Designing Built HVAC Filtration Systems for Optimum Performance

In this episode, Kevin Delahunt presents his insights on HVAC design and maintenance, going beyond filter performance to explore reducing particulate load in occupied spaces, the importance of filter hardware, designing for extraordinaryevents, and more. Listeners will gain a comprehensive understanding of how to design and maintain HVAC filtration systems that not only meet current standards but also ensure the health and safety of building occupants.

Practical insights and case studies will provide actionable steps for immediate implementation in their own projects.

[2:43] Kevin says there is an opportunity going forward to build messaging targeted toward engineers, designers, and other industry experts.

[3:52] One of the biggest problems facing the facility management industry is the “pandemic effect” – there is still a high vacancy rate in many facilities. As people return to the office, they have questions about how safe the air they’re breathing is.

[6:16] How did we get to MERV 13? To reduce the spread of infectious disease, ASHRAE suggests mechanical filterefficiency should be MERV 13 or higher.

[9:49] The pandemic has emphasized hardware issues. Filter hardware has not kept pace with filter technology.Additionally, physical units lack space to upgrade to better filters.

[16:40] If it doesn’t fit, it doesn’t filter. 100% of the air needs to go through the filter for it to perform effectively.

[17:50] There are 130,000 K-12 schools in North America, with an average age of 50. Each of these schools has an averageof 10 HVAC systems. 40% of those systems need to be replaced immediately.

[20:30] In 2023, 15 million hectares were burnt in the Canada wildfires – about the size of Illinois. Filtration professionals could upgrade filters during wildfire season to account for this.

[24:00] Commercial buildings collect data on air quality, but do not share that data. Kevin says that sharing air quality data could give businesses a competitive advantage.
