4. Filtration System
The Trucozie T555 utilizes a 3-in-1 filtration system for comprehensive air purification:
- Pet-Specific Pre-Filter Cotton: Located at the air inlet, this filter rapidly traps large particles like pet hair, dander, and dust, preventing them from re-entering the air and extending the life of subsequent filters.
- H13 True HEPA Filter: Captures 99.97% of airborne particles as small as 0.3 microns, including smoke, pollen, fine dust, and pet dander.
- Activated Carbon Filter with Bio-Enzymes: Effectively absorbs and breaks down various odors, such as pet odors, litter box smells, cooking fumes, and cigarette smoke.
