Less dust. Less cleaning.

Pulls airborne dust toward the purifier and captures it before it has a chance to settle on your floors and furniture.

Pet mess, meet your match

Captures pet hair and dander while activated carbon helps tackle unwanted odors, so your home feels fresher.

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.

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 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!

Clean the wick filter every 2–4 weeks. Soak the wick in a descaling solution using 1 descaling packet per tank of water for 2 hours, then rinse thoroughly with clean water.

Be sure to replace the wick filter every 6 months for optimal performance.

Bi-Weekly Cleaning Guide + -

To keep your DreamWell Humidifier performing at its best, Blueair recommends cleaning it at least once a week, or twice a week with regular use. Always disconnect the device from power before cleaning.

Water Tank

Clean the water tank with a mild detergent, or place it in the dishwasher.
Dry the water tank thoroughly before reassembling the humidifier.

Wick Filter

Soak the wick filter in a citric acid solution (20 g of citric acid per 1 L of water) for 1 hour. If needed, you can soak it for up to 2 hours.
Rinse the wick thoroughly under running tap water before reinstalling it.
If you have the DreamWell mesh fabric replacement wick, it can be machine washed on a gentle cycle.
