Key Features

• High filtration efficiency: The HEPA layer captures at least 99.97% of tiny airborne particles down to 0.1 microns, helping reduce smoke, dust, and pet dander in living spaces.
• Activated carbon layer: A built-in activated carbon filter reduces light household odors from cooking, pets, and incidental smoke, improving perceived air quality.
• Easy maintenance: Filters are designed for tool-free installation and, based on typical usage, are intended to be replaced every six months to maintain peak performance.
• Responsible materials: The filter media includes FSC-Certified paper, indicating responsible sourcing for the paper components.

Who It's For

It is also a practical choice for households with pets or light cooking odors that benefit from combined HEPA and activated carbon filtration.

It is not for people who use other Blueair models such as 211+, 411i max, 511, 311, or 311i+ MAX121; the manufacturer emphasizes the filter is only compatible with the listed models, so buyers should confirm the model number before ordering.
