What is a dehumidifier?
A dehumidifier is an essential appliance that helps to control the humidity of your home. It works by removing excess moisture from the air, thus creating a more comfortable living environment. If you are in the market for a dehumidifier, the first step is to determine which type is best for your needs. So read on to find out which size is best.
What is dehumidifier size?
What is the true measure of a dehumidifier's size? It's not about physical dimensions, but rather the litres of water it can extract per day, which is known as its 'extraction rate'. This is measured as the amount of water the dehumidifier can extract from the air within a 24-hour period, when operating at a certain temperature. So when we say that a dehumidifier has a size of 12L, what we really mean is that it has an optimal daily extraction rate of 12 litres of water. Although larger capacity models are typically bigger, it's important to note that size doesn't always directly relate to capacity.
The tank capacity, which is typically between 2-6L, is separate from the extraction rate. It is important to note that the tank size is usually smaller than the daily extraction rate. However, this does not mean that you will need to empty the tank multiple times per day. It will be dependent on how much humidity you have present in your home and the daily temperature.
How to choose a size?
Every brand specifies the extraction rate of their machines, which serves as a useful measurement for comparing different models. However, it's important to note that this number represents the maximum extraction achievable under ideal conditions. When it comes to dehumidifiers, their effectiveness is not solely determined by their stated extraction rate. Factors such as temperature and humidity play a significant role in how much moisture they can extract from the air. However, this doesn't mean that their extraction rate should be overlooked. Generally, the higher the extraction rate is, the better equipped the unit is to handle bigger spaces and higher levels of moisture. If you only need to manage humidity in a small room with mild dampness, a low extraction rate such as 8 - 10L might suffice. However, if you're looking to dehumidify multiple rooms or an entire house, opting for a dehumidifier with a larger extraction, such as a 20-30L is essential.

Which dehumidifier is best for bathrooms?
A dehumidifier is an electrical device, so it's important to be careful when using it in a wet environment like a bathroom.

The best spot to place your dehumidifier for extracting moisture from a bathroom is in the hallway or landing, by the bathroom door.
