Structure

Factor: Total volatile organic compounds (TVOC)
Intervention: Air purifiers
Setting: hotel guest room, TW
Study design: tests of movable air cleaners in hotel guest rooms in Taiwan: total volatile organic compounds, carbon dioxide, bacteria and fungi measured in three rooms before and during the operation of two brands of air cleaner, against the indoor air quality values of Hong Kong and Taiwan (class 3)
Effect: other 102.2
Caveat: a removal rate in one hotel room, not a room concentration
