Where Should I Place My Dehumidifier? A Comprehensive Guide to Perfect Placement

Dehumidifiers play a crucial role in maintaining indoor air quality by reducing excess moisture levels. They work exceptionally well in areas like kitchens, baths, and basements that are prone to high humidity. But it’s crucial to position your dehumidifier correctly for the best results.

Importance of Proper Placement

A dehumidifier’s performance is primarily determined by its place in a space. Its optimal positioning enhances its effectiveness and guarantees consistent elimination of moisture across the room. Ineffectiveness and even possible appliance damage might result from improper placement.

Factors to Consider Before Placing a Dehumidifier

Room Size and Layout

When choosing where to put your dehumidifier, the room’s dimensions and design are essential factors to consider. Numerous units or carefully positioned appliances may be needed to efficiently lower humidity levels in larger areas.

Humidity Levels

It is essential to know the room’s present humidity levels for placement. Higher humidity areas must be closer to the moisture source or run continuously to maintain the right conditions.

Source of Moisture

Determining the room’s primary moisture source is crucial for targeted installation. Leaky pipes, water intrusion, and insufficient ventilation are typical causes. By positioning the dehumidifier close to these sources, you can lessen the chance of mould growth and moisture accumulation.

The best places to put a dehumidifier are close to the moisture source

Indirect moisture removal is ensured by positioning the dehumidifier close to the source. For instance, placing the appliance close to the afflicted area in a basement with a water leak will assist in stopping additional damage and mould growth.

Central Areas of the Room

The dehumidifier should be positioned in the middle of the room to encourage equitable distribution of dry air. This keeps humidity levels steady and moisture from building up in places that aren’t noticed.

Elevated Surfaces

Increasing the dehumidifier’s overall efficacy and airflow is possible by raising it off the ground. When placed on a sturdy table or shelf, the appliance is less likely to sustain damage from unintentional spills or floods.

Avoiding Common Mistakes in Placement

Placing in Closed Spaces

Keep the dehumidifier out of enclosed areas like cupboards or closets because this impedes ventilation and makes it less effective at removing moisture from the air.

Blocking Airflow

Make sure there is enough space around the dehumidifier to permit appropriate ventilation. Vents and intake/exhaust ports should not be blocked as this might reduce performance and increase energy usage.

Tips for Optimizing Dehumidifier Efficiency

Regular Maintenance

Regular maintenance, such as cleaning coils and filters, guarantees optimum performance and increases the dehumidifier’s lifespan. For suggested maintenance intervals, refer to the manufacturer’s guidelines.

Monitoring Humidity Levels

Utilize a hygrometer to check humidity levels and modify the dehumidifier’s settings periodically. Relative humidity should be kept between 30 and 50% to ensure comfort within and stop mould growth.


It must be appropriately placed to get the most out of your dehumidifier and maximize its ability to regulate indoor humidity levels. You can guarantee optimum performance and create a healthy indoor environment by considering elements like room size, humidity levels, and the source of moisture.


Can I place my dehumidifier in a closet?

Putting a dehumidifier in a closet is not advisable since this will limit ventilation and make it more difficult for the device to extract moisture from the air.

Should I keep my dehumidifier running all the time?

The humidity in the space and other variables affect how long your dehumidifier will run. For best results, it’s best to keep an eye on the humidity levels and modify the settings as necessary.

Can I place my dehumidifier on carpeted floors?

Although a dehumidifier can be set on carpeted flooring, raising it off the ground on a stable platform is best to increase ventilation and guard against spills or flooding.

How often should I clean my dehumidifier?

The secret to achieving peak performance is routine maintenance. As directed by the manufacturer, clean coils and filters usually every few months.

What should I do if my dehumidifier isn’t working effectively?

If your dehumidifier isn’t working as it should, ensure it’s placed correctly, look for any airflow obstructions, and consider the room size and humidity levels. If problems continue, refer to the troubleshooting manual provided by the manufacturer or get expert help.
