Pump

6 Best Whole House Dehumidifiers to Make Your Home a Healthier Place to LiveRepeatedly emptying a rapidly-filling tank is tedious enough to turn even the best portable whole house dehumidifier into a peeving burden. This is why majority of the models also come with an attachment for a drain hose which eliminates this task by diverting the water downwards to a sink or an external drainage system using gravity.

Dimensions and weight

6 Best Whole House Dehumidifiers to Make Your Home a Healthier Place to LiveMore often than not, the overall size of dehumidifiers with reservoirs matches their scope of coverage and tank capacity. Broader areas require larger tanks which can hold vast volumes of drawn moisture. This subsequently translates to big-size units.

In contrast, the best dehumidifiers for whole houses mainly incorporate drain hoses and built-in pumps for continuous drainage option to conveniently meet the dehumidification needs of an entire household without any need for frequent emptying. Pumps and other components may increase their weight, but the absence of a large tank reduces the overall dimensions of these units into a more maneuverable size.

Ultimately, the ideal size and weight should be determined by the amount of space available for set up and whether you be moving the unit to different areas.

Handles and wheels

Noise level

Dehumidifiers use fans which generate varied levels of noise depending on their size and speed. This noise is amplified in mechanical models due to the buzz and vibration of pumps, compressors, and other movable parts.

Look for noise level, measured in decibels that does not exceed 60 decibels and adjustable fan speeds that lets you switch to a lower setting to reduce the noise. A good example is the TOSOT 70 Pint Dehumidifier which produces 52, 50 and 48 decibels of noise when operating on high, medium and low fan speeds respectively. Considering 50 decibels is akin to a normal conversation, all its 3 speeds are fairly unobtrusive.
