A simple schedule
Colorado's wind, dust and dry air load filters faster than in many places. Check yours monthly during heavy heating and cooling seasons.
- 1-inch filters: every 1 to 3 months
- 4 to 5-inch media filters: every 6 to 12 months
- Pets, construction nearby, wildfire smoke or allergies: check monthly
Picking the right filter
The size is printed on the side of your current filter. Mid-range MERV 8 to 11 filters balance clean air and airflow for most homes. Very restrictive filters can choke airflow on some systems, so ask your technician if you're unsure.
Why it matters
A clogged filter makes the system work harder, raises energy bills, and can cause furnaces to overheat or AC coils to freeze.
