Blueair replacement filter specifically designed for the HealthProtect 7300 series of air purifiers. This SmartFilter utilizes advanced HEPASilent Ultra technology, which combines electrostatic and mechanical filtration to capture 99.97 percent of airborne particles as small as 0.1 micrometers. The filter effectively removes allergens, dust, pollen, mold spores, pet dander, viruses, bacteria, volatile organic compounds, and household odors. Integrated coconut-based activated carbon provides superior adsorption of chemicals and gases. The RFID-equipped SmartFilter automatically monitors the filter status and communicates with compatible Blueair devices to indicate when it needs to be replaced, typically every 6 to 12 months depending on usage conditions. The book-like design allows for easy removal while containing trapped pollutants to prevent them from re-entering the air. Natural antibacterial polypropylene fibers inhibit the growth of bacteria and mold in the filter material. Compatible with Blueair HealthProtect models 7340i and 7370i. The filter maintains optimal airflow resistance while providing clean air with reduced noise levels compared to traditional HEPA filter systems. It offers efficient compatibility with pre-filtration through washable pre-filters to extend the life of the main filter. This replacement part ensures the continuous performance of your air purification system with precise filtration capabilities and intelligent monitoring functionality.
