due to health issue and she is a smoker. She is not mobile, so smokes in the house. I bought this based on a recommendation from a friend. LOVE IT! My house does NOT smell like smoke. I run it on auto all the time. You will smell a bit occasionally until the auto detects it, bu then poof, gone!

Did not do what I hoped

This unit was recommended as one of the best for having in my cigar room. It really draws in very little smoke and actually had to sit next to it to notice any draw at all and still smoke would pass by. Maybe I expected too much for 600 dollars.

One month review

My husband and I found in a months time, that the MinusA2 air purifier does a great job. It is exceedingly whisper quiet on the lowest setting and not loud on the highest setting. Cleaning the filter once a month is very easy as well. I chose the pet filter and noticed a difference within two weeks. I would recommend this product.

Fresh Air Freshman

My son is a freshman distance runner in college. A week after moving into his dorm room, he and his two roommates started to not feel well. They thought something was wrong with the air quality. After visiting, we (The parents) agreed. Thinking it may be a mildew or worse a mold issue, we hired an air quality specialist to come and do some testing. After the results came back. We were thankful for the normal mold reading, but very unhappy with the heavy/high levels of cellulose and other particulate in the air. After much research we chose the rabbit air minusA2. The 780 model. (We wanted more air changes per hour) After the very easy set up. (10 minutes or less) we left them to their studying. Two days later we were called and told that there is a 100% difference in the air quality. We have not had the air retested, but if 18 year old boys can tell the difference, I see no need. Thank you to the incredible staff at Rabbit Air. They we kind, thorough and prompt. The product is great and the customer service is its equal. Thanks again... PS. Every dorm room needs one. My daughter will be getting one next year when she goes to college.
