Functions as advertised

Bought a month ago. Nice blower. Wish controls were on topside of unit. Auto ppm detection and run cycle is nice, but manual says run continuously, off auto, for best results, so recommend to other buyers to buy versions without auto run b/c they are cheaper. Definitely good piece of mind for clean air.

Saved me from Cat allergies!

I am newlywed and my spouse brought two cats with her when she moved in. Having severe cat allergies i was desperate to find a solution. I researched various manufacturers of air purifiers including consumer reports which rated the 650 tops. After additional research i decided the pull the trigger on two units for my 950 sq ft basement. So far so good! I also love the wifi control from phone feature. These units have saved me and my wife the heartache of having to find a new home for the cats.

Better Than I Imagined

I purchased the Classic 605 about a month ago and it's better than I imagined. I used to snore every night. Now, I rarely snore and I sleep great. My wife says that she's sleeping better than she has in years. It has changed our lives. Thanks!

Love the purifier. Hate the App!

We love the air purifier. As other reviews mention it is loud on full blast. But we leave it low/medium throughout the day. My only complaint is that we cannot get it connected to our internet. The instructions do not work. I've tried multiple times and I'm typically tech savvy. It is also located in the same room as our router so there's no reason for this to be an issue. Plus we have 400!

Not bad - louder than expected

I was excited because blue air was known for quiet fans…this is not so quiet. At the lowest setting there is an intermittent buzz or whine…fan bearing noise. The middle setting buzzing goes away but obviously is louder since it moved faster. Highest setting is too loud to use for any extended period of time.

Works fine but….

This fan works but you must buy a separate gadget to get air quality read outs and that gadget is no longer available. I did not realize that until after I received the 605. Get the upgrade. I purchased a newer version as well (hat connects to the app), and it's much better.

The highest setting is way too loud

This model seems to do a good job cleaning the air but the highest setting is extremely loud and the lower settings don't seem to pull in as much air.

Not worth the money…

My Classic 605 is definitely not worth the money. For as big as it is, it doesn't work very well. It's extremely loud and I'm not happy at all. This is my second BlueAir purchase but I will not be back for a third. With so many competitors out there, go elsewhere!

I cannot get this thing to connect with the app, so I feel like since most functions are through the app, I am missing out on a lot. Really feels like a dumb move making this purchase.

605 classic doesn't live up to its good CR rating

Returned my classic. Why would you ever put a light, that can't be dimmed, on a unit someone might use in bedroom. Also, it is super loud and high pitched on its high setting.
