Panel 1: How Do We Achieve Better Indoor Air Quality (IAQ)?

An in-depth discussion of:

  • Standards/regulations like MERV 13
  • Acceleration of IoT monitoring and "smart" technologies
  • Room air cleaning/antimicrobial treatments
  • Strategies for IAQ in nonindustrial environments

Tuesday, March 29
1:30 pm - 3:00 pm

Josh Ayer, President & COO, Hollingsworth & Vose Company

What to Expect

There is expanding appreciation and awareness from consumers about the importance of air and water quality in all aspects of modern life. Particular to Indoor Air Quality, we are seeing consumer demand, governmental regulations and corporate standards that are accelerating demand for advanced filtration systems. This in turn is pushing innovation in filtration solutions. As MERV13, and even HEPA levels of filtration increasingly become associated with long-term health, growth will continue for filtration in public buildings, private homes, vehicle cabins and beyond. Our industry is at the forefront of developing new filtration solutions that provide better air quality with lower energy consumption.”
