Choosing The Right Dehumidifier

Deciding to invest in a dehumidifier is a smart move for your home or office, but determining the right size for your space can be confusing.

Skip to the sizing chart here.

Don’t worry, it’s easier than it seems, and we’ve outlined the essential steps below:

Starting Point - Understanding Dehumidifier Sizing:

The size of a dehumidifier is determined by its total moisture removal capacity. This capacity is measured in litres of moisture removed from a space in a 24-hour period. For instance:

We offer 5L10L12L, 20L and a 25L dehumidifier, meaning they can extract 5L, 10L, 12L, 20L & 25L of moisture from the air in a day, under test conditions of 30°C and 80% relative humidity (RH).

To make an informed choice, start by considering the number of bedrooms in your property.

Other Important Factors:

  • Property Level: Whether your property is single or double-storey - you will need a dehumidifier for each level, suited to its size.

  • Occupancy: The number of people residing or spending time on the property significantly affects its humidity, as people produce moisture, increasing humidity. A 10L to 12L dehumidifier is suitable for a family of 2-3, while a larger family may require a 12L to 20L dehumidifier.

  • Quick Tips:

    • Add 5L for a humid climate.
    • Add 5L if multiple people will be in the home.
    • Add 5L for multiple south-facing external doors and windows.
    • Add 5L if a washer and dryer are nearby.

    Refer to the chart below, considering the conditions of your space and the dehumidifier’s capacity.

    Hi, I have a holiday & only access the property now and then. Ive been looking at the UD30l for my house. What I would like to know if if I can set it to the Smart Mode and will this allow the machine to continue to work while we are away from the house? I will ensure that I have the auto drainage system installed.
