Blueair Blue Pure 211+ Auto Replacement Filter – Particle & Activated Carbon

Genuine Blueair replacement filter for Blue Pure 211+ Auto

Designed to work with Blue Pure 211+ Auto air purifiers, this replacement filter blends particle filtration with an activated carbon mesh to address both solid pollutants and odors. The result is a refreshed, breathable indoor environment you can notice as you move through rooms.

How it works

• The particle filter captures particles down to 0.1 micron, including pollen, dust, pet dander, and more, helping you breathe easier during allergy or dust seasons.
• The activated carbon mesh traps light odors and gaseous pollutants such as VOCs and tobacco smoke, contributing to a fresher scent and feel in living spaces.
• A 360-degree air intake and a larger filter surface area (roughly four times that of some replacement filters) support efficient filtration and may help maintain steady airflow over time.
• Independent testing confirms zero ozone generation; the filter works with Blueair's electrostatic plus mechanical filtration system to maximize safety and performance.

Usage, maintenance, and savings

• Replace about every 6 months, with longer or shorter intervals depending on usage, air quality, and household activity.
• Consider subscribing for auto-delivered replacements and save up to 10% on your orders.
• Genuine Blueair replacement parts are designed to preserve airflow and filtration efficiency, helping you get the most from your purifier.

Real-life scenarios

If you have pets, occasionally smoking or cooking in the kitchen, or seasonal pollen, this filter can help reduce the presence of airborne particles and odors in living areas, bedrooms, and workspaces without changing the purifier’s look.

Compatibility and care

• Only compatible with Blue Pure 211+ Auto (not for the non-auto 211+ unit).
• Replacing on schedule helps maintain peak performance and reduces the chance of decreased airflow due to clogged media.
