Why is my Meaco DD8L Junior not collecting water?

C
Carmen WilliamsAug 18, 2025
If your Meaco Dehumidifier isn't collecting much water or sufficiently reducing humidity, several factors could be at play. The unit might be undersized for the area; it's designed for up to a small five-bedroom house, so a larger space may require a more powerful dehumidifier. Also, too many moisture sources, like bathing, cooking, or using a calor gas heater, can overwhelm the unit. Ensure adequate ventilation by closing windows and doors. A blocked air filter can also reduce performance; clean the air filter to ensure optimal airflow.
