What is a dehumidifier and what is it for?

A home's air quality significantly impacts the comfort and well-being of its residents. Dehumidifiers are appliances specifically designed to combat excess moisture in the air. By removing this moisture, they create a more comfortable and healthy indoor environment.

While some humidity is necessary for a healthy indoor environment, excessively low levels can also be problematic. Ideally, a comfortable and healthy humidity range falls between 30% and 50%. Many dehumidifier models come with built-in humidistats. These devices automatically shut off the dehumidifier upon reaching a predetermined humidity level, ensuring a comfortable and healthy indoor environment.

How do dehumidifiers work?

Dehumidifiers work through a process of condensation. They draw in air and pass it over a chilled coil system. This cooling causes water vapor in the air to condense, collecting in a built-in tank. The drier air is then released back into the room. Regularly emptying the tank is crucial for optimal performance.

Can a dehumidifier affect your health?

While dehumidifiers can effectively control mold and dust mite allergens, improper use can lead to certain health issues, including:

  • Very dry air can disrupt the natural moisture barrier of your skin, leading to dryness, itchiness, and even flaking. This can be particularly bothersome for people with existing skin conditions like eczema or psoriasis.

  • Dry air can irritate the delicate tissues in your eyes, causing redness, dryness, and a burning sensation. You might also experience increased sensitivity to light and blurred vision.

  • Dry air can dry out the mucous membranes in your throat, leading to a scratchy, itchy feeling. This can also make you more susceptible to coughs and aggravate existing respiratory conditions like allergies and asthma. It can also disrupt sleep by causing congestion, coughing, and dry mouth.

  • Dry air can thicken mucus in the respiratory passages, making it harder to clear your throat and leading to a more persistent cough.

  • Dry air can irritate the mucous membranes in your nose, making them more sensitive to airborne allergens like pollen and pet dander. This can lead to a worsening of allergy symptoms like sneezing, congestion, and runny nose.

  • Dry air can cause dust particles to become more easily airborne, leading to increased exposure to allergens that may have settled on surfaces. It can also increase static electricity, which can be annoying and attract dust particles, further aggravating allergies and respiratory issues.

Remember, the key is to maintain a healthy balance. Dehumidifiers can be very beneficial, but using them properly is crucial to avoid these potential downsides.

What are the benefits of a dehumidifier?

When used correctly, dehumidifiers offer a range of benefits for your home, creating a more comfortable and healthy environment. Here are some key advantages:

  • Dehumidification helps control the growth of mold and dust mites, common triggers for allergies and asthma. This can lead to fewer allergy symptoms like sneezing, congestion, and itchy eyes. Mold thrives in damp environments. Dehumidifiers help prevent mold growth by lowering humidity levels, protecting your home from structural damage and safeguarding your health from potential respiratory problems caused by mold exposure.

  • By controlling mold and dust mites, dehumidifiers can ease breathing difficulties for people with asthma and allergies. Additionally, drier air can help reduce the survival of some viruses and bacteria.

  • Futhermore, dehumidifiers prevent condensation on windows, walls, and other surfaces. This helps prevent the growth of mold and mildew, which can cause unpleasant odors and respiratory problems.

  • By removing moisture from the air, dehumidifiers make it feel cooler. This is especially helpful in hot, humid climates where sweating can be excessive. You'll experience a more breathable and refreshing atmosphere. Also, dehumidifiers can contribute to better sleep quality, especially for those who struggle with allergies or congestion in hot, humid weather.

Finally, it is important to note that excess moisture can damage furniture, books, electronics, and other valuables. Dehumidification can help protect these items from warping, peeling, and rusting. Not only that, but dehumidifiers can be very helpful in speeding up laundry drying, especially during humid weather.

How to use a dehumidifier

With so many options and settings, using a dehumidifier can seem daunting. By following these guidelines, you can effectively use a dehumidifier to create a more comfortable, healthy, and moisture-controlled environment in your home:

  • Dehumidifiers are sized based on the area they can effectively cover. Consider the square footage of the room where you'll be using it.

  • Position the dehumidifier on a level surface in a central location with at least a foot of clearance around it for optimal airflow. Avoid placing it near walls or furniture.

  • Dehumidifier tanks collect the removed moisture. Empty the tank frequently to prevent overflows and mold growth within the tank.

  • Refer to the manufacturer's instructions for proper cleaning and maintenance of your dehumidifier. This might involve cleaning air filters and wiping down the unit.

  • Keep doors and windows closed when using it. This helps the dehumidifier work more efficiently by preventing additional moisture from entering the space.

  • While using the dehumidifier, you can run exhaust fans in bathrooms or kitchens to remove additional moisture generated during activities like showering or cooking.

When to use a dehumidifier?

Aim to use your dehumidifier when humidity levels consistently exceed 50%. You can measure this with a hygrometer or some dehumidifier models even have built-in sensors. Condensation on windows, damp walls, or a musty odor are all signs of excess moisture that a dehumidifier can help address.

There's no need to run the dehumidifier constantly. Switch it off when the target humidity level is reached or when you're not in the room.
