What you need to know about dehumidifiers

Before purchasing a dehumidifier, knowing a few things about them is essential. Read on for information about their size, capacity, draining capabilities, and costs. Once you’ve got a clear idea of what you want in a dehumidifier, you can start shopping. Here are some factors to consider before purchasing one best air purifier dehumidifier for your space.


Choosing the right size of dehumidifier is crucial. Dehumidifiers are rated according to the square footage they cover. Buying a dehumidifier that is too large will not work effectively, and a small unit will waste power. It is also important to remember that larger dehumidifiers are not necessarily more powerful. If you have a large space, it is better to purchase a larger unit than a small one.

The larger the tank capacity of your dehumidifier, the more energy-efficient it will be. Check out the Energy Factor to see how much water it can remove per kilowatt-hour. If the Energy Factor is high, the dehumidifier is more energy efficient. A smaller capacity means you may need to empty the tank more often. Choosing the right dehumidifier will help you save money on your energy bills.


A dehumidifier’s capacity is the amount of moisture it can remove from the air per day. 

The capacity of a dehumidifier is measured in pints. The larger the capacity, the faster it will remove moisture from the air. A 30-pint dehumidifier can effectively remove 30 pints of moisture a day. On the other hand, a 50-pint unit will serve a medium-sized room and a home basement. The largest-capacity units are designed for large rooms and basements. You may check this website to learn more about dehumidifiers!

Another feature to consider is ACH (air change rate). A higher ACH means a dehumidifier will cycle the air in a room in less than an hour. This feature is essential, as a high ACH means it will use less electricity and spend more time in idle mode. Manufacturers typically refer to cubic meters per hour (CFM), but consumers must convert the figure to cubic feet per minute (CFM).

Draining capability

Another factor to consider is the size of the space that you need to dehumidify. Dehumidifiers come in different capacities, and you can choose the one that best suits your needs. Some dehumidifiers can drain their contents through a drain hose. The size of the space will determine how much water the device can remove. The larger the capacity, the fewer trips you will need to make to empty it. On the other hand, larger capacity models will be heavier.

For large basements, pumpless dehumidifiers can reduce humidity in the area 24 hours a day. One model even lowered the humidity in the area to 45% overnight. 

If the bucket is filled, your dehumidifier should switch to the primary method of draining water. Make sure the hose is positioned downward and clear of obstructions. If you don’t have these two factors, the water will drain into a bucket instead of outside. Remove any obstacles to avoid a faulty float switch.


The cost of dehumidifiers varies depending on the size of the space and the relative humidity in the room. Larger spaces require more powerful dehumidifiers to control humidity levels. These appliances tend to be more expensive because they use more energy. You can save on energy costs by choosing smaller dehumidifiers. However, the smaller ones may take longer to remove moisture and run for longer. Therefore, you may end up paying more than the larger ones.

The cost of dehumidifiers depends on their capacity and their maintenance. High-quality dehumidifiers cost more upfront, but they require fewer repairs. Depending on the type and size of the machine, repairs can range from $50 to $200. Typically, a dehumidifier needs to be replaced every 3-5 years. You can do this yourself for a relatively low cost or hire a professional to install it.If you’re looking to save money, look for dehumidifiers on sale. However, don’t forget to compare prices and features between different manufacturers.

If you’re looking for a more affordable unit, check the cost of the parts. Many dehumidifiers are built using automated machinery, which adds to their price. Moreover, the operational cost of automated machinery and labour is included in the overall price. Finally, look for a dehumidifier with low noise and a warranty.
