What Size of Dehumidifier Do You Need?

Defined Tag: Basement Dehumidifiers.
Moisture and dampness can come from various sources. It can be from the floors and/or walls (infiltration), exhale moisture from household members, from open doors and windows, or it can be from dryers and things that dry naturally.

To choose a dehumidifier that best suits your house, and to find the right size of dehumidifier, we will need to put all the moisture load into consideration. Dehumidifier sizing depends on the volume of water extracted from air in 24 hours. It is worth noted that having a wrong model in wrong place, such as having a small-capacity model in a large room, can result in an unacceptable humidity level.
For detailed information regarding the size of dehumidifier you need, please refer to the dehumidifier sizing chart.

Please keep in mind that you should always choose a higher output dehumidifier than it is shown in the table in order to get the best result.

Besides, additional, and yet important, moisture source like vats of liquid was ignored in the chart. You should consult a specialist for more information for more advice if your condition doesn’t match the criteria shown in the table.

Most common sizes that fits the majority of households are 25, 30, and 40 pint models. It is recommended that a 25-pint model will best suit 1,000 square feet area under normal condition. If you need more coverage, a 40-pint model can cover up to 1,5000 square feet under normal circumstances.

If you want to see if your house falls under the so-called “normal condition”, you may need to buy a cheap humidity gauge at your local hardware store to measure the indoor relative humidity. Humidity level from 40% to 50% is considered as normal, but it can runs somewhere from 60% to 70% during summer.

You should also consider how much energy is going to be consumed by the dehumidifier besides the size issue. Dehumidifier that earns an Energy Star status means it meets the energy efficient criteria or energy factors. Dehumidifiers that earn this status are far more efficient than the standard model and can save you up to 23% of energy.
