Air Filter Solution for Museums and Libraries

Museums and libraries have the responsibility of preserving and displaying our history, science, and knowledge from the beginning of time to present day.  In order to achieve this unique task, preservation standards and guidelines must be put in place to prevent the degradation of ancient artifacts and delicate manuscripts.  Of these standards, air filtration is considered one of the most critical.


  • The facilities typically use two stages of particulate filtration along with some form of molecular filtration.

  • HVAC systems in older buildings may not allow for as many stages of filtration as easily.

  • It is possible to achieve the stages of filtration needed for museum quality air with just about any type of air handler.

  • Pleated prefilters, minipleat, V-Cells, and box filters are common particulate filters in museums or libraries.

  • MERV 15 is an optimal particulate filtration for most museums, although there are some that require HEPA filtered air.

  • Molecular contaminants such as ozone, acids, sulfer dioxide, nitrogen dioxide, and exhaust fumes can destroy priceless items stored in these facilities.

  • These impurities can be controlled with loose carbon and potassium permanganate or high efficiency gas adsorbent medias.

  • Any space limitations within your air handler can typically be resolved using combination filters to eliminate both particulate and molecular contamination.
