Which of the following is a benefit of using a properly sized 4" pleated media filter compared to a 1" fiberglass air filter?

Using a properly sized 4" pleated media filter offers significant benefits, particularly in enhancing indoor air quality. Unlike 1" fiberglass air filters, a 4" pleated media filter has a larger surface area and can trap smaller particles more effectively, including dust, pollen, pet dander, and mold spores. This superior filtration can significantly reduce allergens and contaminants circulating in the air, leading to a healthier indoor environment.

Furthermore, pleated media filters generally have a higher MERV (Minimum Efficiency Reporting Value) rating compared to fiberglass filters, meaning they are designed to capture finer particles. Improved indoor air quality is particularly important for individuals with allergies, asthma, or other respiratory conditions, as cleaner air can alleviate symptoms and promote overall well-being.

While other options mention aspects like reusability and odor removal, the primary and most impactful benefit of transitioning from a fiberglass filter to a pleated media filter is the enhancement of indoor air quality, making it a critical consideration for air conditioning system maintenance and indoor health.
