Signs You Need a Dehumidifier
You may want to consider a dehumidifier if you have some obvious signs of high humidity in certain rooms or areas of your home, including:
- Water stains on the walls or ceilings of your home
- High humidity rooms with poor ventilation or no ventilation
- Frequent condensation on the windows in certain areas of your home
- Small black spots growing on the walls or in areas with high humidity, such as the bathtub or shower
- Must or mildew smells
You may also want to consider a dehumidifier if you live in an apartment building, since mold and mildew spores can travel through ventilation systems, and can build up in the walls between apartments. Even if you keep your living area clean, these allergens from other areas of the building can be harmful to your health.
Benefits of a Dehumidifier
- Dehumidifiers are effective units that come with many benefits for your space, and most importantly, yourself. They eliminate potentially dangerous variables that can affect your home, family and even your pets. Dehumidifiers prevent mold. Moist, damp air is the ideal environment for mold to flourish and a dehumidifier can remove the surplus moisture while preventing new mold from growing. If you or anybody in your home suffers from frequent asthma attacks or if you see mold growing in various places, then you should strongly consider getting a dehumidifier for your home.
- Dehumidifiers can improve the air quality of your home. The quality of air in your home is not only measured in the amount of toxins that you may or may not be breathing in, but also by the humidity levels of the air itself. While there’s no denying that an air purifier is the most effective way to cleanse the air of potentially harmful substances, a dehumidifier does indeed play an important role in improving your indoor air quality.
- Dehumidifiers can remove musty odors. A musty smell nearly always means that mildew and mold is present. These substances thrive on moisture, which starts to collect in areas like basements and garages when windows are not sealed correctly or there is seepage from ground water.
- Dehumidifiers help with allergy prevention. If you have significant trouble with your allergies, it may be due to your indoor air quality. Excess moisture in the air can cause airborne allergens such as dust mites and mold spores to grow and spread. Sometimes allergy sufferers are even more susceptible to indoor allergens than outdoors, making it even more important to make sure you’re breathing clean air.
- Dehumidifiers help you feel comfortable in your home. When moisture is present in your space, temperatures may feel warmer than they actually are. By removing moisture from the air, you will feel more comfortable without having to crank up your air conditioner. In fact, you could probably raise the temperature on your thermostat and make your home more energy-efficient, as a result. This is especially true throughout the warmest times of the year.
Types of Dehumidifiers
There are several different options when it comes to dehumidifiers, and the one you choose depends on the space in which you plan to use it, as well as the humidity levels. There are small capacity models for a single small room, large capacity models for larger areas such as a large room, basement, or an apartment, and there are whole-house models available as well if you live in a very humid climate, you suffer from significant allergies, or you have a large home.
Refrigerator Style Dehumidifiers
With a refrigerator style dehumidifier, moisture is removed by cooling the air. Air is brought into the unit through an intake and passed through a filter to remove particles of dust, dirt, and allergens that can be detrimental to health and bothersome to underlying illnesses. A fan pushes the air over a set of coils that cool the air, which makes the moisture in it condense and collect into a water collection tank. Then, the dry air which has been cooled is blown back into the ambient space by a fan.
Most of the dehumidifiers you see in home improvement stores are portable dehumidifiers. These are often inexpensive to purchase and lightweight, making them easy to transport from one room to another or even to a new location. They are often framed in plastic so that they don’t have excess weight or material, and while they can last a long time with proper care, they aren’t as sturdy as a whole house or an industrial unit.
Whole House Dehumidifiers
A whole house dehumidifier is a centralized unit that works much like an air conditioner, clearing the entire home space of excess humidity. These fixed units are more expensive and require installation by a professional, with requirements that they are connected to the duct work that is already installed for central air and heating purposes.
Heat Pump Dehumidifiers
With whole house units, one of the most common types of dehumidifiers is a heat pump unit. These use a fan to pull the moist air into the unit and across a cold coil, just like the refrigeration style models. The condensed water drops into a water collection tank or bucket and is then drained through a hose.
