Cleaning your Dehumidifier

Humidity can lead to mold and bacteria growth which affects the air quality of your house as well as make it difficult for those with allergies or asthma sufferers. Luckily, there are some simple steps you can take to keep your dehumidifier working efficiently.

Cleaning the Filters

Cleaning the filters is the most important step in removing the dirt and dust collected by your dehumidifier. This process also involves making sure that there is no dust or debris in the air intake and outlet exhausts, which can be seen with a simple visual inspection.

If you notice any fine particles between your vents on either the front or top grills, remove them by using their release mechanism and give them a wipe down with a damp cloth.

After that, vacuum them and use steam or warm water to remove any stubborn dirt as necessary. Always make sure that they are dry before placing them back into your dehumidifier.

Cleaning the Water Collection Tank
