Whole house dehumidifiers are the most expensive models, costing between $1,000 and $2,000. They typically are fixed units professionally installed and connected to existing ductwork in a home’s central air or heating system.

Portable dehumidifiers, which you simply plug in, are the most popular models, available at big box hardware stores and major home improvement centers. Advances in technology have made these dehumidifiers easy to use, affordable, and effective at improving your home’s air quality.

But not all portable dehumidifiers are the same. The bottom line is to pick a unit that is efficient and effective at reducing indoor humidity and keeping it at optimal levels.
