Running great!
I bought the 200 and the 503 air purifying system when I moved from my home to a smaller space where I knew they would be perfect. This was 11 years ago and are still running like new with absolutely no noise. I am amazed how quiet and well they work. I never write reviews but I really do love these Blueair filter systems and so glad I still can still depend on them in my home space. I am very careful whenever I move them to not drop or jar them. I buy my filters from Blueair on the subscription plan. I'm so glad I have these filters in my home. My home space air feels so good.

Poor WiFi connection and glitchy App
I’ve had this for a couple years but I noticed within the first year that the WiFi would just lose connection. My disappointment is with the wifi connection and the fact that the unit does not automatically reset when new filters are installed. I’ve done all the steps to try and connect it, but I just manually turn it off and on each evening. Also, there’s a high pitch whirring that started up even though I’ve kept it clean and swapped filters in a timely manner.

Classic 600 experience
When I replace the filters it’s obvious they are removing particulates from the air. My disappointment is with the wifi connection and the fact that the unit does not automatically reset when new filters are installed.

work great but chemical smell
2 1/2 stars - they have a chemical smell i don't like and i wonder if the chemicals can possibly be good for me, if they smell so bad. so i only run my air purifier when the air quality is particularly bad, especially smoky. they're very effective for the smoke! but i run them so rarely, i leave them unplugged most of the time. since i don't run them constantly (one on each floor) i'm in a quandary about the every 6 month subscription - as the boxes are stacking up.
