What is the recommended indoor humidity level range for avoiding allergens and promoting comfort?

Maintaining an indoor humidity level in the range of 30-50% is widely recommended for promoting comfort and minimizing the presence of allergens. This level of humidity helps to inhibit the growth of mold and dust mites, both of which thrive in overly humid environments. At the same time, excessively low humidity can lead to discomfort, dryness in the skin, throat, and eyes, as well as increased susceptibility to respiratory ailments.

A humidity level below 30% can cause dry air issues, making it harder for the body to fend off pathogens and allergens, thus promoting health concerns such as asthma and allergies. Conversely, levels exceeding 50% can create an environment conducive to mold growth and allow dust mites to flourish, exacerbating allergy symptoms for sensitive individuals. Therefore, maintaining indoor humidity levels between 30-50% is crucial for both comfort and health, ensuring a balanced atmosphere that limits allergens and provides a pleasant living environment.
