Choosing the right size dehumidifier for your space involves a few straightforward steps. Here’s how to do it:

Step 1: Measure the Area

  • Calculate the Square Footage: Measure the length and width of the room in feet. Multiply these two numbers to get the total square footage (Length × Width = Square Footage).

Step 2: Assess Humidity Levels

  • Determine the Moisture Level: Identify whether the area is:
    • Normal: No signs of dampness.
    • Damp: Occasional condensation or musty smells.
    • Very Damp: Visible mold, persistent odors, or wet spots.

Step 3: Refer to Capacity Guidelines

  • Check Capacity Charts: For example:
    • 1,500 sq. ft. (normal conditions): 30-40 pints
    • 1,500 sq. ft. (damp conditions): 40-50 pints
    • 1,500 sq. ft. (very damp conditions): 50-70 pints

Step 4: Consider Ceiling Height

  • Adjust for High Ceilings: If your room has ceilings higher than 8 feet, add additional capacity. For every foot above 8 feet, consider increasing the unit’s capacity by about 10%.

Step 5: Select a Model

  • Choose the Right Model: Based on your calculations and assessments, select a dehumidifier that meets or exceeds the recommended capacity for your space. Look for features that suit your needs, like auto-drain options or adjustable settings.

By following these steps, you can effectively choose the right size dehumidifier for your space, ensuring optimal humidity control and comfort. Check out our range of dehumidifiers here.

What is the ideal humidity level for my home or workplace?

Whether your dehumidifier should fill up daily depends on several factors, including the size of the unit, the humidity levels in your environment, and the area where it’s operating. Here are some key points to consider:

  1. Humidity Levels: In very humid conditions, a dehumidifier may fill up its water tank daily as it works harder to remove excess moisture from the air. This is especially common in basements or areas with poor ventilation.
  2. Tank Size: Different dehumidifiers have varying tank capacities. Smaller units may fill up more quickly than larger models, so if you have a unit with a smaller tank, it might require more frequent emptying.
  3. Continuous Drainage Options: Many dehumidifiers come with the option for continuous drainage. This allows water to be directed away through a hose, so you won’t have to empty the tank manually, which can be convenient if the unit is in a high-moisture area.
  4. Operating Conditions: If your dehumidifier is consistently filling up, it may indicate that the humidity levels in your space are particularly high. In such cases, you may want to monitor the humidity with a hygrometer to ensure it remains within the ideal range of 30% to 50%.
