We have a two level 2500 sq. ft. home in Napa and we purchased 2 of these to clear our home of the smoke from the ‘Camp Fire’ that destroyed the city of Paradise California.
The AQI was somewhere between 150 and just over 200 for over a week. These accurately changed from Purple, to Red, to Orange during that time and our house was very comfortable with air quality. Now that the air quality improved consistently to an AQI well under 50, these two filters remain on Blue or Green throughout the day.
Since my wife if terribly allergic to our dog and our cat, we’re going to continue running them throughout the day as long as windows stay closed due to rain or cold weather.
We’re very pleased with the look, quality, and customer service. We would recommend the 75i.
I have several Alen filters and think they are great - which is why I was excited to get the 75i. I was hopeful for the better life of the new filters. But the control panel on the new 75i is a mess. Alen should stick with being an air purifying company. I recommend the regular breathesmart.

Hi Eric! I'm so sorry your unit was received defective! It seems there were a few bugs that needed to be worked out, but we've made some significant improvements over the first batch of 75i units that went out and are happy to replace that for you! Please feel free to give us a call at 800-630-2396 if you would like us to do so!
Have not seen too much improvement with sinus allergy yet but are hopeful. When on high,it does make more noise the the 45i but that's probably due to it being a bigger unit.
We bought it during the fires in California. Our breathing improved dramatically in 2 days. Now I'm glad we have it to filter dust mites and other allergens until we hit the next fire season again.
The BreatheSmart 75i Air Purifier is the second unit that I purchased within the past few months. I owned the 45i which we put in our Master Bedroom. The difference both have made in the air quality is unbelievable. We have pets who shed and it has made a tremendous difference in the amount of hair floating around and on the floors. The air smells so clean, which I'm sure it is compared to without the purifiers. We placed the 75i in our open family room/kitchen area. I definitely recommend and would purchase again.
This is the second product I’ve purchased. We have one in our bedroom and the new air cleaner in our family room. I had s little trouble at first getting it to stay on. Adjusted the filter and no problem since. Allen is a good company. I purchased purifiers for my daughters as well in past years. They love them too.
