HEPA Upgrades for HVAC Systems

Upgrade your HVAC system with HEPA air filters to keep your indoor air free from viruses and people safe.

Ever since the Sars-CoV-2 virus outbreak, the economy finds itself out of balance and kind of in a waiting mode all over the globe. Many business owners have been mandated to close down their business, as the risk of a COVID-19 infection is simply too high indoors. The pandemic has brough regular HVAC filters to their limits as they no longer provide sufficient protection for people inside of buildings - at least not from viruses and bacteria.

Different studies provide detailed analyses about the risk of infection with Sars-CoV-2 in different indoor environments under various conditions:

  • People wearing a mask
  • People not wearing a mask
  • People being active
  • People not being active
  • With ventilation systems
  • With adequate aeration possibilities
  • With running HVAC systems
  • With HEPA air purifiers

All studies come to at least one joint conclusion: Meeting people inside is not safe any longer (Position paper of the Gesellschaft für Aerosolforschung on understanding the role of aerosol particles in SARS-CoV-2).

At least it is not if  

  • Distances can´t be kept
  • Hygiene rules are not being adhered to
  • Masks are not being worn or not worn correctly
  • Windows cannot be opened /cross-aeration is not possible and
  • Inadequate air filtration solutions are installed

Upgrading existing Heating Ventilation and Air Conditioning Systems (HVAC) to High Efficiency Particulate Air Filter (HEPA) grades is one option to tackle this threatening challenge. Nevertheless, many filter suppliers only provide HEPA filters made of micro-glasfiber, which usually results in significantly elevated pressure drop. This again leads to the fact that upgrades of HVAC systems are not necessarily easily done - especially not without major, costly and time consuming re-configuration work on your filtration system.
 
MANN+HUMMEL offers a new HEPA* upgrade solution for HVAC systems using ePTFE membrane media. These ePTFE HEPA filters allow for an easy upgrade of existing HVAC systems without system reconfiguration and also in air recirculation mode. The ePTFE media provides HEPA supply air quality at energy levels only minimally higher than in pre-Corona filter configurations.
