Hampton Bay Hb40 Dehumidifier Specs

Dan Ketchum

Until the first decade of the 2000s, Hampton Bay, a brand exclusive to Home Depot, offered a line of dehumidifiers. Among these, the HB40 stood as its mid-range model. Though Hampton no longer produces humidifiers, Home Depot stocks options from Danby, DeLonghi, LG Electronics, SPT, Soleus and Zenith, among others.

Physical Specs

As its model number implies, the HB40 has a capacity of 40 pints, or 18.9-liters; this means it removes 40 pints of humidity from the air each day. This product has a light gray, somewhat glossy metal finish. The unit rolls on four plastic wheels and features front-facing vent slats. Its top-mounted control panel consists of a humidistat dial, fan speed switch and indicator light. Hampton Bay's HB40 measures 13.5 inches wide, 17.5 inches long and 22 inches tall. The unit weighs 51 pounds.


The Hampton Bay model HB40 dehumidifier features a variable humidistat with a range of eight humidity settings. A choice of high- and low-speed fan settings adds further control options. This dehumidifier comes equipped with an automatic light that turns on when the unit's bucket is full. Additionally, the HB40 features an automatic defrost function and a slide-out filter for easy cleaning.

Consumer Advocates Weigh In

In June of 2002, the nonprofit reviewers at "Consumer Reports" gave the Hampton Bay HB40-N, the unit's latest revision, a “Very Good” rating, noting its ready-to-use functionality. However, the organization reported that the dehumidifier had trouble restarting after a brownout -- a partial, short-term blackout -- and that the container was difficult to remove. Canada's Office of Energy Efficiency reports that the HB40 removed 1 liter of moisture per kilowatt hour, placing it at the low end of energy efficiency ratings.


Perhaps spurred by recalls of 2,000 HB50 dehumidifiers in 2009, Hampton Bay has since shifted solely into the production of lighting fixtures and ceiling fans, exclusively available at Home Depot stores. When the HB40-N was in stores in 2006, it retailed for about $180. As of 2011, a secondhand model could be purchased for as little as $30.
