xOverview
Enhance your BLUEAIR purifier with the Classic 400 Series Genuine Particle Replacement Filter. This filter is designed to trap particles of multiple sizes while maintaining strong airflow, helping your space feel clear and comfortable without sacrificing performance.
Key design features include a gradient filter structure that resists clogging and prevents re-release of trapped particles, plus ultrasonically bonded media that keeps fibers from escaping into your environment. The result is a steady flow of clean air as you operate your purifier, even when the filter is heavily loaded.
The advanced polypropylene media captures particle pollutants down to 0.1 micron, including pollen, dust, and pet dander, supporting a more refreshing indoor atmosphere.
