Whether integrating into hand washers, in ceiling light fixtures or public restrooms, UV may become a promising tactic in a building’s fight against

airborne viruses and bacteria. (30) UVC LIGHT WAND DEVICES (31, 32)

UV based solution for PATH 3 airborne particles are discussed in additional detail later. For surface disinfection, newer handheld devices are becoming widely available. Housekeeping staff in hotels can use these devices for high touch areas in guest rooms, and restaurant staff can utilize them to sanitize tables and menus between customers. The benefits and concerns with this UV surface treatment are shown as below.

Figure 17. Far-UVC Applications (31)

BENEFITS

• Continuous disinfecting • Complete and uniform surface coverage • No training required • Safe for food service • Able to make limited claims against COVID-19

CONCERNS

• Lacking information about the components of the product and how it creates DHP • Limited number of sizes • May need many units depending on the area that needs to be covered • Could be expensive

BI-POLAR IONIZATION Ions are present naturally in the air. They are found in the highest concentrations where the ocean meets the shore and high elevation in the mountains. The bi-polar ionization (BPI) process artificially creates the ions found in these desirable locations and supplies them into the building, enhancing the indoor air quality. • Waterfalls/Elevation – 5,000 ions/cc • City – 200 ions/cc • Inside Buildings – <100 ions/cc
