The claim that a building which allows smoking requires “tornado-level ventilation” in order for it to be made “safe” for nonsmokers was first made by James Repace, a prominent and fanatical anti-smoking activist since the 1970s.
. . . . .A remarkable coincidence? Not a bit of it. Look again at where the crucial figures of 9 and 5.4 came from. 9 ccpm/occ is the ASHRAE indoor air guideline and 5.4 (60% of 9) is the recommended number of air changes pertaining to 9 cfm/occ. Now think of a number, any number. Let’s say, for instance, that ASHRAE required a whopping 1,000 cpm/occ indoors and, therefore, 600 air changes per hour. Now do what Repace did. First take the figure of 202,500, divide it by 1,000 ( =202.5) and multiply it by 600. What do you get? That’s right: a tornado level of 121,500 air changes per hour. No matter what number you start with, you will always end up with 121,500 because the equation will only ever give you 60% of 202,500. And so, whether ASHRAE requires one cubic foot of fresh air or a million, Repace’s equation will always tell you that you need a tornado.

Well the Orick Vacume Cleaner boasts the force of two huricainces, and boasts that it cleans the air while it vacumes. They use a smoke filled chamber in their demo. Problem solved – all you have to do is get one of those vacume cleaners, stick it in a corner, and leave it on.
These machines are better!
