Air Quality

Blueair Blue Pure 311 Auto
Auto feature is nice
I bought this air purifier before taking on a home remodel/addition project in anticipation of increased dust. In addition, I have cats and dogs in the house so figured it would be useful in general. After some thorough research on purifiers, I went with Blueair and am happy I did! I love the auto f...

Dylos DC1100 Pro Air Quality Monitor
Would using a smart outlet to turn off my purifiers when not in use to help extend the life of the filters?
But to do that you need an accurate meter. I've got three purifiers that I rarely need to use based on PM levels. I currently use a Dylos 1100 pro but will soon be testing P. urple Air units. I try to keep pm2.5 levels below 2micro grams/m3 , and find this easy to do with infrequent use of my purifiers.

Broke after 2 months
I bought this back in March. Most amazing air cleaner I ever owned. However it stopped working in May and it's now June and the company had not fixed the situation. I'm very upset and suffering allergy season with No Air Cleaner. Way too expensive to last 2 months. Will update if/when they rectify t...

Dylos DC1100 Pro Air Quality Monitor
A very useful device for asthma sufferers
I purchased an IQAir Health Pro Plus a few months ago after suffering from a bad bout of bronchitis. I developed a variant of asthma which leads to coughing excessively when the air quality is poor. The IQAir has been a great addition to my home, but it bothered me that I had no scientifically objec...

Pollutant Reduction

Blueair Blue Pure 311 Auto
Looks great, poor performance
Too bad the performance of the air purifier doesn't match its styling. We like the look of it but for our house it just doesn't perform well. We have neighbors that smoke A LOT of marijuana and unfortunately the smell is mainly coming in my sons room. This model (311) does very little to get rid of ...

Effectiveness

It works!
We ran this air purifier in our family room all night on low the day we received it. A usual, my husband went into the family room early the next morning to read the news, and for the first time in months did not sneeze and cough for 10 minutes. We don't even hear it. Just leave it running at low sp...

Ease Of Use

Blueair Blue Pure 311 Auto
Auto-magic, but hates popcorn
Had a laptop overheat and it was full of cat hair, so decided dusting alone was insufficient. Got the Blueair Pure 411 because it looked like it: would wrangle excess fur balls, quietly disappear into the background, and is “set it and forget it” automatic. It’s been deployed for duty in my living r...

Energy Efficiency

Blueair Blue Pure 311 Auto
The newest version (2021) of the small room purifier
This is a step up from the old versions with an air sensor and auto settings. The fabric off the prefilter is a lot thicker and is easier to put on and take off using velcro compared to the old 411. The old prefilter was a cylinder shape that was stretchy and very thin and seemed like it might tear ...

Dylos DC1100 Pro Air Quality Monitor
I can not believe how wonderful this product is
I can not believe how wonderful this product is. Very, very quickly I turned the air quality in my bedroom from over 3,000 particles to less than 300. Air filters with a 13 MERV rating, cheese cloth over air vent, a room purifier. I would never have believed it if I had not seen it with my own eyes....
