Some filters are marketed as “3-month,” “6-month,” or even “1-year” filters. But the truth is, every house is different.
Things like pets, dust infiltration, traffic in and out of the home, construction, and even the location of the house can all affect how quickly a filter gets dirty.
Some homes may be perfectly fine changing their filter every 6 months, while others may need theirs replaced every couple of months.
Don’t rely solely on the timeframe printed on the filter. As you live in the home, periodically check it and you can eventually determine a schedule that works for your specific house.
A good rule of thumb: you should be able to see clear, visible light through the filter. If the filter is so dirty that the light coming through is very dim or difficult to see, it’s likely time to replace it.
A dirty filter can restrict airflow through your HVAC system, making it work harder and potentially costing you more in the long run.
Hope this helps—and maybe saves you some money down the road! 🏠❄️
