My wife has serious allergies to dust and more. After turning on the BreatheSmart 45i air filters she noted a big change and felt much better. We have used many different air filters over the years and I would say these are the best and recommend them to anyone.
I bought this for my 2 car garage. My mother moved in with me and she smokes out there. It is an insulated garage with 2 small doors and one large garage door. This thing doesn’t help the smoke at all. It is always on purple (the worst color). It runs nonstop and does absolutely nothing to help clean the air. I’m so disappointed.
We have had a 45i running at our house for about a year, and the unit has not been disappointed in any way; the air in our home is clean and free of all the particles that made allergy flair-ups commonplace. We just purchased two 45i's for our business, and only after a few days, our employees noticed a difference. These units are quiet, and although they may be expensive, they are worth every penny.
The 45i is amazing. It reacts to me lighting a candle in less than a minute from the room next to where it is. It's a distance of 20'. The 45i has made a positive difference in the air quality in my home, and I am grateful!
