Air conditioners don't just keep you cool — they help you breathe more easily during the summer. You'll wake up feeling refreshed in the morning, and you'll experience fewer respiratory issues. Even though flowers are blooming and trees are growing, you can take a deep breath without sneezing thanks to your air conditioner.
Respiratory issues are most often caused by chemicals such as paint, gasoline, and cleaning products and particulates such as dust, mold, and pollen. Thankfully, you probably won't need to live with chemical odors on a regular basis, and your ductless air conditioning system excels at removing solid particulates from the air.
Every air conditioner uses an air filter to clean the air as it passes through the blower unit. Window air conditioners use rudimentary filters that only catch large particulates like pet fur, but central and ductless systems both use improved filters that catch almost everything else.
Because they don't use ducts, ductless systems clean the air better than central air conditioners. Return and supply ducts can leak air, collect dust, and lower the system's overall efficiency. Ductless systems suck in air and blow it back out at the same location, and you'll never have to pay for a duct cleaning service.
You can further improve your indoor air quality by controlling the amount of humidity present in your home. Most people find a relative humidity of 50 percent to be comfortable, but the outside humidity often climbs above 70 percent during the summer. A ductless air conditioner removes humidity by chilling the air. Cold air holds less moisture than warm air, so water condenses on the ductless AC's coils and drips outside through a drainage pipe.
Air filtration and humidity controls only work if your home is sealed up tight. Unlike window air conditioners, ductless systems don't allow air to pass through your walls, and you'll be able to use all of your windows.
