HEPAirX®: Ventilating Room Air Purifier

HEPAirX® is a ventilating room-air purifier that quickly and effectively dilutes, filters and reduces indoor pollutants that are often cited as causes of asthma, respiratory irritations and allergic reactions.

HEPAirX combines the three primary strategies for Indoor Air Quality improvement into one packaged unit:

Filtration – HEPA grade filters in indoor and outdoor air streams recirculating 7 to 9 room air changes per hour in averaged sized room of 1000 cubic feet.

Ventilation – exhausting of room air and replacing with fresh outside air approx 2 times per hour to remove gaseous contaminants such as VOC’s, CO2, CO, formaldehyde, etc. Energy efficient due to air to air heat exchanger in the exhaust and outside air streams.

Isolation – isolates the room from adjacent spaces by creating a slight positive pressure and physical sealing of openings or connections to central HVAC system. This prevents re-contaminating the room from activities outside the room. Only possible because of heating, cooling and de-humidifying capability of the HEPAirX.

The unit is a uniquely integrated combination of an energy recovery ventilator, high-efficiency particulate air (HEPA) filtration, heater and air conditioner that is conveniently window-mounted.  These features are important because they allow the room to be treated separately from the rest of the house.  This prevents the home’s heating and cooling system from continuously re-contaminating the air with pollutants.  Also, by isolating the room and providing a slight positive pressure, good air quality can be maintained by mixing and re-circulating room and fresh, outside air continuously through the HEPA filter.

Within minutes, the unit removes and reduces ultra-fine airborne particulates from cooking, sneezing and animal dander that drift around in the air for hours and are easily stirred up with minimum amount of activity.  A second category of contaminants that HEPAirX addresses are gaseous compounds like carbon dioxide, carbon monoxide and volatile organic compounds (VOCs) like formaldehyde.  The VOCs are mostly by-products of chemicals used in fuels and building materials such as plastic and paint; even electronic equipment like computers continuously release VOCs over time.

Good indoor air quality (IAQ) is critical to maintaining good health.  According to the U.S. Environmental Protection Agency, “Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes.  Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home.”

Poor IAQ linked to the high incidence of asthma, a disease that afflicts more than 22 million Americans, including 6.5 million children.Front view of HEPAirX Ventilating Room Air Purifier
