Customer Ratings & Reviews

Works great bought 3 have had no issues so far with any of them.

Night mode works great and the turbo mode definitely moves air.

A little loud but overall really simple to use. Turning off and on and switching the settings it’ is a bit tricky.

Works well in a smaller sized room. Auto feature works well.

Wasnt that good it turned on and off by itself but it didnt do anything in the room i put it in. Returned it

so far so food. Using it for my living room space.

The 411 Auto purifier seems to work good enough for its price. However, after owning it for only 2 months, mine has just started making some kind of clicking rattling sounds from the fan at all speeds. The noise is becoming very annoying. If I turn it completely off and let the fan stop, then turn it on again, I might get lucky where it spins without any clicking. But it eventually returns. I can only assume the parts are poor quality. Will have to look into other brands.

it helps keep my room feeling fresh and clean not to mention the soft noise it makes helps me get sleepy

Very quiet. I feel healthier just knowing I have it.

Great purchase! Works great!!! Use in bedroom 12x12

Works perfectly,gets the job done, totally recommend

Great purchase. perfect for people with allergies.

We bought two… one works fine, the other shuts off and turns back on randomly. Looks like I will have to return one.

I still see the same amount of dust so I don’t think it works. There’s no difference.

Have not noticed any difference in the air eyes still puffy in the morning and don’t help with the dust

Yes, according to all the factory specs and government testing metrics, model 411 Auto air purifier excels in filtering ultra tiny particles (down to .1 microns --it is not certified to filter particles as small as Coronavirus, nor does it claim this ability) thanks to it's HEPA filter. The filter is extremely accessible and easy to change. That aside, what I liked was how easy it is to operate thanks to a one button control, and it's AUTO setting, and how easy it was to move it about, because It weighs less than 8 lbs -- and has an easily transportable cylinder design. I have been using it in a guest bedroom of about 150 square feet (the rated capacity equals rooms up to 190 Square feet), and it is so silent in AUTO mode I have to give it a look (to see the small unobtrusive blue LED ) to make sure it is on. Finally, this air purifier has 3 layers of purification and contains activated carbon, hence , it deodorizes. It is also Energy Star rated so that it is inexpensive to run 24 by 7. I could not be more pleased with it's performance.

The Blueair - Blue Pure 411 Auto HEPASilent Air Purifier lives up to it’s name. It’s so silent I forget it’s even there. It is very lightweight and easy to move around. It’s not for large spaces, but would work well in a bedroom or office. My first impression was that it looked homemade and not very high tech. The manufacturer’s description of it as “simple” is accurate. The removable top part is a fan with an LED light that changes to red when the main filter needs to be changed and a button to control fan speed. There is an outer, machine-washable, cloth “pre-filter” that surrounds the main filter. The product comes with a gray cloth "pre-filter", but other colors can be purchased. The purpose of the outer cloth covering is to catch large particles and prevent them from clogging the HEPA filter. The manufacturer states that the unit removes smoke, dust, pollen and odors. I apparently don’t have those in my air since the LED air quality light consistently indicates that my air quality is good. Because of that I can’t say how efficiently it cleans polluted air or how accurate the sensor is. I haven’t tried washing the cloth cover. My concern is that it might shrink and if it does, the two pieces of velcro that hold it in place won’t meet. I believe that it will work as expected, even though the design is more basic than I had anticipated..

I looked at scientific literature, and it appears that the finding is that this filter is not as effective against covid at it seems to be. I plan to return it, because I used it while in a small room with people at my job and I did, in fact, get covid.

I can't really tell if this is making a difference, I think it is but I can't really tell. It's not like a huge difference in my room since it's been installed amonth ago. But I really dont' know. Maybe it's working, maybe it's not.

I really like this air purifier. I like the looks of it. It sits in a room like a piece of furniture. It doesn't take up too much space and looks quite nice. It is quiet when the air is clean, I have it at the foot of my bed. I'm a light sleeper that wakes to most sounds. This has not awakened me yet. I forget that it's there. When I first set it up I would put my hand over it to check that it was running, now I just check the light sometimes to make certain. When it detects the air needs more cleaning the speed automatically adjusts and the color of the light changes. Even with the fan running faster it's still pretty quiet. Set it and forget it until the filters need cleaning or you can adjust the speed if you feel it's necessary to your conditions.
