Sizing dehumidifier for attic spaces

How large is your attic?

That’s the first size to measure before figuring out your dehumidifier size. The room size, humidity level, existing HVAC system, ventilations, insulations, continuous drain outlet facility, and the source of humidity problems need to be considered to arrive at the right dehumidifier for an attic. You also must analyze the dehumidifier weight, portability, features, and noise problem.

In the world of dehumidifiers, size refers to the water removal capacity in pints. The ideal size ranges from 13 pint, 30 pint, 50 pint, 70 pint to 150 pint capacity for attic dehumidifiers. The pint capacity is measured in Pints Per Day (PPD), which refers to the amount of water the dehumidifier can extract in 24 hours.

Ideally, the room’s square feet area and pint capacity are top parameters for choosing the right dehumidifier. If you want to save on cost, effort, and energy, make sure you buy a dehumidifier with a larger pint capacity than required.

Best dehumidifier for attic

Where should you place a dehumidifier in the attic?

A dehumidifier is an indispensable piece of equipment for your humid attic. The placement and position of the attic dehumidifier play a major role in its efficiency. Even if you have an energy star dehumidifier with the best features, it will not yield the expected results if it is not located optimally.

An attic is usually a problem area with air leaks, exposed return ducts, and inconvenient, unreachable corners. Hence you need to consider the room’s size, humidity source, noise levels, dehumidifying range, post navigation features, and airflow blockages before you decide on the best location.

Experts suggest that it will be ideal if your portable dehumidifier is located as centrally as possible. The centralized positioning will ensure even dehumidification of the entire attic. But if you cannot position it centrally, the dehumidifier should be closest to the humidity source, and at least 6 inches away from items that interfere with airflow.
