Ideal-Air Dehumidifier 22 Pint - Up to 30 Pints per Day

Ideal-Air 22 Pint Dehumidifier — Compact Humidity Control Up to 30 Pints Per Day

For a small grow tent, propagation area, or a single-room home garden, the Ideal-Air 22 Pint Dehumidifier delivers reliable, portable humidity control without the footprint or cost of a larger unit. AHAM-rated (80°F, 60% relative humidity), it removes up to 30 pints of moisture per day under favorable conditions.

A removable washable filter, built-in handles and wheels, low-temperature defrost, and the option to plumb for permanent drainage round out a unit built for minimal day-to-day maintenance in a compact package.

Key Features & Benefits

• 22 Pint AHAM Rated Capacity: Rated at 80°F and 60% relative humidity, with removal capacity reaching up to 30 pints per day under warmer, more humid conditions.
• Removable Washable Filter: Skip disposable filter costs — clean and reinstall for continued rated airflow.
• Low Temperature Defrost: Prevents coil icing during cooler-temperature operation, keeping performance consistent in less-than-ideal room conditions.
• Compact and Mobile: Built-in handles and wheels make repositioning easy in a tight grow tent or small room.
• Permanent Drainage Option: Plumb for continuous drainage to skip manually emptying the 3-liter reservoir.

Frequently Asked Questions

What does AHAM-rated mean for this dehumidifier's capacity?

AHAM (Association of Home Appliance Manufacturers) rates dehumidifiers at a standardized 80°F and 60% relative humidity, which is more conservative than the warmer test conditions some manufacturers use. That standardization is what lets you compare this unit's capacity fairly against other AHAM-rated dehumidifiers.

How often will I need to empty the water reservoir?

The 3-liter reservoir's fill rate depends on your room's humidity level, so a high-humidity space can fill it within hours. Plumbing the unit for permanent drainage removes that maintenance step for hands-free, continuous operation.

Does this dehumidifier work well in a cooler grow tent?

The built-in low-temperature defrost helps it keep running in cooler conditions, but efficiency generally drops once temperatures fall below roughly 60-65°F. Check the minimum operating temperature spec before planning to run it in an unheated space.

When should I use a surge protector with this unit?

Use one anytime the unit sits on a circuit prone to outages, since a power surge when electricity returns can damage the circuit board — damage that isn't covered under warranty. Ideal-Air recommends a dedicated circuit with surge protection as standard practice.
