Review: Great in comparison to Blueair 211+ - Based on a favorable review in Consumer Reports I purchased a Blueair 211+. I have returned that unit, and replaced it with an Alen Breathesmart 45i, so this review will be a comparison of the two. Both are approved by the state of California as not producing harmful levels of ozone, sometimes a side-effect of ion generation. Both units have ion generation, but on the Alen you can turn it on or off. I found the Blueair caused increasing eye irritation over several days, which I have not experienced with the Alen ion generator turned off. While the Alen is a bit more expensive (depending on the confusing filter choices on the Blueair), it also has a greater square footage capability. If you like the Alen features, you can get most of them at a lower cost in the Breathesmart Flex. Here is what I prefer in the Alen 45i. As mentioned, you can turn the ion generator on or off. It has a five color indicator for real time air particulate level, which I have seen change when I clean up a dusty room or empty a document shredder into a waste container. You can set the fan speed to auto, which will change the speed based on the detected air quality. It has a TrueHEPA filter rated at H13. This compares to the HEPAsilent terminology of the Blueair, which you can find criticism of online and which I noticed you can see through when I returned the unit. The Alen has multiple, easy to use lighted controls, and you can turn the light level up, down or off. If this review sounds like a am an Alen salesman, I am not -- just a retired consumer with no involvement ever in the industry. As to the Consumer Reports ratings, the Blueair is recommended as is the Alen Breathesmart Classic (which is larger and older than the Alen 45i). They did not test the newer Alen 45i. In real world use, I find a slam dunk favorite in the Alen Breathesmart 45i compared to the Blueair 211+, both in results and its' much greater user friendliness and flexibility to control.
Review: Immediate benefit of cleaner air! - I live about 2 miles from the beach and get a lot of dust and pollutants thru bedroom window because I need it open to cool the room in the summer. With this air cleaner running manual setting level 2 (of4) we find we sleep much better. This air cleaner has an app which I use on the iPhone. Only function it does not do is turn the control panel lights on / off. The app allows you to customize schedules and manipulate all other controls (power, mode, fan level) and see air quality. My room gets so dusty I have to vacuum the outer filter of dust every few days. The other day we had a skunk smell come in but the smell was gone with minutes! Very nice air cleaner.

### ⭐⭐⭐⭐⭐ Quiet
*by J***Y on October 22, 2023*

I’ve had a lot of air purifiers through the years and this one is far superior than any I’ve ever purchased. Not only is it sleek looking but it is quiet so I can sleep. The lights on the air purifier is not obnoxiously bright like some. I wish I would have purchased this years before!
