Airflow is blocked or the filter is clogged.
- First, check the physical space. You need at least 15 inches of clearance on all sides. Move it away from walls, curtains, and furniture.
- Clean the pre-filter. Hair and lint clog it fast, strangling airflow. Remove and rinse it.
- Verify the main HEPA filter is installed correctly and all plastic packaging is removed. A wrapped filter stops air completely.
- Tap the fan speed button to ensure you're actually on speed 4 or Auto mode.
If that didn't work, the filter may be saturated and need replacing. If airflow is still weak after all this, a foreign object might be blocking the fan. Do not try to disassemble it. Contact support.
