The Blueair Joy S filters the air at the industry-recommended rate of 4.8x an hour (or about every 12.5 minutes) in a 17 m� room to effectively lower particle levels and maintain a comfortable environment in your nursery, small bedroom or home office.

Upgraded features
Building on the functional design and efficiency of the standard 411, the Joy S features a slightly larger room size capacity at 17 m� and premium design upgrades like a sleek-mesh frame, anti-scratch matte coating, and clever magnetic cord straightener.

Three-part filtration

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.

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.
