Quiet Mark awarded
Sleep without disruption with one of the quietest air purifiers in the category as identified by the Quiet Mark. No louder than a whisper on low (17 dB) and up to 46 dB (a normal conversation) on high.
ENERGY STAR rated
ENERGY STAR rated to use less energy than the average LED lightbulb (about 10 W) - so you can keep it running all day and all night without having a second thought about your electricity bill.
Washable fabric pre-filter
Designed for small rooms
Filters the air at the industry-recommended rate of 5x an hour (or about every 12 minutes) in a 15 m² room to effectively lower particle levels and maintain a comfortable environment in your nursery, guest bedroom or home office.
Independently reviewed by the experts at Wirecutter, the Blue Pure 411 ranks as one of Wirecutter's top air purifier picks. Featured in Wirecutter's "The Best Air Purifier" article, they called the model "Small, effective, and attractive."
A fabric pre-filter offers the first layer of protection, catching large particles like pet hair and dust and extending the life of the primary filter. The combination Particle + Carbon Filter uses a layer of activated carbon to filter light household odors from pets, cooking, and smoking, while the main particle filter removes airborne particles, like pollen, dust, pet dander, and more.
The secret behind powerful filtration
Our unique combination of electrostatic and mechanical filtration that we call HEPASilent™ filtration technology sets us apart. The combination allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance— resulting in quieter and more energy efficient air purifiers.
Quiet Mark awarded
Sleep without disruption with one of the quietest air purifiers in the category as identified by the Quiet Mark. No louder than a whisper on low (17 dB) and equivalent to the noise level of a library on high (46 dB).
Simple to place
Unlike some air purifiers with strict rules for placement, the Blue Pure 411 uses a 360-degree air intake, meaning you can place it almost anywhere in the room without compromising performance.
Low energy consumption
ENERGY STAR rated to use less energy than the average LED lightbulb (about 10 W) - so you can keep it running all day without a second thought.
Extend filter life
The colorful fabric doubles as a pre-filter, catching large particles and extending the life of the primary filter - vacuum the fabric or toss it in the washing machine whenever it needs cleaning.
Forget about adjusting settings and knobs - a single button controls it all and lets you know when it's time to replace the filter.
Easy filter change
The built-in LED warning system glows red when it's time for a change. For optimal performance, we recommend replacing every 6 months.
Automatic LED dim
After about 7 seconds, the LED light will automatically dim to 10% brightness.
