The 212+ auto filter
My 211 cleaner has started making a crackling noise when it runs this is quite noisy and I can’t run it with this problem.

Filters air in living room and kitchen
Sits directly between our kitchen and living room and filters both. We keep it on the middle setting and you would never know we have 2 furry Pomeranians. If the red indicator appears (usually after a bold cooking) we turn it up to high and it usually on takes a couple minutes to turn blue again. Filter lasts about 9 months.

filter replacement
It arrived within a few days, and my son was able to install it without any problems.I'm not sure if the unit is coming on automatically as it did in the past. Severa times I have had some strong cooking dors that in the past would have triggered it to switch on, and it didn't seem to do so. Having read the direction numerous times, I am hoping I have it set correctly and it will react when the air needs to be cleared. Love the Blue Air Cleaner

Blue Air Auto Particle Filter
I replaced the Blue Air Auto Particle filter and noticed when I removed the old one lots of debris and particulate matter in that old filter - which makes me think that the filter is doing its job of removing the bad things in my air. I feel using this filter that the air circulation in my living room is much better - kudos to Blue Air.

Great device!
The device keeps the circulating air clean and much better than it otherwise would be.

I’m generally happy BUT
When I first started using the filter, it gave off an unpleasant chemical-type (I guess) smell. Better now but it startled me. Hasn’t done that before ever.

It's great!
This is an effective, very quiet air filter. Even when I forget to start it keeps the air effortlessly clean. Getting the filters on auto-ship is super convenient.

life changing
I noticed a positive improvement in my seasonal allergies within a couple of months of using this filter - a very worthwhile subscription buy, in my opinion

Does the job
Living in a semi arid climate dust is a constant battle. This product does a great job keeping down dust and removing odors.

Not working well.
Despite replacement of filter and washing pre-filter allergy symptoms persist, and air does not seem as fresh as it had with my old Honeywell HEPA air purifier.

Excellent!
This is really helpful in managing pollen and dust-related allergies!
