3. Product Components and Filtration System
The Airthereal AEH300 consists of a main unit, a multi-layer air filter, and a humidifier filter. The air purification system employs a 3-layer filtration process:
- Pre-Filter (Nylon Mesh): Captures large particles such as dust, lint, and pet hair.
- HEPA -suodatin: Traps fine particles like PM2.5, pollen, and pet dander.
- Aktiivihiilisuodatin: Absorbs odors, smoke, and harmful gases like formaldehyde and toluene.
