Statement from the Passive House Institute | April 2020
The Passive House Institute strongly recommends continued use of fresh outdoor air ventilation systems (MVHR) with proper filtration—especially during the COVID-19 pandemic—as they ensure clean, low-risk indoor air, unlike recirculated air systems, which should be minimized.
