3 units bought, 3 units dead within days

Gender:Male
Verified Purchase:Yes
I purchased 3 of these and they all bricked themselves. No LEDs light, the fan won't run, just totally unresponsive. One ran a bit longer than the others but it has given up the ghost as well. What a shame... I've got 6 other Classic Blue air units that have been rock solid for years. What has happened to this company?
No, I would not recommend this to a friend.

Stopped Working After 2 Days

I bought the Blueair 511i max. It worked well for 2 days. After that, I could no longer power on the unit. I tried all of the steps that Blueair recommends on their website if the unit cannot be powered on. None of these steps worked. I returned the unit and bought another purifier from a different manufacturer.
No, I would not recommend this to a friend.

Works on cooking smells,but not poop.
on January 1, 2025

Gender:Male
Verified Purchase:Yes
Bought specifically to keep in a bathroom area that stays stinky. We have it set to “auto” so most of the time the indicator light is blue and the fan is running at a low speed. It picks up cooking odors from several rooms away and the fan immediately ramps up to compensate. Doesn’t seem to detect pooping odors right next to it though, as the fan does not ramp up, and the light stays blue.
I would recommend this to a friend!

Gas Stove Cooking

I love this air purifier. I cook with a gas stove and feel really good about how it cleans the air in our home so quickly. Even with running the fan on the stove, the indicator light on the air purifier turns red, and it will until the air is in our home is pure blue once more!

Great for airborne allergens!

Verified Purchase:Yes
When shopping for an air purifier for my son, who has terrible allergies, this model was recommended in Consumer Reports. It has been great! I did not buy the additional “allergen” filter, figuring I would try the standard filter first. From the first night, he was much less congested and able to sleep better. I think it is very quiet, especially on night mode.
I would recommend this to a friend!
