It’s a good idea to take a closer look at the air quality in your home to determine how often you should replace the filters. According to David Heiman, several factors play a role in the frequency. “Living conditions such as dry, dusty climates and pet dander will significantly impact the frequency of how often you need to change your air filters.” If you tend to have a lot of dust in your home for any reason, that could be a sign that it needs changing more often since these particles may be coming into those living spaces from the HVAC system.
Dogs, cats, and just about any other animal can be significant factors. Heiman states, “When pets shed, the hair and dander get airborne and is sucked up into the filter, which clogs the filter, reducing airflow and system performance.” The easier air can move into the system, the less energy it needs to function, which is why a well-maintained filtration system saves you money on lower energy costs.
