When it comes to choosing a dehumidifier, estimated the correct size is crucial to getting the job done. Getting one that’s too small will mean moisture problems will persist, while buying one too large means overpaying. Here are some answers to the most commonly asked questions to help you determine whether you should be looking at large or small dehumidifiers.
Dehumidifiers are rated by the maximum amount of humidity or moisture that they will remove from the air in a 24 hour period.
For example, a 40 pint dehumidifier is graded to remove 40 pints of moisture from the atmosphere in a 24 hour period. Keep in mind that although the dehumidifier may be eliminating 40 pints of moisture a day the unit may only have a 25 pint storage tank so you’ll have to manually empty the reservoir bucket in order to get the unit’s maximum capacity. To avoid this problem you would need to purchase a unit that supplies a direct drain option so the unit may continuously expel the moisture into a nearby drain on your region negating the need to manually empty the holding tank.
Which model would minimize operating costs?
Start by selecting a unit which is “Energy Star” rated. The Energy Star rating is an international designation suggesting that an appliance has been deemed energy efficient.
The dehumidifiers that provide this designation are clearly marked on our site. You will also need to make certain that you do not pick a dehumidifier that is too small for the area you would like to cover and the humidity level that you would like to maintain. An undersized dehumidifier will operate more often which will subsequently use more energy than a correctly sized unit.
Do they generate heat?
Yes, a dehumidifier will add some heat into its immediate surroundings. The quantity of heat will vary greatly depending on the size of the unit and the place it’s operating within.
The warmer the temperature the device is operating within the more efficiently the unit will be able to remove moisture from the air. It’s conceivable in smaller areas that a dehumidifier may raise the ambient temperature 5 to 8 levels. Conversely, a dehumidifier will cease to function if the environment becomes too cold.
This is an important element to consider if you are attempting to dehumidify a basement area that’s not heated. Check the specifications of this unit you’re considering to learn more on the units operating parameters.
What is the lowest temperature dehumidifiers can operate in?
Most residential dehumidifiers can operate in temperatures between 41-44 degrees. Industrial desiccant dehumidifiers function in subzero temperatures. Since each unit disagrees be sure to check the specifications to search for the specific operating temperature.
What is a drain spout?
For dehumidifiers that don’t have a pump, they sometimes have a drain hose which uses gravity to help drain the water. By placing the dehumidifier higher up, the drain hose can be connected to permit water to flow down and out into a sink, tub, or outside. It’s important to remember that since the water removal relies on gravity it can only flow downwards, not vertically, like a dehumidifier with a built in pump.
Making Your Decision
Compact and portable versions of the bigger components, mini dehumidifiers are the perfect solution for smaller spaces, like bathrooms or laundry rooms, or for people with significant allergies who may have to travel with their unit. These are much more versatile as they can be places anywhere moisture builds up in your house or office and are still different.
Consider how much moisture there is…
The best way to find the ideal dehumidifier for your home or warehouse space is to understand how much work it will do. Relative humidity measures the absolute highest levels of water vapor in the atmosphere (100 percent relative humidity meaning that the air can hold no more moisture, meaning it’s raining or foggy); if relative humidity is below 30 percent the air often feels dry, and when it is over 50 percent it’ll feel really muggy and uncomfortable. The most comfortable relative humidity levels are approximately 35 to 40 percent. To gauge the humidity in your house, you can buy a hygrometer and decide what course of action you should take based on the findings.
Consider the size of the space…
Dehumidifiers come in a range of sizes, usually dependent on the amount of space in the room and moisture you will need to extract from the atmosphere–measured in pints extracted per 24-hour period. The Association of Home Appliance Manufacturers has recommendations for dehumidifiers that range from 10 pints for up to 500 square feet of space with relatively low humidity all the way to 44 or more pints for extremely wet or humid conditions in regions over 2,500 square feet.
