This Air Filter Selection Guide was developed as a tool for comparing filter options based on specific applications and the type of air-handling equipment used. The guide, which covers over 50 applications, focuses on commercial and industrial categories, including manufacturing facilities, food and pharmaceutical processing, health care, theaters, schools, and gas turbine intake. There are sections devoted to filter alternatives for office buildings and hotels, as well as sensitive processes, such as semiconductor manufacturing, film processing, and paint spray booths. Where prefilters are required or could be used to reduce total filtration costs, the guide offers alternatives for these requirements. A MERV rating for each type of filter allows quick and accurate comparisons, states the company.
