Technical Session 5 - New technologies addressing Pathogen Transmission and Odor Control

Charles Waddell

Friday, April 30 - 2:30 - 3:30 pm

The presentation will discuss pathogen transmission within a facility and how to reduce the probability of transmission. The method in which Needlepoint Bipolar Ionization (NPBI) reduces particles and also kills mold, bacteria and inactivates virus will be discussed.     

Learning Objectives:

  1. To become familiar with NPBI and understand where it’s been applied using references and case studies

  2. Understand how NPBI is being used as a replacement to carbon in many applications to control odors from helicopters, diesel generators, loading docks, etc. 

  3. Understand how NPBI is being used as a replacement to UVC for coil cleaning and pathogen control

  4. Understand how NPBI reduces particles, odors, pathogens, maintenance and energy

  5. Understand how the NPBI increases a MERV 8 filter to MERV 13 and a MERV 12 filter to MERV 16.
