不同大小的房間需要不同容量的抽濕機。若選擇過大容量的機型，會造成不必要的電力消耗；相反，容量過小則可能無法有效除濕，導致長時間運行，反而更耗電。選擇時，可參考以下指引：

• 10-12公升/日（適合100-200平方尺，如小型房間）
• 12-20公升/日（適合200-400平方尺，如睡房、客廳）
• 20-30公升/日（適合400-700平方尺，如大型客廳或開放式空間）

此外，若家中濕氣特別重，可考慮具有智能濕度控制功能的抽濕機，以自動調節運行模式，避免無謂的耗電。

抽濕機的濕度設定對耗電量影響甚大。很多人誤以為應將濕度調至最低（如30%以下），但實際上，最佳的室內濕度應保持在50-60%，既可防止發霉，又能維持舒適環境並降低能耗。

建議設定濕度數值：
• 50-55%（適合日常使用，防止牆壁和衣物發霉）
• 55-60%（適合較乾燥氣候，避免過度抽濕影響皮膚健康）
• 45-50%（適合存放樂器、相機等需保持低濕度的物品）

抽濕機的擺放位置會影響抽濕效率。擺放不當可能導致循環不佳，影響除濕效果，甚至增加電費。

擺放建議：
• 遠離牆壁或傢俱（與牆面保持最少30cm距離，確保空氣流通）
• 置於房間中央（能讓空氣均勻流動，提高抽濕效率）
• 靠近濕氣來源（如浴室、廚房附近，能更有效減少濕氣）

雖然抽濕機可長時間運行，但若持續開機，會增加電力消耗並縮短機器壽命。建議使用定時功能，在濕度最高的時段（如清晨或夜間）運行6-8小時即可。此外，可配合風扇使用，加快空氣循環，達到更佳除濕效果。

水箱內的積水容易滋生細菌和霉菌，長時間不清洗可能會產生異味，甚至影響抽濕機的運作。建議：

• 每天清理水箱內的積水，避免細菌滋生。
• 每週用溫水+中性清潔劑清洗水箱，確保乾淨無異味。
• 晾乾後再放回機器內，防止內部殘留水分影響運作。

濾網是抽濕機的重要組件，主要用來過濾空氣中的灰塵和污染物。如果濾網太髒，不但會降低抽濕效率，還可能影響空氣質素。

濾網清潔步驟：
1. 先關機並拔掉電源。
2. 取出濾網，用吸塵機或軟毛刷清除灰塵。
3. 若有頑固污垢，可用溫水+少量清潔劑輕輕刷洗。
4. 晾乾後再裝回機器內。

建議每兩週清洗一次濾網，以確保最佳運作狀態。

灰塵會堆積在機身和出入風口，影響散熱和運行效率，因此應定期擦拭：

• 機身外殼：用乾布或微濕布擦拭，避免積塵。
• 出風口與進風口：用吸塵機清理，確保空氣順暢流通。

使用前應確認：
• 電源線是否完好，避免短路或電線老化導致危險。
• 水箱是否放好，有些抽濕機會在水箱未放妥時無法開機，避免運行異常。

雖然抽濕機一般較為安全，但仍建議避免在無人時長時間運行，以防：
• 水箱滿溢（若無自動停機功能，可能導致水溢出）
• 機器過熱（長時間高負荷運行可能影響壽命）
• 電線過熱（長期運行可能增加火災風險）

為了安全，抽濕機應放置在遠離易燃物（如窗簾、紙張、床單等）的地方，以減少火災風險。此外，確保機器四周通風良好，避免因散熱不佳導致機器過熱。

Different room sizes require different capacities of dehumidifiers. Choosing a model with too large a capacity can lead to unnecessary power consumption, while a model with too small a capacity may not effectively remove moisture, causing it to run for extended periods and consume more electricity. When selecting, you can refer to the following guidelines.

• 10-12 liters/day (suitable for 100-200 square feet, such as small rooms)
• 12-20 liters/day (suitable for 200-400 square feet, such as bedrooms and living rooms)
• 20-30 liters/day (suitable for 400-700 square feet, such as large living rooms or open spaces)

Additionally, if your home has particularly high humidity, consider a dehumidifier with smart humidity control features to automatically adjust its operating mode and avoid unnecessary energy consumption.

The humidity setting on a dehumidifier significantly affects its energy consumption. Many people mistakenly believe they should set the humidity to the lowest level (below 30%), but in reality, the optimal indoor humidity should be maintained at 50-60%. This prevents mold growth while maintaining a comfortable environment and reducing energy consumption.

Recommended humidity settings:
• 50-55% (suitable for daily use, preventing mold on walls and clothes)
• 55-60% (suitable for drier climates, avoiding excessive dehumidification that can affect skin health)
• 45-50% (suitable for storing instruments, cameras, and other items that require low humidity)

The placement of the dehumidifier can affect its efficiency. Improper placement may lead to poor circulation, impacting dehumidification effectiveness and increasing electricity costs.

Placement suggestions:
• Keep it away from walls or furniture (maintain at least 30 cm distance from walls to ensure air circulation)
• Place it in the center of the room (to allow for even airflow and improve dehumidification efficiency)
• Position it near sources of moisture (such as near bathrooms or kitchens, to more effectively reduce humidity)

While dehumidifiers can run for extended periods, continuous operation increases power consumption and shortens the lifespan of the machine. It is recommended to use the timer function to run it for 6-8 hours during the highest humidity periods (such as early morning or nighttime). Additionally, using a fan can help accelerate air circulation for better dehumidification results.

Water accumulation in the tank can easily breed bacteria and mold, and prolonged neglect can lead to unpleasant odors and affect the operation of the dehumidifier. It is recommended to:

• Empty the water tank daily to prevent bacterial growth.
• Clean the tank weekly with warm water and a neutral detergent to ensure it is clean and odor-free.
• Allow it to dry before placing it back in the machine to prevent residual moisture from affecting operation.

The filter is an important component of the dehumidifier, primarily used to filter dust and pollutants from the air. If the filter is too dirty, it not only reduces dehumidification efficiency but may also affect air quality.

Filter cleaning steps:
1. Turn off the machine and unplug it.
2. Remove the filter and use a vacuum cleaner or soft brush to remove dust.
3. For stubborn dirt, gently wash with warm water and a small amount of detergent.
4. Allow it to dry before reinstalling it in the machine.

It is recommended to clean the filter every two weeks to ensure optimal operating conditions.

Dust can accumulate on the body and air inlets/outlets, affecting heat dissipation and operational efficiency, so it should be wiped regularly:

• Body: Wipe with a dry cloth or slightly damp cloth to avoid dust accumulation.
• Air Inlets and Outlets: Use a vacuum cleaner to clean them to ensure smooth airflow.

• Before operating the dehumidifier, ensure that the power cord is intact to avoid risks of short circuits or electrical hazards due to aging wires.
• Verify that the water tank is properly placed, as some dehumidifiers will not operate if the tank is not securely in position, preventing abnormal operation.

Although dehumidifiers are generally safe, it is advisable to avoid running them for long periods when no one is present to prevent.
• Overflowing of the water tank (if there is no automatic shut-off feature, this could lead to spillage).
• Overheating of the machine (prolonged high-load operation may affect its lifespan).
• Overheating of the power cord (extended operation could increase the risk of fire).

For safety, the dehumidifier should be placed away from flammable materials (such as curtains, paper, and bed linens) to reduce the risk of fire. Additionally, ensure that there is good ventilation around the machine to prevent overheating due to poor heat dissipation.
