Wirecutter Pick
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."

Three-part filtration
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.

Features
One-button design
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.
