Types Of HVAC Filters
HVAC systems generally include filters that improve air quality by trapping dust, pollen, and other particles. HVAC filters come in a variety of styles, including fiberglass, pleated, HEPA, and electrostatic, with different filtration performance. Filters must be changed on a regular basis to ensure optimal system functioning.
One of the most crucial components of HVAC system maintenance is replacing or cleaning the filter on a regular basis. HVAC filters are vital for catching airborne particles that might degrade the air quality in your house or business. There are several varieties of HVAC filters on the market, each with its own unique function. In this part, we’ll look at the three most prevalent types of HVAC filters: fiberglass, pleated, and HEPA filters.
Fiberglass Filters
Fiberglass filters are the most basic form of HVAC filter and frequently the cheapest alternative. These filters are comprised of laminated fiberglass fibers that trap bigger airborne particles like dust and lint and keep them from flowing throughout the system. However, they are ineffective in capturing smaller particles such as pollen, mold spores, and pet dander. Fiberglass filters must be replaced every 30 days to keep them functional.
Pleated Filters
Pleated filters offer greater efficiency than fiberglass filters. These filters, constructed of polyester or cotton folds, collect a broader spectrum of airborne particles, including tiny ones such as mold spores and pet dander. Pleated filters offer a wider surface area than fiberglass filters, allowing them to capture more particles before needing to be replaced. These filters cost more than fiberglass filters, but they only need to be replaced every 90 days.
HEPA Filters
HEPA (High-Efficiency Particulate Air) filters are the most advanced HVAC filters available. These filters use a dense web of fibers to capture up to 99.97% of airborne pollutants such as bacteria, viruses, and smoke. HEPA filters are commonly employed in hospitals and laboratories where air quality is crucial. These filters are pricey, but they only need to be updated once each year.
Finally, selecting the appropriate HVAC filter is determined by your specific requirements and budget. While fiberglass filters are the least expensive, they are less efficient than pleated or HEPA filters. Pleated filters are an excellent mid-range alternative, while HEPA filters provide the maximum amount of filtration. Regularly replacing or cleaning your HVAC filter is critical to maintaining optimum air quality and extending the life of your HVAC system.
