What is the main goal of maintaining air quality in a library?

Maintaining air quality in a library primarily aims to enhance the learning and reading experiences of its patrons. Good air quality is crucial for creating a comfortable environment conducive to concentration and focus, which are essential for activities such as studying or reading. Proper ventilation, humidity control, and filtration of pollutants ensure that the air is clean and free from allergens, contributing to a healthier atmosphere. This directly impacts patrons' ability to engage with materials effectively, ultimately fostering a more productive and enjoyable experience in the library setting.

While reducing operational costs, complying with building codes, and facilitating circulation may be important aspects of library management, they do not specifically address the core benefit that air quality improvements offer to the users of the space. The enhancement of learning and reading takes precedence, making it the main goal in maintaining indoor air quality in libraries.
