A total smoking ban is not a workable option, according to the Air Cleaner Manufacturers Association. An ACMA report to the Department of Health proposes exempting premises exempted from a smoking ban if air cleaners are installed "The industry recognises that a total ban on smoking is unlikely, as is the status quo, so regulation is likely," said Honeywell, the air cleaner manufacturer and ACMA member. "Air cleaners can minimise the practical difficulties and allow smokers and non-smokers alike the opportunity to enjoy clean air. As we state in the ACMA dossier, an air cleaner costs only about £1 per day to run."
