    What do our Air Purifiers remove from the air?


    STAGE 1 | Technostat® high-efficiency pre-filter
    Designed to remove ambient fine dust particles from the air and increase the lifespan of the HEPA and Activated Carbon filters.

    Technostat® is used in many medical applications which demand some of the highest levels of filtration since they are often used in life-support and human ventilation machines.*

  • BFE Efficiency > 99.9992%
  • VFE Efficiency > 99.9970%
  • Filter life: 1 - 3 years continuous use**

    *Tested in accordance to Spec MIL-M-36954C By Nelson Labs

    Filter life: Up to 6 months continuous use**

    STAGE 2 | H13 Medical-grade HEPA filter
    With an incredible 6.4m² surface area normally found in commercial filters used in hospitals and clean rooms. The HEPA filter in the E20 Plus provides the highest level of filtration available. Certified at 99.97% @ 0.3 microns -tested down to 0.003 microns at 100% efficiency*. The HEPA filter removes viruses, bacteria, mould spores, allergens, pollen and dust mites before passing the air on to the third stage filter.

    Filter life: 3 - 5 years continuous use**

    STAGE 3 | Coconut based Activated Carbon final stage filter
    An unprecedented 6kg activated carbon final stage filter, manufactured for commercial-grade applications requiring heavy-duty chemical & odour removal. This filter is designed to remove chemical pollutants, volatile organic compounds (VOC’s), smoke, road pollution and odours before the purified air is released back into the room through the High-Flow™ air diffuser.


  • Large filters not only result in superior filtration and airflow, they also result in: 
  • Lower energy consumption
  • Longer filter life
  • Less environmental impact 
  • Lower cost of air purifier

    Certified 99.97% minimum efficiency at 0.3 microns (tested down to 0.003 microns @ 100% efficiency)* 
    * Tested by LMS Technologies Inc, 2017 (EN1822)

    **Based on 60% daily usage over 5 years, or continuous usage over 3 years in environments with average particulate/chemical levels. As operating conditions vary based on levels of dust, chemicals & odours present, and system proximity to major pollution sources, InovaAir does not warranty consumable filter life.
