Common Questions About Dehumidifier Usage
When Do You Need to Use a Dehumidifier? – A good rule of thumb is to use a dehumidifier when your home’s humidity level exceeds 50%. For your convenience, many dehumidifiers are equipped with a humidistat which turns them on and off as necessary to maintain a desired humidity level preset by the user. This enables you to set it and forget it until the collection tank needs to be emptied.
What Size Dehumidifier Do I Need? – Most brands provide their own sizing charts to help you accurately determine what capacity you should have for a dehumidifier based on room size and average humidity levels. Ideally, you should have a minimum of 10 pints for the first 500 sq. ft., an extra 4 pints for every increment of 500 sq. ft. after that, and an extra 4-8 pints if a room gets especially humid to the point where there is standing water, such as in basements or bathrooms.
Where Should You Put a Dehumidifier? – Dehumidifiers should be placed in a central location that is slightly elevated in rooms where humidity is most prevalent. This not only allows it to evenly pull humidity from every corner but catch humidity as it settles toward the ground. Make sure all doors or windows are closed to avoid more humidity entering the space while it works.
Where Should You Not Use a Dehumidifier? – Dehumidifiers should not be placed anywhere where their fans can be blocked, or their filters clogged. This includes inside closets, under furniture, and in rooms with excessive dust or debris. Dehumidifiers also do not work efficiently in cold environments where their coils can freeze, such as basements or garages during winter.
What is the Average Lifespan of a Dehumidifier? – The average dehumidifier can last up to 10 years with proper care and regular maintenance. Empty filters for efficiency, dust coils to prevent overheating, and clean the water tank to prevent mold formation. If your dehumidifier has a continuous drainage option, ensure the hose is properly connected and clear of blockages. For seasonal storage, make sure to empty and dry all components completely and place the unit in a cool, dry place.
Are Dehumidifiers Hard to Clean? – Dehumidifiers are generally easy to clean. Follow these simple steps to make sure they operate at peak efficiency.
