The easiest air purifier
I love the simple on button, 3 speed fan on my 411 air purifier. I have had this since 2020 and it is still going strong thanks to the red light alert to remind me it is time to change the carbon filter.

High Quality Replacement Filter Subscription
I replace the filters in my two 411 room purifiers on a regular subscription. It helps to a have a spare set of outer prefilter covers to make changing effortless.

Works great
We got this during wild fire season a few years ago. We were so glad we did. After two years we realized how much other dirt was getting filtered out. We are pleased with this unit.

Toxic chemical smell
Blueair used to have good filters without toxic chemicals on them. And they have decided to now start putting some kind of bad smelling chemical on the filters. I have filed multiple complaints with the company. Yet it seems to be all of the filters now no matter which type it is. And I’m very angry because I have a bunch of these machines and can’t replace any of the filters.

Thank you for taking the time to leave a review. I’m sorry to hear about your experience regarding your new 411iMax Replacement Filter. It's possible that the filter may emit a temporary odor after being removed from the packaging, but it should dissipate after a few days.

Pure clean
It seems to doing its job and works well . After a while the motor gets louder and starts humming , sounds like it may be dying soon. But it does purify the air and I can tell a huge difference. I just wish it had low, medium, high adjustments. It only has low and high . I don’t want to keep turning it on so I just leave it on in my bedroom and the room smells fresh at night

Filter does not fit
Ordered filter for my Pure 411. It was too large and did not fit snugly. I have ordered these in the past with no issue. Waiting for a replacement. Hope it fits properly.

Decrease in quality
At some point BlueAir changed their filter and I’m not pleased with the change. They significantly decreased the quality and amount of materials used, specifically in the black piece of the filter. If you’re going to use cheaper material, the price should be cheaper.

Love Hate Relationship
I’ve had two of these for several years. They work well, clean the air after cooking, vacuuming, etc. and the filters are dirty when I change them indicating they really do work.However, they really need to rethink the power button and indicator lights. My change filter red lights never go off, even when the I’ve just changed the filter. Even more annoying is there’s no feedback on the power/fan button, you have no idea if pressing the button is doing anything. No different feeling or light. Eventually after pressing many times it shuts off. I no longer attempt to turn it off when I change the filter, I just unplug it so it hopefully stays on the same setting.

Best air filter
We’ve tried many brands over the years. The 311 and 411 do the best job at the best price. And Blueair makes the subscription process very easy to manage and adjust as needed.

My BlueAir Filters are the workhorse I need
I have had these units for a few years now, and they are so sturdy and dependable. The filters grab all kinds of dust and particulates and help my home stay healthy and clean. I highly recommend these filters!
