Box Filters

The first high-efficiency box filter was invented — by AAF — 60 years ago. Today we’ve advanced these filters to provide a high level of protection in a small footprint. These box filters can reduce fine contaminants in critical applications and protect against small particles that carry viruses and bacteria. The space-saving design helps reduce costs of shipping, storage and handling.
