 Yet air filtration is very important, ensuring a safe environment for countless workers and the public.
 In a hospital environment when it comes to eliminating hospital acquired infections, such as MRSA (methicillin resistent staphylococcus aureus), air filtration is a vital tool.  Would this development and deployment of air filtration in hospital environments not have come much sooner if it wasn't for ASH's negativity?

 Prof. Med. Grieshaber raises the issue of air pollutants being the cause of lung cancer in chefs in commercial kitchens, but also bakers in his book “Götterdämmerung der Wissenschaft”<ref>PublikomZ, 2012, p.44</ref>:
-<blockquote>''“The air pollutant sources in kitchens and bakeries are well known to the BGN (Berufsgenossenschaft Nahrungsmittel und Gastgewerbe), as we have spent a long time dealing intensively with them. Ventilation and air conditioning has been also an issue for the BGN for a long time, long before technical solutions for non-smoker protection became an issue of interest.

Ventilation and air conditioning has been also an issue for the BGN for a long time, long before technical solutions for non-smoker protection became an issue of interest.
 Conventional ventilation and air condition installations in kitchens usually transport the hazardous materials right past the airways of the chefs before they are being passed into the air. Therefore our experimental and research work concentrated on developing a ventilation type and making it operational, with which this can be avoided.
-The results of our research were installations, which are based on the principle of layer ventilation. Such systems are naturally not only suited to eliminate the carcinogens produced during cooking and baking, but the principle is also applicable for use in smoking areas. Tests with such equipment installed in catering businesses have already taken place and in our opinion the results were convincing”''.</blockquote>

-<blockquote>'''"Only the zero exposure ensures health. This should be achieved. No however cleverly devised ventilation system can be an effective equivalent."'''</blockquote>

 Does this also apply for potentially lethal micro-organisms and e.g. cooking fumes/smoke?

 Gibb et al concluded:
-<blockquote>"Cumulative hexavalent chromium exposure was associated with an increased lung cancer risk; cumulative trivalent chromium exposure was not. '''The excess risk of lung cancer associated with cumulative hexavalent chromium exposure was not confounded by smoking status.''' The current study offers the best quantitative evidence to date of the relationship between hexavalent chromium exposure and lung cancer.”</blockquote>
