Frequently Asked Questions When Buying a Dehumidifier

Choosing a dehumidifier can be a difficult purchasing decision. To help you choose the best dehumidifier for your needs, DeAir has compiled a list of frequently asked questions that you should consider before buying.

Basic factors to consider

When choosing to buy a dehumidifier, there are some basic factors you need to know:

• What is the area of ​​the area that needs dehumidification? (Including height and adjacent open areas)
• What area do you live in? (Affects outdoor air humidity)
• What is the current temperature in the area that needs dehumidification?
• What is the current humidity in the area?
• What is the appropriate humidity level you want to achieve?

Where and What You'll Use Your Dehumidifier

Where you'll be placing the dehumidifier and what you'll be using it for will affect the type of dehumidifier you'll need:

• Which areas will be dehumidified? (Bedrooms, offices, basements, warehouses...)
• What is the dehumidifying area used for? (Work, storage, rest...)

Other factors to consider

• Noise control? (Especially important for bedrooms or offices)
• Does the list of brands and types of dehumidifiers matter? (Consider reputation and performance)

1. How big is the area that needs dehumidification?

The first thing you need to know is the area that needs dehumidification. Remember that you need to take into account the height of the area, as you will be drying the air throughout the space.
Furthermore, when figuring out the area of ​​this area, it is necessary to take into account the entire extension area. This includes any adjacent rooms that will open into the area where the dehumidifier will be located. background-color: #ffffff;">. The reason is that the humidity in the air always ensures balance, by moving from places with high humidity to places with low humidity. So if you plan to dehumidify an area of ​​200m22 for your basement and the door opens to another area of ​​100m2, then you should plan to dehumidify for 300m2, unless you close that door and prevent outside air from coming in. If you run dehumidifier in the basement and through the doors on the first and second floors, you're essentially dehumidifying the entire house. If the windows on the first and second floors are open, you're dehumidifying the entire neighborhood

2. Which area of ​​your country do you live in?

The area you live in will indicate the humidity of the air outside and thus indicate what percentage of humidity needs to be removed. With the climate in Vietnam, if you live in the North, the need for dehumidification is most necessary in the summer and spring. These two seasons are the two rainy seasons, so the humidity is often above 85%. However, Vietnam is a country with a hot and humid climate, so the average humidity is usually at 80%. The two regions of the South and the North have different climates but generally have similar humidity.

So like any device, you should have a plan on how much money to spend on this product. Obviously, if the need to use it only lasts for 1-2 months, you should not buy a dehumidifier that is too expensive. On the other hand, if you have to use it regularly like in Vietnam, you should consider buying a dehumidifier good for long-term use such as: Olmas, DeAir dehumidifier

3. What is the current air temperature and humidity in the room where the dehumidifier is located?

This is an important factor for purchasing dehumidifier. From that result, you will determine the type of dehumidifier needed. Most dehumidifiers will work well when the air temperature fluctuates between 22-30 degrees Celsius. If the temperature is too high or too low, it will also affect the quality of dehumidification and the condition of the machine.
Humidity exceeds 60%, a dehumidifier is the right choice. If the humidity is too high, you will need a machine operate at a higher capacity.

4. What is the appropriate humidity level you need?

In most cases, if you are in an area with high humidity above 60%, you will be at risk of respiratory diseases and skin diseases caused by bacterial growth. Humidity above 55% is also an opportunity for mold to grow, which can cause damage to furniture and machinery in the home and business.
Therefore, we recommend that you reduce the humidity to the level50% to eliminate potential hazards. However, adjust the humidity to suit your body, should not be too low below 40%. An exception is to protect musical instruments such as organs, pianos.. the safe humidity is 45%. (The ideal humidity for musical instruments is 45-55%)

5. Which areas will be dehumidified?

This is an important issue to consider because each location where the dehumidifier is placed will have different humidity and temperature.
If you plan to keep it in your bedroom, you should choose a dehumidifier that operates more quietly, without making as much noise as other types of machines.
If you are buying for a storage space for machinery, important data or military equipment… then it will have to fit in an area with low ceilings as well as be powerful enough to remove moisture. Especially if the floor is dirt and not sealed. These types are usually  industrial dehumidifier with high capacity like: dehumidifier DeAir

If one is planning to run a dehumidifier in the basement, one needs a relatively large capacity dehumidifier. Since this area usually has higher humidity and relatively low air temperatures, one should also look for some special types of dehumidifiers that the industry calls low-temperature dehumidifiers.

6. What is the main purpose of this area?

Some musical instrumentsmusic will require a humidity level of 45%.
If you're just looking to prevent mold and mildew in your basement, a humidity level of 50-55% is ideal.
If the area is used for recreation, 40-50% is to create a comfortable environment for your company.
Other factors that contribute to the appropriate humidity are human activity or the presence of doors and windows. For example, if it is a gym, one must take into account the additional humidity in the air from people sweating and exhaling. In addition, if there is an indoor swimming pool or aquarium, the humidity will also increase due to water evaporating into the air. In these two situations, we recommend that you contact the company's consultants for assistance.

7. How to control the noise level?

If  is operated while people are working in the office or resting in the bedroom, you should choose to buy the machine with the lowest noise level. All dehumidifiers will have a different noise level due to the operation of the compressor. Some compressors when operating will create uneven noise and cause earache for the user. Try it to see if you accept it.Get the noise level of what type of machine. Types of home dehumidifiers will have less noise than the device : initial; background-attachment: initial; background-origin: initial; background-clip: initial; margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline;">industrial dehumidifier. Because the capacity is smaller.

8. Is the list of dehumidifier options really important?

Most people will find this important because it is one of the factors that determine the quality and price of the product.
However, you should also know that a dehumidifier Just because an appliance doesn't come with an energy rating label doesn't mean it's bad in terms of energy consumption. This is because not all manufacturers will spend the money to go through the approval and testing process to get the certification. It's best to add an energy-saving device to all the appliances in your home and business to reduce costs and save on energy consumption.
