Blue Pure 411+
Add to cart options
Filters the air at the industry-recommended rate of 5x an hour (or about every 12 minutes) in a 185 ft² room to effectively lower particle levels and maintain a comfortable environment in your nursery, small bedroom or home office.
Building on the functional design and efficiency of the standard 411, the Blue Pure 411+ features a slightly larger room size capacity at 185 ft² and premium design upgrades like a sleek-mesh frame, anti-scratch matte coating, and clever magnetic cord straightener.
A fabric pre-filter offers the first layer of protection, catching large particles 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.
Identified as one of the quietest products in the category and awarded the Quiet Mark by the Noise Abatement Society (NAS).
Verifide by the Association of Home Appliance Manufacturers (AHAM) for performance and Clean Air Delivery Rate (CADR).
Rated as an energy-efficient air purifier by the EPA's ENERGY STAR rating program.
Certified for ozone emissions and electrical safety by the California EPA's Air Resources Board (CARB).
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.
Change color in seconds
Match to your space with six fabric pre-filter colors (Dark Shadow included). Or, for a Scandinavian look, go without a pre-filter to show off the sleek white-mesh frame.
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.

After about 7 seconds, the LED light will automatically dim to 10% brightness.

The Blue Pure 411+ builds on the functional design and performance efficiency of the original Blue Pure 411 model with an increased Clean Air Delivery Rate (CADR) and room size capacity (185 ft²), at relatively the same compact size as the original.
Press and hold down the LED button for 10 seconds to reset the replacement filter indicator.
To extend the Limited Warranty from one year to two (2) years, simply complete the product registration form in the 'My Units' section of your customer account, within (60) days of purchase or register through the Blueair mobile app.
Vacuum the exterior of the fabric pre-filter to remove dust as often as you'd like. When the pre-filter requires a deeper clean, it can be wasehd on a gentle, low temperature cycle in the washing machine.
The LED indicator will turn yellow after 5 months of operation to warn that it's almost time to change the filter. When the indicator light turns red (one month later), it’s time to change the main filter.
