Description
Genuine Blueair Replacement filter compatible with Blue Pure 311 Auto air purifier. The Combination Particle + Carbon filter protects against both gaseous and particulate contaminates. Advanced polypropylene filter media removes particle pollutants from your indoor air, such as pollen, dust, and pet dander. At the same time, a layer of activated carbon mesh traps light household odors from pets, cooking, smoke, and more. The 360-degree design allows the filter surface area to be over 13 square feet in size. Unlike look-a-likes, authentic Blueair replacement filters are designed to maintain premium performance over time and ensures your warranty remains intact. For optimal performance, replace the filter about once every six months when used 24 hours a day. The twist-and-change filter is easily removed and replaced and is recyclable at the end of its service life. Please check your local recycling facilities for availability.

Good machine
I have 2, they work very well with a fresh filter. You can smell the difference in the air. I have read a few reviews about not being able to find the correct filter? How? Just search the model name and number and the correct filter pops up. People must not know how the search function works.

Great for allergy symptoms
I have allergies all year and since I started using the Blue Pure air filter I have noticed a huge difference. My sneezing “attacks” have almost completely stopped and I definitely don’t have the allergy symptoms as bad anymore. When I open my windows and shut my Blue Pure off, my allergy symptoms come back.

Grateful for this!
We have 5 air filters in our house. We had ours running before, during, and 3 days after the recent fires in Los Angeles (until the power was cut). We got power back a few weeks later and turned them on again. We are still in an evacuation zone. Our house is still standing but had almost no smoke. Thank you BlueAir!

Great Little Air Cleaner
The only reason I didn't give 5 stars is that the filters are a little expensive. Right now I'm waiting on a filter for my living room machine. I can tell it's not on because when I come home from work, my house smells musty and kitchen odors last forever almost.

Efficient At Removing Pollutants
Filter swap is fairly straight forward. Removing the old filter and comparing it to the new reveals the dirt/pollutants the filter removes from your environment. Pretty eye opening to say the least.

Still don't know if air purifiers are helpful
I keep replacing my filters but I still don't know if Blueair or any air purifiers are beneficial to me. I still have bad allergies and my bedroom (where I operate the Pure 311) still traps cooking odors because it's the only room in my house where I never open the window. When I'm doing some soldering the 311 seems to suck in some of the nasty fumes so that's the only time I know it's working. And the red light turns on too. The newest filter replacement I received has a smell that fills my room, so one star removed.

Thumbs down graphic, would not recommend
12 April, 2023Verified purchase
311 was great, except you can't get the right filters now
This does NOT fit regular Blueair 311 machines. It's so annoying that Blueair creates multiple sizes in the same line... I purposely bought a Blueair machine because I wanted to be able to buy filters I needed. Now they don't sell the "regular" 311 filters ar Target. Beware buying this trendy brand- you can't get the right products to keep using the filters.

Great little filter
Great quiet air filter for our family room! Since it's so quiet I keep in on 24/7 on very low speed. Catches lots of dust and pollution. The room smells clean and happy.

Blueair products are very good. We've used the 311 model for months. I would recommend it.

My Aussie Ate My Product
I'm sad to say I can't actually review the product itself, because before I could install them, my demon Aussie shepherd dog, Bingo, woke up earlier than I did one morning, and tore them all to shreds! But I am about to order more and I will say, they came quickly! So 5 stars for speedy shipment! Hooray!
