What size dehumidifier do you need? The proper dehumidifier size depends on the size of the space you need it to dehumidify and on how damp that space is. It’s important to figure out the correct size dehumidifier you need because if you purchase a dehumidifier that’s too small for your needs, you will not get the benefits you’re looking for. On the other, you can save money on both the purchase price of a dehumidifier and on your monthly energy bill by not purchasing
a bigger dehumidifier than you really need. Show
How Is Dehumidifier Size Measured?When people talk about the size of a dehumidifier, they are usually referring to what’s technically known as capacity. The capacity of a dehumidifier is how many pints of water it can remove from the air in one day. Generally speaking, higher capacity dehumidifiers are larger in size than smaller capacity dehumidifiers. For example, the 30 pint dehumidifier from Frigidaire is just over 19 inches high and 14 inches wide, while the 70 pint dehumidifier from Frigidaire is 25 inches high and almost 18 inches wide. Wondering what size dehumidifier you can purchase? Different brands offer different sizes. For instance, Frigidaire offers 30 pint dehumidifiers, 50 pint dehumidifiers and 70 pint dehumidifiers. General Electric offers 30 pint, 40 pint, 50 pint and 65 pint dehumidifiers. You can also purchase a whole-house dehumidifier if you need to control moisture throughout the house instead of simply one room. So What Size Dehumidifier Do You Need?Selecting the right dehumidifier size is important if you want to remove excess moisture from your home, improve the air quality in your home and prevent the growth of mold in the home. The Association of Home Appliance Manufacturers (AHAM) has issued some basic guidelines to help you select the proper dehumidifier size for your needs. A 30-pint dehumidifier should be adequate for most spaces up to 1500 square feet, regardless of how damp the area is, according to the Association of Home Appliance Manufacturers. A 30-pint dehumidifier should also be sufficient for a moderately damp space (feels damp and smells musty when it’s humid outside) up to 2000 square feet. However, you’ll need a 40 or 50-pint dehumidifier for a 2000 square foot space that feels damp and smells musty all the time, or a 2000 square foot space where you can see moisture on the walls or floor, or a 2000 square foot space where you’ve experienced a problem with mold. You may need a 60 or 70-pint dehumidifier for larger areas, particularly if the space is very damp. Measure the area that you want to dehumidify to make sure you know what dehumidifier size you need. To calculate the square footage, simply multiply the width of the room and the length of the room. While people may be most likely to find dampness and a musty smell in their basements, they may find mold growing in other areas of the home such as bathrooms. Humidity can be a problem in any room, even if it’s more common in some rooms than others. If humidity is a problem in a significant portion of your home, a whole-house dehumidifier may be the right choice for you. A whole-house dehumidifier is installed as part of your home heating and cooling system and it keeps the level of humidity constant throughout the house. You can select the degree of humidity you want; in order to prevent the growth of mold, it is recommended that you keep the humidity below 50 percent. Buying The Right DehumidifierAfter evaluating the top brands of dehumidifiers based on performance, reliability, durability and price, we have found that the best overall dehumidifiers are made by Frigidaire.

Home > Dehumidifiers > Dehumidifiers FAQs > What Size Dehumidifier Do I Need (A Step by Step Guide) | Basement, Bedroom, House, Apartment, and Garage The size of your dehumidifier depends on the size of the indoor space and humidity levels are in that area. Humidity is a factor that will determine what you need to do with excess water collected from the air. Smaller rooms might only need 30 pints, but larger spaces may require 70 or more! This article breaks down every step for choosing the right size dehumidifier for your needs. What Size Dehumidifier Do I Need?
Example: A room with square footage of 500 sq ft, a relative humidity of 80% and average temperature of 70°F - will require a 50- or 60-pint dehumidifier. Step 1. Check the Room's Humidity LevelA room with high humidity levels, wet surfaces or a musty smell might need a dehumidifier. A dehumidifier will work harder in a really wet space than one that is just damp. You can use a humidity meter to measure the moisture of the room, or you can assess it based on these general criteria:
Note: One way to check the humidity level in your house is to buy a hygrometer at the drugstore. Place it in the room that you want to test and follow the instructions on how to use it. The hygrometer will show you what percentage of humidity there is.
You should take steps to eliminate or reduce the source of excess water in a room if you detect it. Step 2. Measure Average Room TemperatureTo measure the temperature in a room, you need to use a thermometer. To calculate the temperature in a room, you can also download an app and use your phone's sensors. Step 3. Measure the Size of the RoomYou will need to measure the size of the room to work out what size dehumidifier you will need for that room.
Example Room 1: Square Feet SpaceIf you have a room that is 15 ft long and 20 ft wide the room size will be 300 square feet.
Room Space = 300 square feet Example Room 2: Square Feet SpaceIf you have a room that is 25 ft long and 30 ft wide the room size will be 300 square feet.
Room Space = 750 square feet Step 4. Calculating What Size Dehumidifier Do I Need?Two Dehumidifier Sizing Standards: Used By the US Department Of EnergyWhen you measure your home, there are two (US DOE)standards for testing a dehumidifier.
A dehumidifier can be of different sizes. It used to be 70 pints and now it is 50 pints. There was a change in the DOE sizing standard. In 2012, the standard was based on Energy factors. The 2019 standard is based on the Integrated Energy Factor which is a more accurate way of measuring how much dehumidifier it can do. It also tests the dehumidifiers at a lower temperature (65°F) that the older standard's testing temperature (80°F). That’s why both the dehumidifier size chart and dehumidifier size calculator include both old and new capacity. After 2022, only the new standard will be used. AHAM Dehumidifier Sizing Table
Dehumidifiers can remove water from the air. The difference is how much water it can remove per day. You can get a small 30-pint, medium 50-pint, or strongest 70-pint dehumidifier. A pint is a unit of measurement. It's not as big as a gallon, but it still amounts to 1/8 of that. A 70-pint dehumidifier can take 9 gallons of water out of your house or basement each day. How big a dehumidifier should you buy? This is a table of the Association of Home Appliance Manufacturers. There are a few things you will need to know about your home before you can read the table. You will need to know how many sq ft it has, and how humid those spaces are. If you have a 500 sq ft basement and it has medium humidity (70%-80%), you would need a 50-pint dehumidifier to lower the moisture levels. That's a ballpark figure. Note that some people might say 3,000 sq ft or 4,500 sq ft but you should not listen to those numbers. In some basements, there is too much moisture, high relative humidity, and high average temperature. That can make the basement have high moisture levels, where mold and spores grow. It can also make the house's walls weaker over time and put the whole house at risk. Check or guide on the best dehumidifier for basement.
If we look at the table, we can see that the basement with these specifications would need a 50- or 60-pint dehumidifier (according to the old standard) or a 25-30 pint one (according to the new standard). When you have a choice between two sizes of dehumidifier, always pick the bigger size. It is better to have a more powerful dehumidifier than one that does not work well. The AHAM sizing chart does not consider the average temperature. If you have a cold basement, you are going to need to add 10 pints for every cubic feet. What Size Dehumidifier Do I Need for a Whole House?These are the sizes of a small house:
We can deduce that a house of this size would need a 70-pint dehumidifier (old standard) or 50-pint dehumidifier (new standard). For larger spaces, you might want to consider the high capacity commercial dehumidifiers. Large Spaces More Than 2,500 Square FeetIf you often deal with excess moisture and humidity and see things like mold or experience musty odors, you need a whole-house dehumidifier. This is ducted to your HVAC system. It gets rid of the moisture before it can come into your home. Whole-house dehumidifiers cover a lot of space (3000 sq. ft. or more). The first price is higher, but it will cost less in the long run. They also help your AC work better because when the air is dry, it cools better. Small Spaces Between 100 and 250 Square FeetIn small rooms, it is hard to fit a large 70-pint dehumidifier. That's why we recommend the mini one. Mini dehumidifers work quietly and they can cover 100-300 square feet. They work when the room is the right size. Mini dehumidifiers are small and easy to use. They can fit in bedrooms, children's rooms, or nurseries. They hold a few pints of water. Most mini dehumidifiers will also turn off when the tank is full. Homeowners like mini dehumidifiers in their bedroom. These are small and quiet. They don't have a noisy compressor. Instead they use thermoelectricity. Cool EnvironmentsIf you live in a cold environment, it is best to not buy a dehumidifier because they won't work. The coils might freeze and then the whole thing doesn't work anymore. Note: Refrigerant dehumidifiers cannot work in cooler temperatures. When the temperature is below 60 degrees Fahrenheit, there is a risk of ice forming on the coils. The dehumidifier will waste energy and if left, it can get broken from inside. Desiccant dehumidifiers are a way to solve the humidity problem. They have a rotor that is filled with sheets that will take out moisture in the air. The air is pulled through with a fan, and then it goes past the sheet with desiccant material on it. Furthermore, desiccant dehumidifiers are quieter than other ones. They're also more energy-efficient and effective at drying already dry air. Hot EnvironmentsIf you live in the south, the humidity might be high. You will want to get a dehumidifier. The best kind of dehumidifier for this is one that takes refrigerant (because it can remove more moisture and work in higher temperatures). Refrigerant dehumidifiers pull the air in through a fan and then cool it on a set of coils. The refrigerant liquid is pumped through the system, converting between gas and liquid form as it cools and heats. https://youtu.be/Qjt8rgCtT3o There are other things to think about.There are many things that can make the humidity in a home higher than normal. These include:
Frequently Asked QuestionsIs It Possible to Use a 70-Pint Dehumidifier When Only 30 Pints Are Required?It is possible to use a 70 pint dehumidifier. It will not hurt you or the room, but it may be loud in small areas. If you have a large dehumidifier, it will make the room drier faster and save energy. Is it better to get a bigger dehumidifier?Theoretically, yes. But here's why: A larger dehumidifier will work more quickly at drawing moisture out of the air, so you can turn it off sooner. This means that it will save more energy. On the other hand, larger dehumidifiers are usually very loud. If you have a small bedroom, it might be too loud to run a 70-pint unit while you're there.
