Whole-Home Dehumidifiers

High humidity is a breeding ground for indoor air pollutants that can cause harm to your Healthy Home. Allergy and asthma symptoms like stuffy nose, itchy eyes, sneezing, and difficulty breathing are common with high humidity.

Airborne viruses like COVID-19 and influenza also thrive in excess moisture. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends keeping your home's humidity between the Healthy Humidity range of 4060 percent. With an AprilAire dehumidifier, you can reduce the number of viable viruses in the air to less than 1% in 2 days when the dehumidifier is set to 50%.*

Whole-Home Dehumidifiers Help with Reducing:

  • Dust Mites
  • Mold Spores
  • Mildew
  • Odors
  • Energy Costs
  • House Damage
  • Airborne Viruses

Not only can high humidity cause health complications due to the increase in indoor air pollutants like dust mites and mold spores, it can also cost you money on energy.

Your air conditioner is able to pull some moisture out of the air, which lends itself to cooling the air you and your family enjoy during hot, humid weather. However, when you incorporate a dehumidifier into the mix, you’re relieving those duties from your air conditioner, allowing it to focus more on cooling the air.

While running two units simultaneously may seem like it should drive energy costs up, what happens is that those two units actually run more efficiently because they’re working in sync with each other. And not just that, drier air actually feels cooler than hot, humid air, meaning you can turn the temperature on your thermostat up a few degrees and save energy simply by not having to run your air conditioner as often.

Utilizing a dehumidifier can also help protect your house itself. High humidity can cause wood to warp or rot, paint to peel, and insects to find comfortable new homes thanks to excess moisture.

People can’t easily distinguish between 40 to 60 percent humidity, but for a dust mite that’s life and death.”
