Greentek’s Whole House HEPA System is the Best Residential Air Cleaner on the Market


Works in conjunction with your heating, ventilation, and air conditioning (HVAC) system, as well as stand-alone.

Variable Speed Settings

Variable speed settings give you the convenience of operating your unit at a maximum filtration or at a lower rate.

Ultra-Quiet Operation

Our unique design places filters on either side of the motor, creating a double sound barrier to run quietly and efficiently. In addition, the entire unit casing is lined with insulation, and rubber mounts isolate the motor from the cabinet.

Easy Maintenance

  • Maintenance is a breeze with our modular construction.
  • The pre-filter, carbon filter and HEPA media filter slide out for easy replacement.
  • On average your pre-filter and carbon filter need to be replaced every 3 to 6 months.
  • Your HEPA filter needs to be replaced every 2 to 5 years.
