We have used the Alen 75i for four weeks of constant operation during the U.S. Air Alerts this summer. We could tell the difference in our large family room within one hour. Alen advises to let it run constantly! So: four weeks later the purifier is still quiet, still efficient, and we depend on it.

Really does the job. Both myself & my little Beagle girl are allergic to grass & weed pollen. I have two 75i's in the house (single story 2860 sq.ft.) and they truly help. I live in the mountains of Idaho, so forest fire smoke, dust etc. are an issue. The 75i takes care of that as well.

Alen BreathSmart 75i is a great addition to my family room. We recently had a wildfire near our home, and it kept the air in our house clean and fresh.

We had been considering a air purifier for some time, but as it happens we did purchase the 75i during the ongoing Canadian wildfires and resultant poor AQI. I am glad we did. The color monitoring definitely provided feedback on air quality. Had we not purchased it our indoor air quality would have been comparable to the outside haze.
