LEED is a well-respected third-party verification system   developed by the United States Green Building Council   that offers a point-based rating system for sustainability. Points are awarded in the following categories:


• Sustainable sites

• Water efficiency

• Energy and atmosphere

• Materials and resources

• Indoor environmental quality

• Innovation and design process


Air Filtration and LEED


Indoor Air Quality (IAQ) is a facet of overall indoor environmental quality and is an important aspect of any green building project. A building’s HVAC air filtration system provides tangible ways to ensure high IAQ and energy efficiency and contributes to the completion of LEED credits and prerequisites. In addition, careful selection of the right HVAC filter and filter media can actually save money in the long run – answering critics’ charges that choosing the more sustainable alternatives always have to cost more.


In addition to LEED certification, effective air filtration provides the primary defense for building occupants and HVAC equipment against particulate and gaseous pollution generated within a building, as well as pollutants from air drawn into a building by the HVAC system. Air filters also play a significant role in the energy consumed to operate the HVAC system. The higher the filter’s resistance to air passing through it, the more energy is consumed to operate the HVAC system. That’s why the right filtration strategy can help buildings become more environmentally sustainable and meet LEED and other green building rating system criteria.
