Air Filters for Business to Business Education

Identify Contaminants to be Removed Is there clear understanding of what is really there? Is there data to support the findings? – (has testing or other quantification been completed?) Are there dynamics of process/technology changes? – (are there projects active that could heighten or diminish the need for filtration?) Are all forms of contaminants considered? – (are solids liquids and gases, including micro biological elements, all part of the decision process?) Are there Hazardous materials involved? What kind of materials and what are the concentrations? – (is there data to support the judgment?) Are other exposure control options considered? – (are special protective gear or isolation protocols a better solution?) Is expended or used filter disposition an impact? – (were costs and complexity of contaminated filter removal considered?) Has source control been considered as an alternative to filtration? Are sources easily identified? – (is there evidence to support the judgment?) Are control options viable and practical? – (has cost/benefit vs. filtration been considered?) Have ventilation techniques been considered as an alternative to filtration? Are acceptable fresh air sources available? – (is there evidence to support the judgment?) Is re-circulated air acceptable? – (is it in sufficient quality and quantity?) Is the air handling equipment capable? – (can fresh air make up or re-circulated sources be introduced?)
