Customer Ratings & Reviews

Its pollen season and i have a cat that sheds a lot - as soon as i bought one of these for my living room, my sneezing stopped and i feel like a new person. Can control with your ohone via bluetooth and is not as loud as other purifiers!!!

Does a good job. I like the fact that I can operate it with an app.

I would have reviewed this without an offer to enter a contest. This air purifier has been the best purchase I have made. Between the app to control and the ability to identify what is causing high impurities to make changes in my environment I am quite satisfied.

Bought as a gift to my uncle. I am not sure if they used it.

Love this air purifier. The city flushed the dear line in front of our house. Odorscame up through our line and we had problems getting rid of the order until we turned this on.

Keeps apartment clean, just moved into apartment and it wasn’t the cleanest air

Okay this thing is awesome. My office always smells like pet dander so i thought I’d give this a try. Left it running for just 1 day and its already SO much better! So happy with this purchase.

We have all the sizes and needed this one for our bedroom.

This product has a very interesting design as the filter is part of the structure of the device and it is quite solid. The device also includes a washable fabric prefilter. This fabric functions both as a filter and as a nice decorative cover over the carbon/particle big filter. Overall, an ingenious design including the structure and the touch controls. There is also an excellent app for the Blueair filters. I have another larger Blueair, so I was able to just add this filter to the same app. Controls are so intuitive you may not need to even look at the user manual which is also well done. The manual does show the parts of the system including a ‘noise/shield ring’ to reduce fan noise. There is a sleep mode which can reduce the fan speed such that there is no perceptible noise. The only way to tell the fan is even moving is to place your hand above the unit to feel the breeze from the unit as it filters your air so quietly. You also have manual controls on top of the unit which are touch controls - very nice, and they work great. One caution is to avoid touching the on/off button-area while changing fan speeds. You'll do this once I think and accidently turn the unit off. It is one small area that the engineers should look at, I'd suggest a double touch to turn the unit off would be a slight improvement. I recommend using the devices WiFi capability and installing the Blueair app. Open the app and it will show you available devices, pick the picture matching your unit and the rest of the steps are guided by the app. You do need to have Bluetooth on as well. Sometime products require several times to get connected, but this unit did it in one step and quickly - tip of the cap to the programmers and engineers at Blueair. Unlike cheaply made units, this one has the quiet fan speed which is very important if used in a bedroom. The entire unit is made of quality materials and the engineering is superb. I would highly recommend this unit for a bedroom or small living room.

I got this just on time for sprin pollen season. Keeps my apartment dust-free and my breathing hasn't been better. Worth the money for sure!

I have been waiting a few months in order to review this. So far I am very happy. it picks up any smells all they way from my kitchen.

Great equipment and easy to manage. My family has some allergies and the Blue Pure 311i helped reduced the allergies.

We love our Blueair! We returned our Dyson purifier that costed 4x as much and does not compare to the quality of Blueair! We will be buying more!

I have two of these units. What I like most is the "auto" feature....this unit ramps up when conditions in the air call for additional filtration.

Works great this is very easy to operate—- has an app you download to your phone—- simple to do

This does the job great. Filters the air in an auto body shop office. Makes a big difference.

It seems to have problems where the timeline doesn't remember what the past air clarity and always sets it to it's current air clarity

Best decision i made was to purchase this air purifier!

Great air filter we actually have a couple now and love them

I can only run this for short spells because the plug gets very hot & I'm afraid of fire. I only plug it in to wall outlets as instructed but it still gets much too hot.
