The filter in your HVAC system requires regular replacement to ensure the appliances function efficiently and clean the air. While most people change their filter about once every three months, this schedule can differ depending on the unique circumstances in your household. Below are several factors to consider when determining how often you should purchase new filters.

What Can Change the Schedule of HVAC Filter Replacement?

1. Household Size

The number of people and pets in your home are the most significant factors affecting the overall indoor air quality. For example, if you have several children or animals running around, the filter will accumulate debris faster because there is more dirt, dander, and hair present in the home. Plus, younger family members are more likely to bring in pollen and dust after playing outside, adding further strain to the filter. If you have at least one pet or child, change the filter every two months. With each additional family member, you will need to replace it more often.

2. Allergies

The filter traps contaminants before the HVAC system distributes the air throughout the home. This helps keep the indoor air clean, allowing everyone to breathe easily. However, if you have family members with asthma or respiratory allergies, even small amounts of debris can trigger their symptoms. The best way to prevent this is by changing the filter often, with about once a month being a reliable timeline. This helps the air stay free of irritants.

3. Indoor Air Quality

If you live in a busy area, such as near a major road, commercial site or ongoing construction, the air entering your home will contain more pollution. This forces the air conditioner to work harder to remove the contaminants and provide clean air, which leads to more wear and tear on the internal components. It also makes the filter clog more frequently. To prevent this, inspect the filter once a month and change it whenever it features a gray film.
