Immoderate moisture in a room can contribute to the spread of mold or mildew and even lead to water damage. By lowering high humidity, dehumidifiers can avert rooms from smelling musty and protect clothes, wallpaper, electronics, and other possessions. It varies according to the different sizes of the rooms and dampness levels that require distinct sized dehumidifiers to work most efficiently. Following is the list of factors that needs to be considered while choosing the right size dehumidifier for your home.

How Dehumidifiers Work

Dehumidifiers adjust the evaporation level by drawing moisture from the air. A fan pulls the damp air into the dehumidifier and by cooling coils, which use precipitation to draw humidity from the air. The heat recovery system of dehumidifiers then course warmer, dryer air back into the room. The water is accumulated in a removable drip pain or is transmitted out of the unit with some models.

Nowadays, several dehumidifiers are equipped with a humidistat, which estimates and can set the relative moisture in a room. In summers, 50 percent RH is recommended whereas, in winter, the ideal RH can be as low as 30 percent. A whole-house dehumidifier is required if high humidity is a problem in your space. Some of the appliances are portable while others are built into and can operate as part of your HVAC system.

Desiccant dehumidifiers are specially structured to eliminate moisture from the air by using chemicals instead of condensation. They tend to be soundless and develop lower humidity levels than other dehumidifiers, but have a restricted capacity, a detectable aroma, and are less economical than other types.

Check the Room's Moisture Level

You can even use a steam meter to measure a room’s moisture or assess it based on certain general criteria as space is considered damp if it has a musty aroma in humid weather or occasionally feels damp or clammy if it has visible condensation or the ceiling or walls.

Compare Room Size vs. Moisture Level for Dehumidifier Size

The capacity of the dehumidifier is rated by the quantity of moisture removed in 24 hours, so most of the time a 30-pint humidifier is rated to get rid of 30 pints of moisture in one day.

It is essential to use a 30-pint dehumidifier for damp rooms of 500-1,500 square feet and very damp rooms of 500-1,000 square feet.

It is viable to use a 50-pint dehumidifier for damp rooms of 2,000-2,500 square feet and wet rooms of 1,000-1,500 square feet

Use a 70-pint dehumidifier if your room is very damp of 2,500 square feet, wet rooms of 2,000-2,500 square feet.

Other Factors In Selecting The Right Size Dehumidifier

Several other factors influence the evaporation of the room, so consider the following when sizing a dehumidifier:

  • If it’s a humid climate then is recommended to add 10 pints to the capacity
  • It is also advised to add 5 pints if multiple people live or spend time in the room

High moisture can lead the way to mildew and mold growth and even make your space more alluring to roaches, spiders, and other insects that prefer a moist atmosphere. Selecting the accurate size dehumidifier for your laundry room, basement, or other space in the interiors can put dew control at your fingertips.
