Considerations When Buying Dehumidifier

#1 Application

As the small area, home or office normally uses small dehumidifier up to 25L/Day.

For basement, outdoor greenhouse,factory, or certain project, uses dehumidifier from 30L up to more than 1,000L/Day.

Commercial Dehumidifier-90E

#2 Type

Normally 3 types dehumidifier: refrigerant, desiccant, and semi-conductor dehumidifier.Refrigerant dehumidifier is popular used in office, room,small and medium building or project; desiccant dehumidifier used in very small spaces, like cabinet,drawer,where refrigerant dehumidifier can’t place or work, Or in very big project like workshop, shopping mall, ;semi-conductor dehumidifer’s capacity commonly is less than 10L/Day, it also can use in small room or office, but it’s cheaper than refrigerant dehumidifier.

#3 Auto-defrost

This feature can be important if you plan to use the dehumidifier in a cooler environment. Auto-defrost prevents the unit from freezing up and ensures it can continue to operate effectively.

#4 Humidity Level

Consider the current humidity level in your space.

Some dehumidifiers have adjustable settings to target specific humidity levels. If you live in a particularly humid area, consider choosing dehumidifier with a higher capacity or one specifically designed for high humidity environments.

#5 Water Removal Option

Dehumidifiers collect water extracted from the air, and the collected moisture needs to be removed. Check if the dehumidifier has a built-in water tank or if it offers continuous drainage options. Some models may include a pump for convenient water removal, which is particularly useful if you need to drain the water upwards or over longer distances.

#6 Function

Some clients like touch panel not button control, we will recommend the suitable model.
We have more options like WIFI control, Color panel, AI control, Memory function, also can customize your design as your drawings, contact us freely.

#7 Size and Capacity

The size of the dehumidifier will depend on the size of the room and the level of humidity. Dehumidifiers come in various sizes and capacities, so it’s important to choose one that can effectively remove moisture from the air in your space.

#8 Pricing

Dehumidifiers can range in price from under $100 to over $500, so consider your budget when choosing a model.

According to different price rates, you can choose different types dehumidifier.Like in shopping mall, you can choose commercial
dehumidifier or several pieces home dehumidifier, both of them can match the dehumidification areas. Or in the same room size, you can choose less capacity of dehumidification equipment, as the price is cheaper.

Keep in mind that higher-priced dehumidifiers may have more features and a longer lifespan.

#9 Reputation

Before confirming the order, should first verify the authenticity of supplier, if possible please visit the factory before purchasing
the products, what’s more, can ask for some sample for testing then you will have a brief understanding about this company and their managenment.

#10 After-sale Service

As a wholesale supplier, probably you will need technical help for after-sale, so if you can get continuous support from dehumidifier manufacturer is very important. Sometimes clients need to replace new spare parts as well, contact us for better support, please.

The FAQs

Frequently Asked Questions About Dehumidifier

You may need a dehumidifier if you live in a humid climate, have excess moisture in your home, experience condensation on windows, notice musty odors, or have issues with mold and mildew growth. Dehumidifiers help create a more comfortable and healthier indoor environment.

Dehumidifiers work by drawing air into the unit and passing it over cooling coils. As the air cools, moisture condenses, and the water is collected in a tank or drained out. The dehumidifier then releases the drier air back into the room.

Place the dehumidifier in an area where moisture is a problem, such as basements, bathrooms, laundry rooms, or any other spaces prone to high humidity. Ensure proper air circulation around the unit and avoid blocking the air intake or exhaust vents.

The size of the dehumidifier is typically determined by the room’s square footage and humidity levels. You can refer to the manufacturer’s guidelines or use online calculators that consider these factors to determine the appropriate capacity or pint-per-day (PPD) rating for your needs.

The frequency of emptying the water tank depends on the dehumidifier’s capacity and the humidity levels in your space. Smaller dehumidifiers may need to be emptied daily, while larger units with higher capacities may require less frequent emptying.

Yes, some dehumidifiers are designed to operate in colder temperatures. Look for models with an auto-defrost function that prevents frost buildup on the coils. This feature allows the dehumidifier to continue operating efficiently even in colder environments.

Regular maintenance involves cleaning or replacing the air filter, emptying and cleaning the water tank, and periodically inspecting the unit for any signs of damage or malfunctions.

Refer to the manufacturer’s instructions for specific cleaning and maintenance guidelines.
