3M™ High Air Flow (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 filters are constructed from an array of open flow channels, are frameless and self-supporting. These filters are electrostatically charged for enhanced particle capture and retention.
Refer to for more performance information. 3M HAF air filters are available with an antimicrobial agent to help inhibit the growth of mould and mildew on the filter media. Users should be aware that mould and mildew may grow on captured particles that build up over time on the filter.
For hospitality building owners and managers, maintenance time and productivity play an important role in efficient building operation. 3M HAF 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, HAF 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 filters can easily be adapted to many existing equipment configurations, providing a simple way to add value to the equipment design.
For operators of transit systems in congested urban centres, soot and dust can clog HVAC filters and coils, resulting in the need for frequent service intervals and filter replacement. Due to the unique combination of low pressure drop and good dust loading, 3M HAF filters may be an excellent filter for these applications, particularly compared to conventional foams, plastic netting or metal screens.
In these and other applications, filtered air can be an important competitive advantage that does not require a major capital investment.
