HERO HEPA Whole House Filtration System (280 CFM)

The Fantech HERO HS300 (model HEROHS300) is a dedicated whole house HEPA filtration system that delivers 280 CFM of filtered air throughout your home. This system captures 99.7% of airborne particles down to 0.3 microns, including allergens, dust, pollen, and smoke, using a true three-stage filtration process. Designed for both conditioned spaces like basements and closets, and unconditioned areas such as garages and attics thanks to its insulated cabinet, the HERO HS300 integrates directly with your HVAC system to provide continuous air cleaning without occupying living space. It replaces earlier Fantech models DM3000P, CM3000I, and CM3000.

• Three-Stage Filtration System: The HERO HS300 uses a pre-filter, activated carbon filter, and true HEPA filter working in sequence. This layered approach captures large particles first, then neutralizes odors from tobacco smoke and cooking, and finally removes 99.7% of particles down to 0.3 microns for comprehensive air quality improvement throughout your home.

• True HEPA Filter (99.7% at 0.3 Microns): The HEPA filter meets the industry standard for high-efficiency particulate air filtration. This means it removes airborne allergens, dust, pet dander, mold spores, and even some viruses from the air circulating through your heating and cooling system, making it especially valuable for households with allergy or asthma concerns.

• Activated Carbon Filter for Odor Control: The carbon filter stage adsorbs and neutralizes tobacco smoke, cooking odors, and other household smells. Fantech recommends replacing the carbon filter every three months to maintain optimal odor removal and protect the HEPA filter from premature clogging.

• 280 CFM Airflow Capacity: The built-in motor moves 280 cubic feet per minute of air through the filtration stages. This airflow rate is sized to provide effective whole house filtration for typical residential applications when integrated with your furnace or air handler.

• Insulated Cabinet for Flexible Installation: The cabinet is insulated, allowing installation in unconditioned spaces like garages, attics, or unheated crawl spaces without condensation concerns. You can also mount it in conditioned areas such as basements or utility closets, giving you installation flexibility based on your home layout.

• Dual Mounting Options: The HERO HS300 offers duct-mounted installation or direct connection to your furnace or air handler using the included back plate. The back plate method eliminates the need for ductwork fittings at the unit connection point, simplifying installation when mounting directly to HVAC equipment.

• Relay-Activated Operation: The system activates automatically when your furnace or air handler runs, controlled by a relay switch. This coordinated operation ensures filtered air circulates whenever your HVAC system is conditioning your home, with no separate controls to manage.

• Removable Power Cord: The HERO HS300 includes a removable 5-foot cord with a standard 3-prong plug. This design allows you to remove the cord during installation or maintenance, and provides flexibility in routing power to the unit location.

The HERO HS300 requires 120V electrical power at 1 amp and connects to any furnace or air handler equipped with a relay switch for coordinated activation. The unit uses 8-inch duct connections (the included plastic collars can be replaced with aftermarket galvanized 8-inch collars if preferred). It is designed for residential whole house applications and can be integrated into forced air heating and cooling systems.

The HERO HS300 can be installed in conditioned spaces (basements, closets, heated crawl spaces) or unconditioned spaces (garages, attics) due to its insulated construction. Installation methods include duct mounting or direct attachment to a furnace or air handler using the provided back plate for relay-switched operation. Replace the carbon and pre-filter (SKU 463046) every three months. Replace the HEPA filter (SKU 463048) as needed based on usage and air quality, typically annually in residential applications. The cabinet door provides access to all three filter stages for maintenance.

A: Yes, whole house HEPA filtration systems like the Fantech HERO HS300 are highly effective. The HERO HS300 uses a true HEPA filter that captures 99.7% of airborne particles down to 0.3 microns, including allergens, dust, mold spores, pet dander, and pollen. By integrating with your furnace or air handler, it filters air continuously throughout your entire home rather than just a single room, addressing airborne irritants and allergens at the source of your home's air circulation.

A: HEPA filters can reduce asthma triggers by removing airborne particles that commonly worsen asthma symptoms. The Fantech HERO HS300 captures 99.7% of particles down to 0.3 microns, including dust mites, pollen, mold spores, and pet dander, all recognized asthma triggers. The activated carbon stage also removes odors and smoke that can irritate sensitive airways. While filtration is not a medical treatment, removing these airborne irritants from your home's air circulation can contribute to a cleaner breathing environment.
