BLUEAIR Blue Pure 211+ Auto Genuine Replacement Filter, Particle and Activated Carbon, fits Blue Pure 211+ Auto Air Purifier

At the six months mark, I change my filter. When you take the old one out you can see just how much it is filtering out of the air you breathe! Well worth the investment.

Feel comfortable in knowing this unit is cleaning my air in our upcoming fall/winter germ season

Better than other air purifiers I bought before, 360 degree air intake and top air output, easy control, but you cant keep the top indicator light on.

After purchase, this product worked well on auto setting for a few weeks. Then, about 2:00-4:00 am EVERY MORNING, it would kick into high fan speed, which woke us up. Did maintenance according to book, with vacuuming inside, inspecting filter, cleaning sensor with Q-tip, etc. Still did it. Contacted company via their website, and received confirmation they received my message. 2 weeks later, I still have not heard back from them. The least they could do would take a few moments to respond! Save your money and get a quality product from a responsive company.

Appears damaged and not fully assembled.

I have allergies. I need this room air filter. I did not realize when I bought that I would need to replace the filter twice a year at about $75 each. This is a cost purchasers need to factor in evaluating room air filtration options. Otherwise the product works well in a moderate size room.

BlueAir 211 Purifier is the BEST. It does clean the air and requires very little but a place to plug it in. Follow the instructions and buy the one appropriate for your size room,

This genuine Blueair 211+ filter puts out a sickening chemical smell that will not go away after 48 hours like they say. Could not stand it after a week. Returned for replacement.

It’s a filter. As long as it fits, nothing to worry about. I don’t have a way to measure the effectiveness.

Failed right after I installed. Red and orange light ALL the time and shuts off. This whole unit is a complete rip off and failure
