4. Operating Principles
Once the filter is correctly installed and the air purifier is powered on, air is drawn into the unit through the intake vents. It then passes through the 3-stage filtration system:
- Larger particles are trapped by the pre-filter.
- Microscopic particles are captured by the H13 True HEPA filter.
- Odors and harmful gases are absorbed by the activated carbon filter.
Clean, purified air is then released back into the room, improving overall air quality.
5. Maintenance
Regular filter replacement is crucial for maintaining the efficiency of your AMEIFU F2 air purifier.
Filter Replacement Frequency
It is recommended to replace the HEPA filter every 3-6 months. This duration may vary depending on air quality, usage frequency, and environmental factors (e.g., presence of pets, smoking, pollution levels).
Filter Reset Indicator
Your AMEIFU F2 air purifier may feature a filter reset indicator light. After replacing the filter, consult your air purifier's main user manual for instructions on how to reset this indicator.
