In summary, when determining what size dehumidifier is right for you consider the size of the room or home, plus:.
Energy Star-rated dehumidifiers use about 15 percent less energy than conventional units. Dehumidifiers can provide a continuous flow of fresh, dry air in the home, resulting in an energy-efficient solution that improves indoor air quality and keeps mold growth at bay all season long.
There are many reasons why running a dehumidifier in the home is a good idea. The units can reduce allergy symptoms and other health issues by stopping the spread of mold, mildew, and dust mites in the home. These devices also help to reduce the ambient moisture in the air, protecting the home from rust and decay that can occur when walls, ceilings, and windows accumulate moisture.
There are also disadvantages to having a dehumidifier, one of which is a higher monthly electricity bill. They also require regular maintenance to ensure that they continue to function correctly. Maintenance includes emptying the collection bucket, cleaning the unit, and replacing the air filter to help purify the air.
Most dehumidifiers have a built-in humidistat to measure the ambient humidity, so while an oversize dehumidifier can cause the air in the home to dry out quickly, it should shut off when the humidity levels reach the preferred setting. However, without this automatic measurement and control, a dehumidifier can be too large for the space.
It can dry out the air rapidly to the point where it is too dry and you might need a humidifier to help reverse the effects. A whole-house dehumidifier is intended for this exact purpose. These products can have a range that exceeds 5, square feet, allowing them to condition the air throughout the home. No, do not leave the dehumidifier on all the time. Not only is it unnecessary, but excessively dry air can lead to breathing problems, like bronchitis, sinusitis, asthma, and nosebleeds.
The frequency with which you empty the dehumidifier depends on how often the device runs. Typically, a dehumidifier should be emptied twice a day, but some homes might only need to empty the bucket once every 2 days or so. Just be diligent about checking the dehumidifier when it is first set up to get a better understanding of how long it takes for the dehumidifier bucket to fill up.
Disclosure: BobVila. Why does a dehumidifier that had a capacity of 70 pints have a new capacity of 50 pints? The device is the same; what changed is the DOE sizing standard. The old standard took into account Energy Factor.
The new standard considers the Integrated Energy Factor that is more accurate in representing the capacity of a dehumidifier. Here is a quick graphic representation of how old vs. According to the old standard, you would need a pint dehumidifier. However, according to the new standard, you would need a pint dehumidifier.
You can get a small pint, a medium pint, or the strongest residential pint dehumidifier. This tells you the maximum amount of water in pints per day a dehumidifier can squeeze out of your air per day, according to the tests made by DOE. In short, the big pint dehumidifier can absorb almost 9 gallons of water out of the house or basement air per day.
You need to know how many sq ft of space you have and how humid those spaces are:. Note that some producers might be throwing around numbers like 3, sq ft or 4, sq ft. Always buy a big bigger dehumidifier. Dehumidifiers are the most useful for very moist basements.
Basements generally have an above-average humidity; this can spur spore and mold growth. In several decades, it can weaken the walls and put the whole structure of the house in danger. Installing a dehumidifier makes a whole lot of sense. Here are the basic metrics of the basement as an example :. If we check the dehumidifier sizing table above, we can see that the basement with these specs would need a or pint dehumidifier according to the old standard or a pint one according to the new standard.
What is most important, though, is the overall square feet capacity of the home in general. Placing a large capacity dehumidifier could do a good job for your two-bedroom home in general, especially when it possesses a good moisture removal rate, apart from the size of the room it is able to serve. The disadvantage of using this type though is that the impact of the dehumidifier reduces with distance; i. On the other hand, you can choose to go for a whole-house humidifier, but in most cases is your home capacity is less than sqft as in the case of host 2 bedroom homes today , it would be uneconomical to go for this option due to the larger energy consumption levels as well as the additional installation costs that come with purchasing it.
In conclusion, we would advise you go for a large-sized capacity unit that is on par with the total room size of your home the two rooms combined , and it should be mounted in an area where it can effectively circulate air around the home, instead of just being stationed in a room where it performs effectively, while the other parts of the home suffers as a result.
In a three bedroom type, your effective options are more limited in the sense that it is either you go for mobile capacity units that should be strategically placed around the rooms of the home, or you just deal with having to purchase a whole-house dehumidifier type.
For this reason, you can either choose to purchase several dehumidifiers, three precisely, in order for each to be placed in each room.
The picking of these units, of course, should be done with respect to the size of each room in question, hence a small capacity type when necessary, medium-size or the large type accordingly. On the other hand, in order to save the stress of monitoring and maintaining several dehumidifiers simultaneously, you can take the better option of purchasing a whole-house dehumidifier type.
As earlier said, this type of unit is able to cover grounds above sqft, and are installed with the HAVC system of the home. For this reason, it is able to cover all rooms of the home at the same time since it is connected to the ducts which are piped to each area of the home , and even accounts for extra spaces like the kitchen, bathroom, and toilet.
As far as there is a duct outlet in that space, then this unit would effectively do its job of dehumidifying. Choosing the right size of dehumidifier for your home is the most important process in the whole of picking a unit, which is why it is important you know the available types as well as their suitability.
You should also know the size of your home in general, as it would help you pick the right size of unit required. If you are considering up to a three-bedroom house whole dehumidification, then the whole house type is certainly for you, while for lesser sizes, you would need a corresponding small or large capacity type unit.
