2018 HPC National Conference Session
High MERV filters installed in air handlers with sufficient run-time can provide significant filtration, removing fine particles from the home's air. However, this filtration may come with significant costs, both in fan and building energy costs and HVAC system performance. This session will provide an overview of particles and human health, and filter performance. Explore lessons learned to date from the ROCIS Air Handler/High MERV filter Inquiry (http://ROCIS.org) Air handler systems have been tested to determine the watt-draw, optimal blower speeds, air flow, and total external static pressure to determine whether or not they could be used with a high MERV filter to affordably reduce household particle levels. Retrofit options will be described, as well as the performance (air flow, blower energy cost and particle reduction (0.5+ microns)) achieved. The challenge of replacing PSC motors with ECMs and filter replacement and cost will also be discussed.
Linda M. Wigington & Associates
Linda Wigington is the founder of and has been associated with the Affordable Comfort Conference from its inception in 1986 until 2013. These regional and national events have been instrumental in building the capacity to deliver a whole house approach which addresses the integration of health, safety, durability, and energy performance. Recently, Linda has served as the team leader for the Reducing Outdoor Contaminants in Indoor Spaces (ROCIS) initiative which is funded by The Heinz Endowments (http://ROCIS.org). The goal is to empower champions who work within housing, energy efficiency, environmental advocacy, healthy schools, sustainability, and health-related sectors with the outcome of enhanced collaboration and initiatives to protect indoor spaces and their occupants from outdoor pollution. The ROCIS Low Cost Monitoring Project began in fall of 2015.
