The HVAC filter is an important device that helps prevent too much dirt accumulation on AC and furnace parts. In turn, by keeping parts clean, HVAC efficiency is increased, which translates into lower energy usage. Furthermore, modern HVAC filter types you choose may have a substantial impact on indoor air quality, which is something on the mind of many folks heading into allergy season. What follows are tips to help you decide which HVAC filter types to choose.
Fiberglass HVAC Filter Types
Spun fiberglass HVAC filters are flat-panel filters. They are inexpensive and disposable. Fiberglass filters usually need to be replaced every month, which means more work for you. While they protect HVAC equipment from larger particulates, these filters don't improve indoor air quality very much.
Pleated HVAC Filter Types
Pleated media filters do a much better job of protecting HVAC equipment and improving indoor air quality. Pleated filters offer a larger filtering panel than flat-panel filters, with the same dimensions due to the pleated design.
Pleated filters with a MERV rating of between 8 and 13 are a great choice if anyone in your home suffers seasonal allergies or respiratory ailments. MERV stands for Minimum Efficiency Reporting Value, and it represents a filter's ability to capture airborne particulates. The higher the rating, the better the filter's efficiency.
Thick-Design Pleated HVAC Filter Types
Pleated filters are also available with a special design that gives them more thickness but still allows them to fit inside the standard 1-inch filter slot of most HVAC systems. This filter lasts two to four times longer than a typical pleated filter. If you want this type of filter, ask your HVAC technician if it will fit in your HVAC system.
Electrostatic HVAC Filter Types
Electrostatic air filters are available as disposable or long-lasting washable filters. That's a bonus for many people who want to save money on filters. Electrostatic filters work by using static-cling electricity to attract and trap contaminants to the filter media. This works for all airborne contaminants except gases.
