23. Advanced air purification
Some circumstances justify greater investment in air purification strategies. For example, proximity to highly traveled roads, manufacturing plants and seasonal variation can affect outdoor air quality, increasing ozone and VOC content, and in turn diminishing indoor air quality. Similarly, climates with high humidity levels and inadequate indoor ventilation can foster the development of mold and spores in indoor environments.
This feature requires the use of carbon filters to remove VOCs and ozone, and ultraviolet sanitizers to irradiate any bacteria, viruses and mold spores present in circulating indoor air.
To reduce VOCs in the indoor air, buildings which recirculate air use one of the following methods:
Spaces with more than 10 regular occupants, within buildings that recirculate air, use one of the following treatments or technologies to treat the recirculated air, either integrated within the central ventilation system or as a standalone device:
As evidence that the selected filtration/sanitation system chosen continues to be fully operational, projects must annually provide IWBI with:

The EPA's "Residential Air Cleaners" notes that properly designed UVGI cleaners in typical airstream disinfection applications could reduce the viability of vegetative bacteria and molds, and could provide low to moderate reduction in viruses. |
| 23.2.b |
The EPA's Residential Air Cleaners document notes that photocatalytic oxidation cleaners are intended to change gaseous pollutants and associated odors into harmless products. |
