Check your existing filter — the size is usually printed on the frame. If not, measure length, width, and depth (in inches) to find the correct replacement.
It depends on filter size, MERV rating, and your home’s conditions. Many homeowners replace every 60–90 days under average use. If you have pets, allergies, or high system use, you may need to change more often. Some high-efficiency filters can last 6–12 months in mild conditions. Always check your manufacturer’s recommendations for the best schedule for your system.
MERV (Minimum Efficiency Reporting Value) shows how well a filter captures particles between 0.3–10 microns. A MERV 8–11 is a great balance for most homes (dust, pollen, pets), while MERV 13+ is better for allergy, asthma, or smoke concerns — if your HVAC system can handle the higher airflow restrictions.
They can if your system isn’t designed for them. Higher MERV filters block more particles but may reduce airflow. Always check your system’s specs or manual before moving up.
