Why is my Perfect Aire 3PFD22 Dehumidifier not drying the air properly?
- DDawn CastilloAug 6, 2025
If your Perfect Aire Dehumidifier isn't drying the air adequately, first allow 24 hours for changes in humidity. Ensure no curtains, blinds, or furniture block the unit's front or back. Check that the set humidity percentage is lower than the room's current humidity; try running it on CONT. mode for 24 hours. Confirm all doors, windows, and openings are closed securely. Note that room temperatures below 5 °C (41° F) can affect performance, as can the presence of a kerosene heater or other sources of water vapor.
