In a heated space, which factor can significantly increase comfort and reduce indoor contaminants?

Controlling relative humidity is essential for enhancing comfort in a heated space and reducing indoor contaminants. When relative humidity is at an optimal level, typically between 30% to 50%, it helps maintain a balance that is comfortable for occupants. High humidity levels can make a space feel sticky and uncomfortable, while low humidity can cause dryness in the air.

Moreover, optimal humidity control discourages the growth of mold and mildew, which thrive in damp conditions. By preventing excess moisture in the air, it can also minimize the presence of allergens and other contaminants, like dust mites, that can exacerbate respiratory issues.

In environments where proper humidity control is maintained, the overall air quality improves, leading to a healthier indoor atmosphere. Therefore, prioritizing humidity control is a crucial factor for comfort and contamination reduction in heated spaces.
