How a Dehumidifier Can Help Control Allergies and Asthma

If you live in a humid climate or your home is prone to moisture problems, a dehumidifier may be a worthwhile investment. These units can help control allergies and asthma symptoms caused by dust mites, mold and mildew.

They can also prevent mold and dry rot, which is a serious structural problem that can weaken the structural supports of your home or shed.

Reduces Allergens

Many allergens thrive in humid environments, including dust mites, mold, and mildew. These allergens can trigger allergies, asthma, and other respiratory problems in some people. Using a dehumidifier can reduce the number of these allergens in your home and help you breathe easier.

A dehumidifier removes excess moisture from the air, causing relative humidity to stay within the Goldilocks range (between 30-45%). The EPA advises that humidity should be at a level that prevents condensation on windows and walls and doesn’t promote the growth of dust mites and other pests.

Dehumidifiers also eliminate musty odors, which are caused by mold and mildew. This is particularly helpful in basements and other damp areas. Mold spores can cause symptoms similar to pollen, so they should dehumidifier be eliminated from the air in your home, especially during allergy season.

A dehumidifier can even help reduce allergy-causing bacteria and some viruses that thrive in moist conditions. This is because these contaminants spread more rapidly when the environment is moist. While dehumidifiers can decrease the effects of certain allergens, they shouldn’t replace allergy medications. Many full-house dehumidifiers that connect to ventilation systems have filters that remove a lot of particles from the air. You can also find portable dehumidifiers with these filters.

Prevents Mold Growth

Mold can cause serious damage to your home if it takes hold. Its spores can settle on any surface that gets damp and will continue to grow as long as there is moisture. Mold spores can also trigger allergies and cause a variety of health problems, including sneezing, skin rashes, itchy eyes and more. Fortunately, the best strategy to control mold is to prevent it from growing in the first place.

This is a goal that dehumidifiers can help you achieve. These devices pull moisture from the air, decreasing humidity levels and eliminating the damp environment that mold thrives in.

Dehumidifiers work by drawing air in, filtering and cooling it to condense the moisture before releasing warmer, dryer air. They can be purchased in a wide range of sizes, with cheaper models offering less features and a smaller tank capacity while pricier options offer greater water-removal capability, energy efficiency and more features.

However, a dehumidifier can only do so much to control the growth of mold. Once it has taken hold in your home, you need to call a professional for mold remediation services and water damage repair. While it can be challenging to find the source of the mold, reducing the overall amount of moisture in your home is an effective approach. This includes limiting the number of wet spots in your home, especially those that can become a breeding ground for mold, such as leaks and condensation.

Reduces Water Damage

When you’re dealing with water damage due to a flood or leak, the first step should always be to remove as much of the standing water as possible and then dehumidify the area. This helps to prevent mold growth and keeps the area dry, which also reduces your risk of secondary problems such as structural damage and wood rot.

Even after professional water removal, however, moisture can linger in the air. It’s this excess humidity that leads to warping, rotting and other types of water damage to house structures. A dehumidifier can prevent this by sucking moisture out of the air, which dries up surfaces and eliminates the musty odor associated with water damage.

These devices work by sucking the air and running it over cold coils, which cause the moisture to condense. The condensation drips into either a collection tank or can be directed outside via a hose. They’re most effective in heated rooms and are more efficient if they have an auto-defrost feature, as the coils can often freeze during winter and stop them from working correctly.

A dehumidifier can remove up to 10 pints of water from the air in a day, depending on its size and settings. If you want to save energy, you can reuse the water that shows up in the dehumidifier’s bucket dehumidifier (called greywater). It’s not suitable for drinking, but it can be used for gardening and other purposes.

Reduces Energy Consumption

Keeping humidity in your home at just the right level is crucial for a comfortable environment. Too much humidity can cause irritated skin and respiratory problems, while too little humidity promotes mold and mildew growth and can lead to flaking paintwork. Dehumidifiers help you find the Goldilocks balance and keep your home a healthy place to live.

While dehumidifiers do consume electricity, modern units are typically much more energy-efficient than those of previous generations. Most units consume fewer kilowatt hours (kWh) than your refrigerator and use significantly less than a household water heater or air conditioner.

Energy costs for dehumidifiers can increase over time, however. This can be caused by clogged filters or by the unit needing to work harder to remove moisture from the air. By regularly cleaning or replacing the filter, you can prevent these issues and save money on your utility bills.

Other things you can do to reduce the cost of running your dehumidifier include ensuring that it is properly sized for the space it is intended to be used in. This will ensure that the unit is not overworking and that it is operating at peak efficiency. Additionally, it is helpful to seal any air entry points into your home so that humidity can not easily sneak inside and make the dehumidifier work harder.
