Ideal-Air 22 Pint Dehumidifier | 30 Pints/Day

Under typical grow room conditions of 86°F and 80% relative humidity, which you can track using a grow room temp and humidity chart, the Ideal-Air 22 Pint removes up to 30 pints of water per day. The "22 Pint" model name reflects the AHAM test standard — the unit's real-world performance is unchanged.

A recent U.S. Department of Energy ruling now requires all Ideal-Air dehumidifiers to be rated under AHAM standards (80°F, 60% RH). The unit itself has not changed. For more information on sizing, read our guide on how to choose a dehumidifier for grow rooms.

The unit can be plumbed directly to a floor drain or utility sink using a standard drain hose connection, bypassing the internal reservoir entirely. If a floor drain isn't accessible, optional condensate pumps are available separately to move water to a more convenient drain point.

The unit features an automatic shutoff that triggers as soon as the 6-liter (12.5-pint) reservoir reaches capacity, preventing overflow. Simply remove the tank, empty it, and reinsert — the unit will resume normal operation automatically.

Yes. The Ideal-Air 22 Pint includes an automatic low-temperature defrost function that prevents ice buildup on the coils when operating in cooler conditions. This allows the unit to continue running efficiently without manual intervention.

The filter is designed for easy removal and is fully washable — simply pull it out, rinse under water, allow it to dry completely, and reinsert. Regular cleaning maintains airflow efficiency and helps prolong the life of the compressor.

Yes. The Ideal-Air 22 Pint is equipped with an auto-restart function that resumes operation at the previous settings after power is restored. This is particularly useful in grow environments where you must prepare the space for cannabis after harvesting, where unattended operation is common.
