The Breeva A2 incorporates a comprehensive filtration system to capture various airborne particles and odors:
- Pre-Filter: Captures large particles such as dust, pet hair, and lint.
- True HEPA (H13) Filter: Eliminates 99.97% of airborne particles as small as 0.3 microns, including pollen, dust mites, mold spores, and pet dander.
- Activated Carbon Filter: Absorbs odors, smoke, and volatile organic compounds (VOCs) from household cleaning supplies.
- Anion Technology: Releases negative ions to help fine particles condense and settle, further purifying the air.

Based on sensor readings, the air purifier automatically adjusts its fan speed to optimize purification, ensuring continuous clean air without manual intervention. Air quality is indicated by LED lights (Good, Moderate, Unhealthy).
