3M Filtrete Air Filter

These filters are designed to last up to three months. For optimal system performance and air quality, we recommend checking them at the three-month mark and replacing them if they appear visibly dirty.

A MERV 11 rating indicates that this filter is highly effective at capturing microscopic particles, including pet dander, pollen, smoke, and dust. It strikes a balance between high-level filtration and maintaining proper airflow for your HVAC system.

No, these are single-use, synthetic filters. They are not designed to be washed, and attempting to clean them will damage the electrostatic fibers and reduce their effectiveness.

These filters are engineered to balance filtration efficiency with airflow. While they capture smaller particles than standard fiberglass filters, they are designed to work with most residential HVAC systems without putting undue strain on your blower motor.

This specific model is designed for allergen defense rather than odor reduction. While it will trap the particles that often carry odors, it does not contain activated carbon or other materials specifically meant to neutralize smells.

Before purchasing, check the dimensions printed on your current air filter or measure the slot in your furnace or air handler. This filter measures 20 inches by 14 inches by 1 inch; it is crucial to match these dimensions exactly to ensure a proper seal.
