To lower humidity in a house, the most effective methods include using a dehumidifier, running air conditioning, improving ventilation, and addressing moisture sources. Dehumidifiers pull moisture from the air, while air conditioners cool and simultaneously reduce humidity. Ventilate high-moisture areas such as bathrooms and kitchens with exhaust fans or open windows when outdoor humidity is lower. Additionally, sealing crawl spaces, ensuring dryer vents exhaust outside, and reducing moisture-causing activities like long showers or cooking can help control indoor humidity. Some houseplants like Boston ferns and peace lilies also absorb moisture, aiding humidity control naturally.
Key practical steps to lower humidity:
- Use a dehumidifier for high humidity rooms or consider whole-house systems.
- Run your air conditioner to cool air and remove moisture.
- Use exhaust fans in kitchens and bathrooms during and after moisture-producing activities.
- Improve home ventilation by opening windows strategically when outdoor humidity is low.
- Seal crawl spaces with vapor barriers and keep dryer vents clear and outside.
- Limit activities that increase moisture, such as drying clothes indoors or boiling water.
- Use moisture-absorbing substances like rock salt or baking soda in small areas.
- Consider humidity-absorbing houseplants as a natural method.
These approaches combined help maintain indoor humidity at comfortable and healthy levels, ideally between 30-50%.
