High Air Flow (HAF) Air Filters

The open channel construction of 3M High Air Flow (HAF) Air Filters offers low initial airflow resistance while its unique microstructure and electrostatic charge provide effective particle capture and retention. This may translate to fewer filter changeouts, reduced coil cleaning, and/or reduced maintenance cost. 

3M™ HAF Air Filters may offer an ideal alternative in applications where regular filter replacement is difficult or impractical, but where low airflow resistance is important.

Developed using innovative 3M technologies, 3M HAF Air Filters are frameless, self-supporting, and are constructed from an array of open flow channels. These filters are electrostatically charged for enhanced parti cle capture and retention.

3M HAF Air Filters are available with an antimicrobial agent to help inhibit the growth of mold and mildew on the filter media. Users should be aware that mold and mildew may grow on captured particles that build up over time on the filter.

Versatile performance in a wide range of applications

For hospitality building owners and managers, maintenance time and productivity play an important role in efficient building operation. 3M HAF Air Filters have been shown to help capture airborne dust that can deposit on in-room heating and air conditioning units, while maintaining good airflow through the unit. In addition, due to their self supporting design, 3M HAF Air Filters are easily installed and replaced.

For manufacturers of industrial equipment and electronics, airborne dust and dirt can damage various components, resulting in increased maintenance. In addition, maintaining good airflow in these units is of utmost importance. Because of their frameless, self-supporting construction, 3M HAF Air Filters can easily be adapted to many existing equipment configurations, providing a simple way to add value to the equipment design.
