IQAir HealthPro Series PreMax Pre Filter

This powerful Swiss-made filter controls coarse particles while eliminating micro-particles like pollen, pet dander and mold spores. The patented knife-edge seal technology ensures that 100% of air flows through the filter with no system leakage. The filter is made with non-woven glass micro-fiber and non-off-gassing separators and is mini-pleated for high capacity to help protect the product's subsequent filters. The filter lasts up to 18 months when the unit is on fan speed three for 10 hours a day.
