Things To Keep In Mind

• MERV And MPR Ratings: When choosing an air filter, consider its MERV (Minimum Efficiency Reporting Value) and MPR (Microparticle Performance Rating). For most homes, a MERV rating between 8 and 13 is ideal. The MPR rating, ranging from 600 to 2200, shows how well the filter traps tiny particles.

Maintaining Your 21x23x1 Air Filter

Regularly checking and replacing the 21x23x1 air filter is essential to keeping your HVAC system running smoothly. Inspect the filter monthly and replace it every three months, or sooner if it looks dirty. Doing this will help ensure the filter continues to capture particles effectively and allows your HVAC system to run efficiently, keeping your indoor air clean and comfortable.

Important Precautions

• Filter Lifespan: The life of an air filter depends on factors like air quality and how often your HVAC system is used. In homes with pets or high levels of dust, filters may need to be replaced more frequently.
• Correct Fit: Ensuring the air filter fits your HVAC system correctly is crucial. An improperly sized filter can leave gaps, allowing unfiltered air to bypass the filter and reduce its effectiveness. Always measure your existing filter before purchasing a new one.
• Proper Airflow: A clogged filter or one that doesn't fit correctly can block airflow, causing your system to work harder and use more energy. Replacing your 21x23x1 air filter regularly ensures smooth airflow and helps keep your system running efficiently.
