What does a dehumidifier do? Many people purchase a dehumidifier for allergies or asthma relief, to make the humidity level of a room more comfortable or to help prevent mold in areas that are commonly moist such as a basement. However, dehumidifiers offer a long list of benefits and perform various functions. In fact, most homes, apartments and offices should have a dehumidifier available for use throughout the year.
What Does A Dehumidifier Do
The basic operation of a dehumidifier is straightforward. A unit sucks air into an inner chamber, which then passes over very cold coils. When the warm air passes over the cold coils, the moisture is drawn out of the air and drips into a storage bucket or tank inside the unit. The air then passes through the system and out into the room once again. Additionally, Dehumidifiers use various filters, which remove allergens and dust from the air.
Dehumidifier Power Consumption
Before purchasing a unit, you can find information about dehumidifier energy use on its label, in most cases. Energy consumption for these appliances is measured in kilowatt-hours or kWh. The Energy Factor of a unit will tell you how efficient it is and measures the liters of moisture removed per kWh. Units that meet the highest industry standards in performing the dehumidification of air efficiently are certified by Energy Star.
Benefits of a Dehumidifier
Too much moisture in the air can make a room uncomfortable and seem warmer than it actually is. A dehumidifier will keep the humidity level of a room consistent and at your preferred setting, providing a more comfortable environment. Additionally, they also provide health benefits and help prevent damage to buildings of all types. By removing moisture and filtering the air, a dehumidifier removes allergens from the surrounding environment and helps prevent mold from growing.
Allergens and dust trigger allergies and create an unhealthy environment for those who suffer from asthma. Areas that continually remain moist promote the growth of mold and other bacteria, which can cause expensive damage to a home or office, as well present health risks. Controlling the level of moisture in the air can also help keep certain types of food such as bread and cereal fresh for longer periods. If any of these issues are a concern for you, then you should consider a dehumidifier for mold prevention or a unit that will help with allergies.
Types of Dehumidifiers
A low-temperature dehumidifier means a unit can efficiently remove moisture from the air in what is considered low-temperature environments for dehumidifiers. Because most units use systems reliant on temperature variations to perform moisture removal, it is important to choose a model that is designed to perform in these conditions, if required. A good example of a unit designed for this is the DeLonghi DD70PE, which comes with an anti-frost feature and can operate in temperatures down to 41 degrees.
Portability can be a major concern for owners, as many need to move units to different parts of their home depending on circumstances. Often units will come with built-in handles and caster wheels, which help move a unit without too much effort. However, you should also pay attention to the overall size and weight. This EdgeStar portable dehumidifier is an excellent choice for smaller rooms and allows for easy portability.
Eva-Dry offers a line of mini dehumidifiers that are a good choice for boats, closets and small areas where moisture can be a problem. Mini units are normally designed for spaces of 400 square feet and smaller, where a larger unit just is not practical. There are many other makes and models available in the mini category depending on your needs.
Non-electric dehumidifiers typically mean they do not need to be plugged in or require a source of electricity during operation. With no wires or cords to contend with these units offer a convenient and hassle-free way to keep moisture levels under control. Most units will require recharging every 2-4 weeks depending on the model you choose. There are several different models available depending on the space you are working with, but this model from Lagute might be a good choice if you need to remove moisture from a small room or closet.
Self-draining dehumidifiers offer wonderful convenience allowing owners to avoid constantly emptying storage buckets when they become full. These units come with a built-in pump that can move water up to 15-20 feet in some cases. This means you can use a hose to direct the water out a window or into a drain of some sort. This is one of the most convenient features offered with dehumidifiers if you can arrange the unit in a way that allows you take advantage of it. For larger spaces, this 70-liter unit from Friedrich comes with a pump directly from the factory.
