AlorAir Sentinel HD35P Crawlspace Dehumidifier with Pump

For a smaller crawlspace or basement, up to about 1,000 square feet, the Sentinel HD35P is the approachable starting point. It removes up to 35 pints of moisture a day under standard AHAM test conditions (up to 70 pints a day in saturated air), and its built-in pump means it doesn't depend on a floor drain.

The pump can push water up to 19.6 feet, up or sideways. Both a pump hose and a gravity hose come in the box, so it can also drain by gravity where that is possible.

• Up to 35 pints/day (AHAM); up to 70 pints/day at saturation
• Covers up to about 1,000 sq ft
• Built-in pump with 19.6 ft lift, or gravity drain (both hoses included)
• Runs from 33°F to 105°F, with automatic defrost
• Compact 15.2" L x 11.2" W x 11.4" H, about 38 lb, with a top handle
• 6-year limited warranty, with the first 2 years full coverage

Three steps before you buy: identify where the moisture is coming from, size the dehumidifier to the space, and plan where the water will drain. A dehumidifier is most effective as part of a dry, sealed crawlspace, and a qualified contractor can help with all three.
