The 90-PLUS Residential Air Filter System

90-PLUS is a proprietary high-efficient system designed specifically for residential heating and cooling equipment. Your HVAC professional can modify your existing equipment to incorporate the 90-PLUS unit.

Under normal conditions, the 90-PLUS filter will last 9-12 months before replacement is needed. 90-PLUS filters are also available with activated charcoal to help control household odors.

90-PLUS replacement filters are available from your HVAC professional, or directly from Nebraska Air Filter.
