Asked by rhonda April 18, 2021

Answers

The air intake of the Blue PURE 311 is all around the body of the air purifier- the portion covered by the cloth pre-filter. The air outtake is on the top of the air purifier where you can see the dotted spaces and feel the airflow.

Country of origin?

Thank you for your interest. This unit comes with a washable cloth prefilter and a particle plus carbon filter that is not washable and we recommend replacing every 6 months.

Are there other compatable filters

Almost Perfect
I bought this to clean the air and dust particles in the air in my barn house. I can tell a difference because I’m not sneezing, blowing my nose or taking Zertec as often! The only complaint I have is that it draws dirt to the outside as well as the inside and that makes it look less efficient.

Incredible Air Purifier
I bought 2 of the Blueair 311 Auto Air Purifier for my office and bedroom. My wife has allergies and this purifier has been incredible in helping her stop sneezing in the morning. I cannot recommend it enough. Super quiet also.

The device is lightweight quiet and appears to be working...
The device is lightweight quiet and appears to be working well. Burning food on the stove that creates a small amount of smell in the air triggers high speed filtration.I don’t know yet how it will work on smoke during the wildfire season but I already plan to buy a second one for the back of my house

Great features and convenient to use!
I bought this a month ago and I am glad that I did. Every time I burn an incense, the filter even in other room turns red so it seems very sensitive to dust, smoke etc. It probably also filters pollen as described (that I am allergic to), however if the windows are open and allergens are high, the filter does not turn yellow or red so not sure if it is very sensitive to pollen unless the air outside has smoke or has low air quality. The air feels fresh and clean though so definitely worth a buy!

Worked great while it worked
I bought in October 2020. Worked great as of last filter change (June 2021) I change every 2 months because we smoke. Now fan isn’t running.

The air feels so much better.
I was introduced to Blueair during a visit to Denver. The Airbnb I stayed in had a Blueair purifier and I thought it did a great job keeping the air clean. When I got home I bought one for my room and absolutely love it. My head feels way more clear than before I owned the purifier. I plan on buying another one for my living room.

Worked so well I got a second one
I bought this Blueair purifier because a family member with severe animal allergies was coming to visit for 2 weeks and we have 7 cats & dogs. We also live in the desert and have considerable dust that sneaks into the house. I am happy to report that dander allergies were kept to a minimum and the dust on countertops and other surfaces was dramatically reduced. I ordered a second one a few days after receiving the first. these purifiers have made an incredible difference in our indoor air quality!

Black Wall Effect
Haven’t had the smell issue people talk about. After a few months of use I started to notice the area around the purifier turning black (white walls, molding and window treatments). Now after a few months my entire room - walls, doors and window frames - are caked in soot. Going to need to get a deep cleaning. Not sure I want to continue using it if this is the downside.

Wow! Allergies, cats, and MMJ
So, my wife and I have really bad allergies, and 3 cats, and MMJ patient. I can't believe how wonderfully this thing works. I kicked it on right out of the box. And yes. I did check for the tiktok plastic bag thing, it's not there. No need to check! I ran it on auto for the first 2 hrs and got a blue light and it's very quiet. We wouldn't known it was working right til I needed to smoke. The light turned red and not 1 mins into smoking the 311 went red turned on full blast and poof its clean air.

A Quiet and Efficient Air Purifier
After looking a number of purifiers, I eventually relied on Consumer Reports for guidance and settled on the PURE 311 Auto. We have the 311 in our master bedroom. The unit is quiet at low and although a bit loud on high, we run it in auto and it has never run the speed up. We have experienced a significant improvement in breathing and nasal stuffiness since placing the 311 in our room. It just keeps the air clean!
