In humid weather, dehumidifiers become a "life-saving tool" for many households. But do you know that improper usage habits can 

cause electricity bills to rise secretly? Master these 5 easily overlooked energy-saving tips, which can not only keep you dry and 

comfortable but also save electricity and money effectively. 

1. Select the appropriate dehumidification capacity based on the size of the space to avoid 

"overloading the machine with insufficient capacity".

The dehumidification capacity of dehumidifiers usually ranges from 50L/D (liters per day) to 1000L/D. The key principle is: matching 

is the foundation of efficiency.

Small rooms (such as bedrooms, study rooms): Select a model with a capacity of 50L/D to 150L/D to meet the needs. Using a machine 

with an excessively high dehumidification capacity will cause frequent start-stop operations, which not only consumes a lot of electricity 

but also shortens the machine's lifespan.

Large spaces (such as entire houses, basements): Consider models with a capacity of 200L/D or above.

Before purchasing, be sure to choose a product with the appropriate dehumidification capacity based on the usage area to prevent 

energy waste from the very beginning. 

2. Close doors and windows to block the "aid" from the outside humidity

This is the most important and often overlooked point! The dehumidifier operates in a relatively enclosed space.

If the doors and windows are open, the humid air from outside will continuously flood into the room. The dehumidifier will have 

to "work hard" and will never reach the set humidity level, resulting in continuous high-load operation and a natural increase in 

power consumption. Remember: Before dehumidifying, please make sure to close the doors and windows! 

3. Set the target humidity reasonably, not too low

Many people mistakenly believe that the lower the humidity, the better. They often set the target humidity at 40% or even lower.

Scientific range: For the human body, the most comfortable range of air humidity is 50% - 60%. Within this range, the body feels 

comfortable and it can effectively inhibit the growth of mold and dust mites.

Power-saving key: Reducing the humidity from 60% to 40% requires the dehumidifier to consume multiple times more electricity. 

Setting it within the reasonable range of 50% - 60% allows the machine to pause or operate at a reduced power level once it reaches 

the target, resulting in a very significant energy-saving effect. 

4. Place it in an area with good air circulation to enhance the dehumidification efficiency

A dehumidifier is not a "decorative item" attached to the wall. Its working principle is to inhale humid air, condense it for dehumidification, 

and then expel dry air.

Incorrect placement: Placing it close to the wall or stuffing it in a corner will seriously impede the circulation of air in the intake and 

exhaust vents, resulting in a significant reduction in dehumidification efficiency and prolonging the working time.

Correct method: Place the dehumidifier in the center of the space, in an area with smooth air circulation, ensuring at least 50 centimeters 

of space around it. Let it "breathe smoothly" so that it can work at the highest efficiency. 

5. Regularly clean the filter to keep the machine in good condition

The filter at the intake of the dehumidifier will trap dust and hair in the air. If it is not cleaned regularly, the dust will clog the mesh, just 

like a person wearing a mask when breathing, resulting in poor air intake.

Consequences: It not only affects the dehumidification effect but also increases the load on the fan and compressor, leading to increased 

power consumption.

Suggestion: Check and clean the filter at least once a month. Just rinse it clean with water and let it dry thoroughly before reinstalling it. 

This simple action can maintain the optimal performance of the dehumidifier and is the foundation for energy conservation. 

Conclusion

Dehumidifiers are power-hungry appliances, but with the right usage methods, they can achieve twice the result with half the effort. 

To sum up, there are five key steps: choosing a matching model, creating a sealed environment, setting the appropriate humidity level, 

optimizing the placement, and conducting regular maintenance. These steps are closely interrelated. Immediately check your family's 

dehumidifier usage habits and make these small changes. This might surprise you with the electricity bill during this humid season!
