Finding F-1067
“TVOC concentrations generated from samples B1 (4808 ± 957 μg m–3) and B3 (4140 ± 823 μg m–3), which are the most commonly used KF94 masks for COVID-19 protection, correspond to a high-risk level (health concerns, TVOC = 3000 to 10,000 μg m–3) as established by the TVOC guidelines set by the German Federal Environment Agency concerning Indoor Guide Values (AIR) (der Ad-hoc-Arbeitsgruppe, 2007; Heinzow and Sagunski, 2009; Salthammer, 2011).”
Structure
- Factor
- Total volatile organic compounds (TVOC)
- Setting
- test chamber, KR (immediately after the packaging was opened)
- Study design
- chamber study of the volatile organic compounds released by face masks in Korea: total and individual compounds measured immediately after the packaging was opened, after 30 minutes, after 6 hours and at a raised temperature, for disposable and multi-use masks, with the inhaled mass estimated from the mass flow rate (class 4)
- Effect
- mean 4808
- Caveat
- a chamber measurement of the product, not a room concentration
