I guess it’s good.
I bought this unit for my parents home that never gets much cleaning unless I do it. They also have a dog that sheds. When I set it up, it said the air quality is excellent. So I’m kinda wondering if it’s doing any good. I will keep it but wish it was smaller.

Cleaner Air!
We were surprised who dirty our filter was! We love the alert to change the filter and the easy to replace.

Great Product!
I bought a 211 MAX and just replaced the filter after about 9 months use! The product has been Great! However, the company's insistence on having adds appear on my computer screen at every turn is ANNOUYING! I can only use one unit of 211 Max in my home at this point!

Persistent odd burning smell
I’ve had blueairs in every room of my home for the past 6 years. This is the first purchase where, while very happy with how quiet the machine is, I’m disappointed in the product. The smell coming from the machine has been persistently a bit like a burning mixed with a vaguely chemical smell. Also, the light does not fully dim on the night setting, which is truly annoying,

Filter Review
It was easy to change the filter. I have very bad allergies. I think it helps some but I am outside a lot in the daytime so hard to tell.

My grandson ordered when he was talking with you for me. I didn’t need a filter now but will have when I do. I hate I didn’t get my discount. He didn’t realize to ask for it. We love air purifier.

Great Air Filter
Easy to change the filter and reset the unit for the new filter. Sometimes when cooking the smoke generated has triggered the unit across the house. Does a great job circulating the air quickly.

Great filter but ...
... I lost WiFi connection in the process and couldn’t reestablish it. Troubleshooting steps did not resolve.

I still wake up with my ears ringing
I have a problem with marijuana smoke from my upstairs neighbors. The filters help a lot, but I'm still suffering some effects from it. I still wake up with ringing in my ears. That is IN PART, due to the marijuana smoke.

Works great, better than expected
I've purchased three of the Blue Pure 211i Max Particle + Carbon Filter air purifiers for three homes and they work better than expected. At the cabin where I have a wood burning stove, the air purifier increases strength immediately when it detects smoke in the air. At home, I have less dust, I'm sneezing less, and when we had salmon the other day there was hardly any odor in the air.

New filter
So glad I got a new filter. I had no idea how dirty the last one was until I replaced it. It did last a couple of years but our air quality it usually pretty good.

Excellent Filter
I just replaced the filter in my unit with this same filter. After 9 months, I could not believe how dark the filter was. We run our 211i Max 24/7 due to allergies and pets on top of regular vacuuming with a unit that has a sealed HEPA system. I was amazed at what this filter traps. We’ve noticed a significant reduction in allergy symptoms since we started using our Blueair with this filter, so I highly recommend it!
