Whole-House, Two-Stage Filtration System

Fantech says its Hero HS300 whole-house HEPA filtration unit removes up to 99.97% of particles 0.3 microns and larger from the air circulating within a home. The unit has two-stage filtration—a pre-filter with carbon and a HEPA filter—to remove pollutants, allergens, odors, and viruses, according to Fantech. It can be installed on the return air plenum of a forced air system or as part of a stand-alone ventilation system. Suggested retail price is $570. fantech.net
