Operating Principles (Filtration System)
The Tailulu D09 replacement filter utilizes a 3-in-1 filtration system to ensure comprehensive air purification:
- Pre-filter: Captures larger particles such as lint, fibers, hair, and pet fur, extending the life of subsequent filters.
- H13 True HEPA Filter: Traps 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, pet dander, and mold spores.
- Activated Carbon Filter: Absorbs smoke, volatile organic compounds (VOCs), fumes, pet odors, and cooking smells.

Maintenance
Regular filter replacement is essential for optimal air purifier performance and air quality. The filter life depends on usage and air quality conditions.
- Replacement Frequency: It is recommended to replace the filter every 3-6 months.
- Filter Indicator: The air purifier's filter indicator light will illuminate when a replacement is due (typically after 1440 hours of use). Follow the 'Reset Filter Indicator' step in the Setup section after replacing the filter.
