How should a nail salon maintain air quality?

Maintaining air quality in a nail salon is crucial for the health of both clients and technicians. One effective method to achieve this is by changing forced-air filters as required. Regular maintenance of these filters ensures that the air circulated in the salon is clean and free of harmful particles that can be released from nail products, dust, and other contaminants. When filters are clogged or dirty, they can allow these particles to remain in the air, potentially leading to respiratory issues or allergic reactions for both clients and employees.

Unlike the other options, which do not contribute positively to air quality, changing air filters directly addresses the issue of air cleanliness. Air fresheners might temporarily mask odors but do not improve air quality and can sometimes introduce their own chemicals into the air. Heavy curtains could block light but would not have any impact on improving ventilation or the overall air quality of the space. Finally, minimizing ventilation would trap fumes and harmful air particles inside, which is counterproductive to maintaining healthy air quality in a nail salon.
