Air filters, dehumidifiers and humidifiers

Technology can make the air in your home a lot healthier. But it can be a little confusing trying to decide which devices you and your family might need. Each one works differently to clear and change the air we breathe. Here’s a quick guide:

  • Air filters — pull mold, pollen, dust mites and other particulates out of household air. The best systems use HEPA filters that trap the particles.
  • Dehumidifiers — remove moisture from the air, curbing the growth of mold and dust mites. These work well in certain parts of the house where humidity collects.
  • Humidifiers — work well during winter months to counter the drying effects of home heating systems. The dry air can irritate your eyes, throat, lungs and skin. It can also harm your home.

The air in your home should range from 30 percent to 55 percent humidity. An inexpensive device called a humidistat can measure that humidity.

Here’s a detailed guide from University Health System’s Health Library that explains in detail how each device works and how it can help you and your family.
