Ventilation for control of formaldehyde in mobile homes.

Examines what adequate ventilation rates are needed to control indoor levels of formaldehyde. Concludes that the ventilation rate procedure of ASHRAE Standard 62-1981 "Ventilation for Acceptable Indoor Air Quality" offers protection from expected formaldehyde outgassing rates. Since formaldehyde outgassing decreases with time, increased ventilation during the first 2-3 years of the life of a structure is desirable. More data is needed to establish what the outgassing rates are and how they vary with temperature.
