All the information you need to know about dehumidifiers.

What is relative humidity?

Relative humidity is the percentage of moisture in the air compared to the maximum amount the air can hold at a specific temperature. When the air is warm, it can hold more water vapor; when it's cool, it holds less. For example, 70% relative humidity means the air contains 70% of the moisture it could potentially hold at that temperature. It’s a key factor in comfort, indoor air quality, and the effectiveness of appliances like dehumidifiers.

Where does the water come from?

The water in a dehumidifier comes from moisture in the air. As humid air passes through the unit, it cools down, causing water vapor to condense into liquid, which is then collected in a tank or drained away.

What is the ideal humidity level for my home?

The ideal humidity level for a home is typically between 40% and 60%. This range helps maintain comfort, prevents mold growth, and protects furniture and electronics. Levels below 40% can feel too dry, while levels above 60% may encourage dampness and allergens.

How does a dehumidifier work?

A dehumidifier works by removing excess moisture from the air to reduce humidity levels. It draws in humid air using a fan, then passes it over cold coils. As the air cools, the moisture condenses into water droplets, which are collected in a tank or drained away. The dry air is then reheated slightly and released back into the room, helping maintain a comfortable and healthy indoor environment.

How long will it take to get the moisture under control?

A dehumidifier typically starts to show noticeable results within a few hours, depending on the room size, humidity level, and the unit’s capacity. In very damp spaces, it might take 12 to 24 hours to bring humidity down to a comfortable level. For ongoing effectiveness, it’s best to run the dehumidifier continuously or on a humidity-controlled setting until the desired level is reached.
