Dehumidifiers come in a variety of sizes, and which unit is right for you depends on a couple of factors. Most importantly, you should be aware of the square footage of the room that you want to dehumidify and the approximate humidity level of the room. If you begin your buying process knowing these things, you’ll be less likely to purchase a unit that is either too powerful or not powerful enough for the space you are looking to dehumidify. The chart below can help you estimate the unit’s moisture capacity: What is the “capacity” of a dehumidifier? Each dehumidifier unit is categorized by the total amount of moisture that they will absorb from the surrounding atmosphere in a one full day, and is usually measured in pints. A forty pint dehumidifier would be rated to absorb forty pints of humidity in a single day. However, though the unit may be absorbing forty pints of humidity in one day, sometimes the unit will only be equipped with a twenty pint tank. This means you should empty the moisture bin yourself ensure your unit is working at its best. If you don’t want to do that, you can always get a humidifier that includes a direct drain function. This allows the unit to constantly drain the collected moisture into a nearby drain so you don’t need to empty the tank yourself. Which model would be the cheapest to operate? Units with “Energy Star” ratings will help you save money on operating costs. This rating is an internationally recognized category of electronic units that are energy efficient. The dehumidifiers that are Energy Star rated are marked on our website. It is also important that you pick a dehumidifying unit that is not too big or small for the area that you are dehumidifying, and that the model accurately matches the level of humidity present in the area. This can cause your unit to run more frequently, which spends more energy than you should be using. As long as you use your Energy Star unit intelligently, your operating costs should not be too high. Would a dehumidifying unit heat up the room that it’s in? A dehumidifier will create heat in its immediate area. The heat level will differ depending on unit size of the dehumidifier and the square footage of the room. If the room is naturally warm, then the dehumidifier will be much more efficient at pulling the moisture out of the air. If the room is exceptionally cold, then the unit might not work at all. Dehumidifiers also tend to raise the room temperature about 5 degrees. These are important factors to keep in mind when choosing the right unit for your office or house. What type of dehumidifier do I need for a larger space? While dehumidifiers do come in large sizes targeted at bigger rooms, it is more important that the room have a good airflow. Good airflow encourages a unit to dehumidify throughout multiple rooms. Stagnant air is less effective at doing this. If your home has naturally poor airflow between rooms and yet you want to dehumidify several rooms, it might suit your needs to invest in a portable fan or two. How loud will my dehumidifier be? For people who live in an apartment complex, share walls with another unit, or are just very particular about keeping their home quiet, having a silent dehumidifier is an important factor. Typically, dehumidifiers are not as loud as an air conditioning unit. That being said, a dehumidifier does make a little bit of noise when in use. If it bothers you too much, you might consider locating your unit in an area of your home or office where you can muffle the noise a bit. As a rule, the average home dehumidifier is no louder than a normal human conversation.
