What size dehumidifier do I need for 1500 square feet?

Last Updated: 30th March, 2020

A 30-pint dehumidifier is suitable for basements and crawl spaces of up to 1,500 square feet. 40 to 50-pint dehumidifiers tend to fall somewhere in the middle of the range as far as capacity is concerned. Again, they are suitable for spaces up to 2,000 square feet in size much like the 30-pint units.

Also, what size dehumidifier do I need for 1000 square feet?

Use a 30-pint dehumidifier (or a unit between 24- and 39-pint capacity) in the following conditions: Damp rooms of 500-1,500 square feet. Very damp rooms of 500-1,000 square feet. Wet and extremely wet rooms of 500 square feet.

One may also ask, is it better to get a bigger dehumidifier? Firstly, even if the dehumidifier is more expensive it will pay off later because the higher capacity dehumidifier will work fewer hours to collect all moisture and without using the maximum capacity. Secondly, higher capacity dehumidifiers usually have bigger water containers.

Additionally, what size dehumidifier do I need for 800 square feet?

Many large units handle up to 2,500 square feet, while smaller units handle spaces up to 1,000 square feet. If your basement is 800 square feet, and moderately damp, a small unit that removes between 50 and 70 pints is ideal.

Does opening windows reduce damp?

When the temperature outside is low, it'll cool the window glass. Then, when the warm air inside the house comes into contact with the glass, it will react to it and fog it up. But even though condensation is simple — damp is anything but. Damp can't actually be chased away by simply opening the windows.

Where should you place a dehumidifier?

To use your dehumidifier, put it in the most humid room in your house, like the bathroom, laundry room, or basement. Try to place your dehumidifier as close to the center of the room as you can, or at least 6-12 inches away from walls and furniture, since it will work better when there's good air flow around it.

Will a dehumidifier in the basement help the whole house?

The problem is that a dehumidifier ONLY addresses moisture that is evaporated into the basement. But the bulk of the moisture is coming from your basement walls and floor. It is ground water seeping through the concrete, which is very porous, and a dehumidifier alone won't help it.

Can one dehumidifier do a whole house?

Whether you'll want to go with a whole-house dehumidifier or a portable one depends on how much of your home has excessive humidity levels. Portable dehumidifiers can work for a small area, like a basement, but to decrease humidity levels throughout your home, you'll want to go with a whole-house dehumidifier.

Do dehumidifiers prevent mold?

Dehumidifiers help reduce odors that can accompany mold and mildew in your home—getting rid of that “musty” or “rotting” smell. Running a dehumidifier helps reduce dust in your home, so you won't have to clean as often. A dehumidifier also lowers energy costs because it helps your air conditioner run more efficiently.

Do I need a dehumidifier with a pump?

For dehumidifiers that don't have a pump, they sometimes come with a drain hose that uses gravity to help drain the water. It's important to note that because the water removal relies on gravity it can only flow downwards, not vertically, like a dehumidifier with a built in pump.

What is the difference between a 50 pint and 70 pint dehumidifier?

In a given area a 50 pint dehumidifier will run for more hours each day in order to maintain a relative humidity of, say 50%. As the noise difference between the 50 pint and the 70 pint is imperceptible that means that the 50 pint will create more noise interference during a day than a 70 pint unit.

Is a 30 pint dehumidifier big enough for basement?

30 Pint Dehumidifier
Any area up to 2,000 square feet, with a moderate level of humidity, will be suited to a model that collects 30 pints of water per day. In a basement, however, you might want to go for a slightly larger dehumidifier as they typically tend to be damper even though the floor space might be the same.

How do you size a humidifier for your house?

The standard output measurement for furnace humidifiers is the number of gallons of water absorbed into the air in a 24 hour period. A traditional counter top humidifier designed to provide adequate humidity for a standard sized room will usually hold about one or two gallons of water.

How do you measure humidity?

A device to measure relative humidity is called a hygrometer. The simplest hygrometer - a sling psychrometer - consists of two thermometers mounted together with a handle attached on a chain. One thermometer is ordinary. The other has a cloth wick over its bulb and is called a wet-bulb thermometer.

Can a dehumidifier be too large?

Your standard dehumidifier will remove the moisture from the air in your home, but the size you need depends upon the size of the space in question. A model that's too small for your space may hardly make a dent in the moist air, while one that's too large may make the air excessively dry.

Will a dehumidifier work for multiple rooms?

Can a dehumidifier work in more than one room at a time? A dehumidifier is going to be most effective in the one room it is in. If you have multiple rooms connected by open doorways with a very open floor plan, then the dehumidifier is more likely to be able to work in those other rooms as well.
