Fantech HERO HS300 HEPA Filtration System

The HERO HS300 whole-house HEPA filtration system provides full-spectrum air cleaning by removing pollutants and allergens from the air circulating within your home. The pre-filter with carbon will collect up to 90% particles between 3-10 microns in size, such as pollen, dust, lint, dust mites, pet dander. The activated carbon filters out odor-causing particles from the air, such as cooking odors and smoke. The HEPA filter arrests up to 99.97% particles as small as 0.3 microns in size, such as bacteria, legionella, combustion smoke, milled flour, mold spores.

The HERO HS300 is designed to install directly on the return air plenum of the forced air heating/cooling system. If you choose this type of installation, it is recommended that you run the fan on your forced air system continuously (Fan On mode) to maximize the cleaning effect. Alternatively, the HERO HS300 can be installed using 8 inch round collars for application requiring ducting using the included two 8" round collars, two mounting brackets for wall and fasteners.

• Two speed operation (200/280 cfm)

#1 Q:   Do they list how loud the unit is running?
A:   Fantech does not list sound levels for this product. It is typically attached to the furnace return by the furnace so installation will vary the actual sound level. In our experience these are quiet, especially when installed with the flex duct on the in and out ports.
