Most 16x25x1 furnace filters need to be changed every two to three months, but this can vary depending on your lifestyle and usage. It is recommended that regular fiberglass filters be swapped out every 30 days. Pleated filters can last three to six months, while thicker filters can last up to nine months or even a year. However, experts suggest changing the filter once a month if it is made of fiberglass.
The primary purpose of a heating filter is not to purify the air you breathe, but to clean the air that passes through the boiler and other air conditioning equipment. Dirty or clogged filters can reduce filter efficiency and overload the air conditioning system, leading to damage. To guarantee that your home's air quality is good, monitor filter conditions, understand your living space requirements, and adjust how often you replace filters accordingly. Most homeowners are aware that they must change their air filter regularly in order to maintain a healthy central air system in their home.
