It might seem like a simple component, but your HVAC filter plays a critical role in your system’s performance and your indoor air quality. A clean, properly selected filter helps ensure your HVAC system runs efficiently, lasts longer, and provides healthier air for your home or business. Naturally, this leads to a lot of questions—so we’ve compiled answers to the five most common ones.
The frequency depends on the type of filter and the environment in your home or business. In general, filters should be replaced every 1 to 3 months. However, if you have pets, allergies, or live in an area with high pollen levels, you may need to check and replace it more frequently. If you're on a regular maintenance schedule, your technician will typically change the filter during those service visits, helping you plan accordingly.
Your filter choice should align with your air quality needs and system specifications. Filters with higher MERV (Minimum Efficiency Reporting Value) ratings capture more airborne particles—but they may reduce airflow and need to be changed more often. For most homes, a MERV rating between 8 and 13 strikes a good balance between filtration and efficiency. Always check your system’s manufacturer guidelines or consult with your HVAC technician to ensure compatibility.
Yes. A clogged filter restricts airflow, forcing your HVAC system to work harder to maintain the desired temperature. This extra effort results in increased energy consumption—and higher utility bills.
Some filters are reusable and designed to be washed, while others are disposable and should never be reused. Always check the packaging or product specifications before attempting to clean a filter.
High-end filters may provide superior filtration, which can be beneficial for individuals with allergies, asthma, or other respiratory concerns. However, for most households, a mid-range filter that’s replaced regularly will offer sufficient protection and performance without the added cost.
