Filtrete Air Filter

A MERV 12 rating indicates a high level of filtration efficiency. It is capable of capturing not just large particles like dust and lint, but also smaller contaminants like bacteria, virus-carrying particles, and pet dander, making it a significant step up from standard fiberglass filters.

The filter material is engineered to carry a static charge that acts like a magnet for airborne particles. This allows the filter to actively attract and trap microscopic pollutants as air passes through, rather than relying solely on the physical density of the filter media.

While higher-rated filters are denser, this Filtrete model is designed to balance effective filtration with proper airflow. However, because it captures more particles, it is important to check and replace the filter regularly to ensure your HVAC system continues to run efficiently.

For optimal performance and to maintain good indoor air quality, we recommend replacing these filters every three months. If you have pets, allergies, or live in a dusty environment, you may need to change them more frequently.

These are standard-sized filters measuring 16 x 25 x 1 inches, designed to fit most residential HVAC systems that use 1-inch thick filters. Always measure your current filter or check your system's manual to confirm the exact dimensions required before purchasing.
