- This paper presents some of the results of a second-hand tobacco smoke intervention studycarried out in 19 flats in four different buildings. Two of the investigated buildings were nonrenovatedand two others were renovated. The aim of the study was to quantify infiltration ofultrafine particles from a smoker's flat into a non-smoker's flat. In addition, several tests werecarried out to describe some solutions for reduction of particle concentrations in the smoker'sflat and the non-smoker's flat. The air change rates and the indoor particle concentrationswere measured continuously during the measuring periods. The particle sources (particlegenerating activities) were cigarette-burning in the un-occupied buildings and candle-burningin the occupied buildings. Reductions of the concentration of ultrafine particles using aircleaning devices were studied. Results showed that the transfer of ultrafine particles wasabout 9% when the source flat was located below the receiving flat, whereas the transfer was1-2% when the source flat was on the same floor as, or above, the receiving flat.

Conference paper (other academic/artistic)abstract
- The purpose of this study was to investigate how the effectiveness of portable air cleaners(ACs) against tobacco smoke is influenced by the clean air delivery rate (CADR), the locationof the AC in relation to the pollution source and the apartment structure. The study was basedon field experiments and simulations with the CONTAM software. The AC effectiveness wasabout 80% for one AC, and 93% for two ACs in the studied apartment (volume=110m3).Ultrafine particles (UFP) exposure in a room without tobacco smoking (clean room) could bemuch less than in the source room if these rooms were not directly connected with each other(but indirectly connected via doors open to other rooms). Operating the AC in one of therooms without cigarette smoking could develop a partly isolated clean environment.However, this led to a rather low cleaning effectiveness for the concentration of ultrafineparticles in the apartment as a whole. If operating the AC in the room where cigarettes arebeing smoked, the UFP exposure in the whole apartment can be further reduced.
