4. Product Components and Filtration System
The CA-509Pro SMART utilizes an advanced 8-step filtration system to ensure comprehensive air purification:
- Air Intake: Polluted indoor air is drawn in by the silent fan.
- Smart Particle Sensor: Measures and automatically regulates air quality.
- Pre-filters (2x): Capture larger dust particles, hair, and pet dander.
- HEPA H13 Filters (2x): Filter 99.97% of all suspended particles down to 0.3 microns, including fine dust, pollen, allergens, and mold spores.
- Activated Carbon Filters (2x): Effectively remove gases, chemicals, cigarette smoke, VOCs, and odors.
- UV-C Lamps (2x): Ultraviolet light (254 nm) kills harmful microorganisms such as germs, bacteria, fungi, and deactivates viruses.
- Ozone-Free Ionizer (2x): Distributes over 4,000,000 negative ions/cm³ to neutralize harmful substances and odors.
- Purified Air Output: Clean, fresh air is released into the room.
