What is the main drawback of using fiberglass filters?

The main drawback of using fiberglass filters is their poor filtration efficiency. Fiberglass filters are typically designed to capture larger particles, and while they may provide some level of air filtration, they do not effectively trap smaller particles, such as dust mites, pollen, or smoke. This limitation means that they allow many airborne contaminants to pass through, which can negatively impact indoor air quality.

In contrast to filters specifically engineered for higher efficiency, such as HEPA filters or pleated filters, fiberglass filters fall short in their ability to provide comprehensive air cleaning. This aspect is particularly important in environments where air quality is crucial, such as in residential spaces or healthcare facilities. As a result, while they might have some benefits, the lack of effective filtration is a significant drawback that needs to be considered when selecting an air filter for specific applications.
