Clean your air of particles—including viruses, bacteria, and fungi—with the Fellowes AeraMax Pro air purifier collection. Boasting a four-stage filtration system, this series uses a True HEPA filter. The collection includes three models: AM2, AM3, and AM4. Each choice can remove up to 99.97% of contaminated airborne particles as small as 0.3 microns! Designed for commercial use, this air purifier collection improves your indoor air quality. The AeraMax Pro series continuously monitors how many people are in a space. Additionally, it tracks real-time air quality with its multiple sensors. Thanks to their environmental monitoring, the air purifiers can automatically adjust their fan speeds. Finally, mount them on movable office walls from Trendway or install them on traditional drywall. There is also a floor stand model that you can use anywhere in your workspace.
