“…Homes likely contain a range of formaldehyde-containing materials, but the fastest timescales (higher kL) will tend to dominate the effective value for a home (Sherman and Hult, 2013). The values of kL here are comparable to the values of 0.15-0.18 h À1 from in-home measurements reported by Hun et al (2013).…”

“…In contrast, Offermann (2009) presented data showing indoor formaldehyde concentration decreasing as air exchange rate increased in a cross-sectional study of new California homes. Recent findings suggest supply ventilation may be substantially more effective than exhaust ventilation at lowering residential formaldehyde concentrations (Hun et al 2013).…”

Formaldehyde and acetaldehyde exposure mitigation in US residences: in‐home measurements of ventilation control and source control

et al. 2014

Measurements were taken in new US residences to assess the extent to which ventilation and source control can mitigate formaldehyde exposure. Increasing ventilation consistently lowered indoor formaldehyde concentrations. However, at a reference air exchange rate of 0.35 h -1 , increasing ventilation was up to 60% less effective than would be predicted if the emission rate were constant. This is consistent with formaldehyde emission rates decreasing as air concentrations increase, as observed in chamber studies. In contrast, measurements suggest acetaldehyde emission was independent of ventilation rate. To (OEHHA 2013) may require combining source control with ventilation. Ventilation rates could be increased during the first year after construction when VOC concentrations tend to be highest.
