What Does a Whole-Home Humidifier Do?

Why whole-home humidifiers are one of the most valuable comfort additions for Michigan homes heated by forced-air furnaces.

During Michigan winters, outdoor air holds very little moisture. When that cold air is pulled into your home and heated to 70°F by your furnace, the relative humidity inside can drop below 15%—drier than the Sahara Desert.

The Impact of Dry Winter Air - **Physical Discomfort:** Dry air dries out skin, chaps lips, and irritates nasal passages, making residents more vulnerable to winter respiratory bugs. - **Static Electricity:** Frequent static shocks when touching doorknobs or blankets. - **Wood Damage:** Hardwood flooring, wood trim, musical instruments, and antique furniture shrink, warp, or crack when moisture is depleted from indoor air. - **Higher Heating Costs:** Moist air feels warmer than dry air. When your home has proper humidity (between 35% and 45%), 68°F feels as comfortable as 71°F in dry conditions, allowing you to keep your thermostat set lower.

How a Whole-Home Humidifier Works Unlike small portable tabletop humidifiers that only treat a single bedroom and require constant refilling, a whole-home humidifier installs directly on your furnace supply or return plenum. It connects to your home's water supply and delivers moisture throughout your entire living space via your existing ductwork.
