Title The effect of air cleaners on tobacco smoke - Part II. Long-term test and complementary measurements
Original title Luftrenares effekt på tobaksrök - Del II. Långtidsprov och kompletterande mätningar [in Swedish]

Abstract A long-term test was conducted by loading 3 different room air cleaners with smoke from 20, 200, 400, 600 and 800 cigarettes and measuring their ability to remove gases and particles from the contaminated air. The measurements covered particles from 0.01 to 7.5 microns and gases: carbon monoxide, ammonia, formaldehyde, nitric oxide, nitrogen dioxide, hydrocarbons and hydrogen cyanide. The cleaning efficiencies for particles were approximately constant, while the cleaning efficiencies for the gases decreased considerably with increasing smoke load. The report also describes measurements of the ability of the air cleaners to remove acrolein, the pH of the activated charcoal in the air cleaners, the emission of gases and particles from room air cleaners contaminated by cigarette smoke, and from smoke deposition on room surfaces. The first part of this study was published as Arbete och hälsa 1987:28 (CIS 89-1962).
