It’s hot out there. And depending on where “there” is, it’s humid too. And while it gives that dewy glow, too much indoor humidity can lead to mold, musty smells, dust mites, and an overall uncomfortable living environment. While dehumidifiers are a no-brainer, there are several natural ways to dehumidify your home—no plug-in appliances required.
Ventilation Is Key Poor air circulation is a major cause of excess indoor humidity. Start by:
- Opening windows: Even just 15–20 minutes a day can help improve airflow and reduce moisture.
- Using exhaust fans: Make a habit of running fans in the kitchen and bathroom during and after use.
- Keeping interior doors open: This encourages cross-ventilation and prevents pockets of trapped humidity.
Absorb Moisture with Natural Materials Some household items naturally pull moisture from the air:
- Rock salt: Place bowls of rock salt in damp areas like closets or basements. It draws in moisture and requires no energy.
- Charcoal briquettes: Like rock salt, they absorb humidity and can be placed discreetly around the home.
- Baking soda: Great for small spaces—just place an open box or bowl in a closet or cabinet.
Houseplants That Fight Humidity Certain plants actually absorb moisture through their leaves and can help regulate indoor humidity:
- Peace lily
- English ivy
- Boston fern
- Tillandsia (air plants)
Just don’t overwater them—they’re here to help with the damp, not add to it!
Dry Clothes Outdoors (When You Can)Hanging wet laundry inside adds a surprising amount of moisture to the air. If possible:
- Hang clothes outside or use a drying rack on a balcony or patio.
- If drying indoors is a must, crack a window and close the door to the room.
Fix Leaks and Seal Trouble SpotsUndetected leaks and poor seals around windows or pipes can make your humidity problem worse.
- Inspect plumbing for leaks.
- Seal window and door gaps with weatherstripping.
- Check roofs and basements for signs of moisture intrusion.
Use Natural Desiccants in Problem Areas Clay-based moisture absorbers like diatomaceous earth, silica gel, or calcium chloride (available in bulk) can be placed in containers in humid zones. These are especially useful in:
- Closets
- Bathrooms
- Under sinks
- Basements
Let the Sun In Sunlight not only warms the house but also helps evaporate excess moisture from surfaces and fabrics.
- Open blinds or curtains during the day.
- Rearrange furniture to avoid blocking light from windows.
