What Are Whole-House Dehumidifiers
Whole-house dehumidifiers are upscale systems that keep humidity in check and under control throughout an entire home. These systems integrate with your HVAC network for comprehensive moisture control. Unlike portable dehumidifiers, they provide uniform moisture control throughout the house. They address the source of too much humidity. Not only does this action improve indoor air quality, it helps create a healthier, more comfortable living environment.
These whole-house units work by removing extra humidity from the air. The process starts when air travels through the system. Inside, evaporator coils chill the air, making water vapor condense into liquid. The collected moisture is then drained away through continuous drainage systems, allowing for nonstop moisture management.
This effective moisture removal helps ensure your home stays dry and comfortable. That reduces the likelihood of mold, mildew, and musty smells commonly associated with excessive humidity.
It’s important to keep humidity levels between 30%-50% for your comfort and health. This protection helps ensure your wood furniture, flooring and other household materials aren’t damaged by excess moisture.
