45i review
on July 22, 2023
Posted by: MIA F.
The 45i is a fantastic unit, not only in size but effectiveness.
The 45i hits that sweet spot in term of its effectiveness, without standing out in a room.
Noise level on the 45i's is very quiet, even on Turbo mode.
Bought 2, another one for the house, and one for an elder relative that lives in a retirement home. Bought that unit (45i) for their room with a VOC/Smoke filter (extra carbon) to filter out retirement home smells. That 45i has made a difference in the air quality within their individual room, and the unit on Turbo/constant has not made a noticeable sound disturbance for them.
It's in my opinion, just the right size; had bought the larger 75i last year - 2022 but returned it for a 45i machine. Love it, bought 2 more this year.

The 75i is very large, bulky, and difficult to lift or move about. Too heavy in my opinion (I returned it and bought the 45i).
Separately we also own the T500 towers for the bedrooms. T500 towers are LOUD (sound wise) compared to the 45i's but doable for now. I may eventually buy 45i's to replace them; just due to the noise levels on high for the T500.
With all that said I highly recommend the 45i for size, noise levels, and effectiveness in clearing, cleaning the air quality.
*One suggestion I read from someone else was they should incorporate a "Lock button" on the model units designs. A lock feature, your settings stay locked it, lights aren't accidentally turned on in the middle of the night by a pet cat walking across it, etc.

Sneezing Less
on July 24, 2023
Posted by: Jennifer H.
I purchased this mainly to get in front of smoke season here in the PNW. What I also found is I sneeze less than I used to. I didn't notice really till a few weeks down the road, but it's been nice. Unit itself slightly larger and cheaper cover that I was expecting, but overall feeling good.

Excellent Air Purifier
on July 27, 2023
Posted by: Willy S.
I like my BreatheSmart 45i. The air quality indicator is a very nice feature, especially when use in conjunction with the app to compare to outdoor air conditions. It is very quiet running in the lowest setting at night and has a very sleek and modern design.

The BreatheSmart 45i True HEPA
on July 27, 2023
Posted by: Barbara K.
The BreatheSmart 45i True HEPA Air Purifier has been amazingly efficient at purifying our air during the recent smoke Covering our area from the Canadian wildfires. When our outside breathing was impacted by the dark layers of smoke the interior of our home remained clear and pleasant. We have several of these purifiers… this new addition is in our bedroom. It is absolutely quiet despite running it in high during the worst of the infiltration..if you are thinking about it, don’t hesitate!!
