Description
xThe BLUEAIR Blue Pure 311 Replacement Filter is a genuine part built for the Blue Pure 311 Air Purifier (non-auto). It blends a particle filtration stage with an activated carbon mesh to tackle both airborne particulates and odors. This isn't a generic add-on; it's designed to work in harmony with the purifier to help maintain a fresh indoor feel.
Engineering for steady airflow and long-lasting performance
With a 360-degree air intake and up to four times the filter surface area versus models relying on only basic filtration, this filter supports consistent airflow and efficient filtration over time. The result can feel steadier and less noisy as the purifier operates.
Key filtration layers combine particle capture with odor control, so you may notice crisper air in rooms where cooking smells, tobacco smoke, or pets leave a trace.
- Filters particles down to 0.1 micron, including pollen, dust, and pet dander.
- Activated carbon mesh targets odors, VOCs, and common indoor smells.
- Designed for up to six months of use under typical conditions.
- Genuine Blueair parts optimize air flow and overall purifier performance.
Compatibility and care
