Leveraging Plug Load Power Loggers in Air Cleaning Intervention Research

Learn how to Quantify the Clean Air Delivery Rate (CADR) of Portable Air Cleaners (PACs)

Accurately evaluating indoor air cleaning interventions requires more than simple on/off measurements; It demands detailed insight into how devices actually operate in real-world environments.

The experts in this HOBO Thought Leader webinar explore and explain how operational plug load monitoring can enhance the interpretation of indoor air quality (IAQ) data across a range of intervention studies. This session draws on recent field experience from three real-world settings: homes of U.S. military veterans in Chicago, K–12 schools across Illinois, and California homes using evaporative coolers during wildfire smoke events.

IAQ Monitoring Webinar Topics:

  • How plug load data loggers installed on portable air cleaners (PACs) can be used to quantify the amount of clean air delivered over time, including in-situ clean air delivery rate (CADR)
  • How PAC operational patterns vary among study participants in both residential and school environments
  • How combining detailed PAC operational data with time-resolved IAQ measurements provides deeper insights than binary on/off data or no operational data at all
  • How plug load data from both PACs and HVAC systems such as evaporative coolers (ECs) can be used to conditionally analyze indoor and outdoor particulate matter (PM) concentrations
  • How this combined approach can be applied to evaluate the effectiveness of a temporary DIY filtration solution for ECs for mitigating fine particulate matter infiltration from wildfire smoke

This webinar is ideal for researchers, building scientists, and IAQ professionals seeking to strengthen real-world intervention studies with more nuanced operational data and improved interpretation of indoor particulate matter measurements.
