||Six exchangers, installed in office buildings in the northern part of Sweden, were included in this study. Formaldehyde in the indoor air was used as a monitor pollutant and was sampled at 4 positions around the rotor, before and after passage of the rotor, in both the exhaust and supply air streams. Sampling of homogeneous air in the ducts was performed simultaneously with 2,4-dinitrophenylhydrazine-coated glass fibre filters. The analysis of formaldehyde was made by high performance liquid chromatography. The reentrainment of formaldehyde was 1-9%.
