Purchased this unit for my wife’s bedroom as she has problems with allergies. Seems to be helping although there seems to be no rhyme or reason for the changes in the fan speed while in auto mode, I must assume they are justified. I like the prefilter as it seems to capture a lot of dust and dog hair. I vacuum it off every 4 to five days.
As recommended by Dr. Ben Lynch, Alen Air Purifiers are the BEST! We upgraded our model this year and are so glad we did. The BreatheSmart 45i True HEPA Air Purifier is beautiful, quiet, and effective. We literally breathe deeper knowing our air is safe!
I have had this only for a few weeks but love it - just as I have loved the BreathSmart Flex unit I purchased in 2020. I moved into a slightly larger unit which required an additional purifier. I researched air purifiers extensively before buying and the design and build of these did not disappoint. The fact Alen is based in the USA and provide a great warranty also factored into my purchase. Very satisfied.
The Alen BreatheSmart 45i that we purchased has been working fine since we unpacked and started it. We can tell the difference in our Family room where we have it running. The unit is so quite we hardly know it is on and working. We really like the color ring that shows us when the air quality has changed and keeps us informed as to how long it takes to adjust the air quality, great feature. We also like the Ionizer that helps remove airborne particles that we would eventually inhale. We would recommend this product to anyone who is concerned with the quality of the air in your living environment.
