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.

    Blue Pure 311 Auto Series Particle + Carbon Filter

    Love this Carbon Filter System. We use it in our 42 ft fifth wheel while traveling to areas with fine sand and dust. It is also effective when cooking and you can hear it go to work though it’s still quiet. Love it would recommend to anyone !

    Excellent product. Quiet and easy to use. The filter replacement is simple, and ordering is eliminated by the subscription approach.

    Quiet air purifier with easy filters

    The Blue Pure 311 air purifier is very quiet and removes a lot from the air. There is even a night-time setting where it still cleans, but at a lower level where we don't hear it at all. The replacable filter is easy to installl.

    Makes a real difference!

    We originally got this when wildfires were raging near us, and needed to have one room with clean air. Since then, it has been doing yeoman service through pollen, pet dander, blowing dust, and more!

    Love these

    Been using Blue air for years. The unit turns up when there's stuff in the air, pulls smells of cooking and SO much dust out of my space, and they never give me any trouble. The filters are clearly high quality and so the job much better than alternatives I've tried.

    My filter never turns red to indicate the need to change the filter. What’s wrong? Does it take a long time?

    doesn't fit "Blue Pure 311 Auto"

    The filter is much too large for my "Blue Pure 311 Auto". Too wide and too tall? Why? Has something changed? Filter much too large even though description says it should fit a "Blue Pure 311 Auto"

    Filter recharge

    Blue Air Filters come right on time. The filter I replace is filthy and the new filter looks so pristine at the moment. The Blue Air machine though, will be doing its job and cleaning the air in my living room and in 6 months will look like the old filter this month. This is a great air cleaner and I love that I don’t have to remember to send for a new filter. Thanks Blue Air.

    Great Ait Purifier

    We have been using our Blue Pure 311 purifier since Covid came around in 2020. It is so quiet, we don’t even notice it. And it does a great job. One of the best purchases we have made for our health.

    It works!

    I've been consistently changing my Blue Air filters since I purchased two Blueair cleaners quite a few years ago. I chose to change it every 9 months. Every time the removed filter is a dirty grey, so I know it's working well! I keep my windows slightly open for a flow of fresh air to circulate throughout my space, so the filters have quite a challenge to keep up with keeping my air fresh and clean.

    (no review title)

    Be careful buying this product. I have a blueair and it works beautifully, however the filter needs replacing and I can't find it anywhere. Seems like this company pushes you to buy a new machine....

    Watch out for the filter reorder size!

    I also fell for the 311 vs 311 Auto difference in filter size and ordered the wrong replacement filter (note 311 is shorter than the 311 auto. It would be helpful to make the difference between these two more obvious!
    1 reply from Blueair team - 6 months ago
