![]() Because there is no physical filter, UV HVAC filters are neither washable or disposable. ![]() UV air filters are often used to supplement another type of air filtration system. Instead, UV filters use the disinfecting power of ultraviolet light to eliminate airborne particles, including pathogens and microorganisms like viruses, bacteria and mold. UV HVAC air filters do not use fiberglass, cotton, plastic or any other type of fiber to filter particles out of the air. HEPA filters are available in washable or disposable options. Not all HVAC systems can handle high-density HEPA filters, and they can be expensive. HEPA filters are commonly used in settings such as medical clinics, hospitals and laboratories, where extremely pure air is especially important. HEPA is an official efficiency designation endorsed by the Department of Energy. In fact, an HVAC filter cannot be considered a HEPA filter unless it consistently filters out at least 99.97 percent of all particles 0.3 microns or larger. HEPA filters are highly effective at removing particles from the air. HEPA stands for High Efficiency Particulate Air. Disposable pleated air filters cannot be washed and reused like washable air filters. These layers are pleated, which provides more surface area to catch particles. Pleated filters are made from dense layers of cotton or plastic fibers. Disposable Pleated HVAC Air Filtersĭisposable pleated HVAC air filters are single-use air filters, like their fiberglass counterparts, but they are constructed differently. Because they can be reused, washable air filters are more eco-friendly than disposable fiberglass filters, but they are also more expensive. Washable air filters are typically made out of woven polypropylene media and are electrostatically charged in order to capture more particles. Washable or reusable filters can be rinsed with water or vacuumed to remove any particle buildup. In general, disposable fiberglass HVAC filters are the most common and most affordable type of furnace filter, but they must be regularly replaced in order to maintain HVAC efficiency and air quality. The fiberglass mesh catches debris as the air passes through. Traditional flat-panel filters feature fiberglass mesh stretched over a cardboard framework.
