Is your building return-to-work ready?

Take the right steps in ensuring that your building is return-to-work ready.


HVAC systems impact the spread of COVID-19 so it important that the right steps are being taken to help reduce the spread. We – and TSI Incorporated – are here to help you learn how.



  • Consider your ventilation system
    • Increase the outdoor air-percentage to increase dilution of contaminants and eliminate recirculating, whenever possible
    • For heating-ventilation-air-conditioning systems that recirculate air, businesses need to improve central-air filtration
    • Replace and upgrade air filters prior to re-occupancy
    • Run systems on full economizer


  • Humidity and virus transmission
    • Increased indoor humidity is only possible if the HVAC system has the capacity to meet the recommended levels. Additional humidification or dehumidification capacity may also need to be added.
