ALORAIR builds dehumidifiers for spaces most units can’t handle. The Sentinel WHD100 is engineered for the long haul in areas like sealed crawl spaces and basements, where consistent moisture control is structural, not just comfortable. This is a commercial-grade appliance designed to run continuously and quietly protect your property.

It moves a serious amount of air for its size. The 90-pint per day capacity (at AHAM standards) means it can manage moisture in areas up to 2,300 square feet. It pulls water from the air efficiently, using less energy than older compressor-based models you might find at a big-box store. You set your target humidity level and it works in the background, maintaining that condition without constant cycling on and off.

Installation requires a dedicated drain line and proper electrical connection, so factor in professional help if you’re not comfortable with that. This isn’t a portable unit you plug in next to the laundry. For a damp, enclosed space that needs a permanent, set-and-forget solution, the Sentinel is built to be that solution for years.
