Air purification made for pet parents

  • Dual air intake & vortex airflow

    A dual air intake & vortex airflow pattern keeps airborne dust particles moving into the air purifier. Once inside, dust particles stick to the charged stainless steel pre-filters, like a magnet.

  • Captures dander & unpleasant odors

    The pre-filter captures large particles like pet hair. Then, the particle filter traps allergens², while the activated carbon neutralizes smells, keeping your home fresh and clean for you and your furry friends.

  • Pet-Proof User Interface

    Strategically hidden user interface built to withstand the curious paws of your extra mischievous pets.

  • Sleek Scandinavian Design

    Minimalist Scandinavian design to effortlessly enhance and blend your home.

”I am definitely seeing less dust on my furniture. Also, when I look at the filters in the air purifier there's actually dust and hair from my Yorkie”

    Auto Mode works great!

    This is my third purifier from Blue Air and I love the design! We don’t have a fan in our kitchen and this unit really revs up when it’s on auto mode and I’m frying food. I hate to think how bad our air was when I was cooking before!

    Great product

    It is very quiet and we have many pets. Our cats seem to avoid scratching at it too! Nice and light to move around too!

    Great job with dust

    Very pleased with my dust magnet. Makes the air feel cooler and cleaner and I love the Bluetooth accessibility. Overall, it's a lovely piece of furniture as well. I have two of them!

    A Dust-Busting Believer Was Born in Our House

    We had a serious dust problem, the kind where you wipe a surface down and it's back within a day. We'd tried everything short of living in a cleanroom. Then we brought home the Blueair DustMagnet 5440i, and honestly, it felt a little like cheating.

    Within the first week, the difference was striking. Surfaces that used to collect a visible film of dust stayed clean noticeably longer. The unit just quietly does its thing, the auto mode picks up on air quality and adjusts the fan speed on its own, so most of the time we barely notice it's running. And when it is running on higher speeds, it's surprisingly unobtrusive given how hard it's working.

    My wife was skeptical at first - understandably so, because we'd spent money on "solutions" before that didn't deliver. She's now a full convert. In fact, she's the one who checks the app more than I do.

    Speaking of the app, it's a nice bonus. Scheduling, air quality monitoring, filter life tracking, it all works without fuss, and the Alexa integration means we can adjust it without even picking up a phone.

    Does it look good too? Yes, it’s the rare appliance that actually improves the look of a room rather than cluttering it.

    If you're on the fence, the DustMagnet 5440i does exactly what it promises, and our home is genuinely cleaner because of it.

    I just had to buy a third

    We’ve had two for years and have now added a third. They greatly reduce the amount of dust we have in the house and are easy to maintain.
