4. Operating Principles (Filter Function)
The JORAIR D09 Replacement Filter utilizes a multi-stage filtration process to purify the air:

- Ultra-fine Pre-Filter: This initial layer captures larger airborne particles such as dust, lint, fibers, and pet fur, extending the lifespan of the subsequent filters.
- HEPA Filter: The High-Efficiency Particulate Air (HEPA) layer is designed to capture up to 99.97% of airborne particles as small as 0.3 microns. This includes pollen, pet dander, and other fine allergens and pollutants.
- Activated Carbon Filter: This layer contains high-grade activated carbon granules that chemically absorb various unwanted odors, including cooking smells, smoke, volatile organic compounds (VOCs), and pet odors.

5. Maintenance
Regular filter replacement is crucial for maintaining optimal air purification performance.
Filter Replacement Schedule:
It is recommended to replace the JORAIR D09 Replacement Filter every 3 to 6 months. The actual lifespan may vary depending on the existing air quality conditions and frequency of air purifier use.
