694. You’re Breathing This Every Day (And Most Homes Get It Wrong)
·7 min
The episode begins by challenging the common belief that a home's temperature control equates to overall comfort, highlighting that HVAC systems circulate air containing dust, pollen, and other particles. Derek Cole introduces IEQ (indoor air quality) as a critical but often overlooked aspect, noting that allergies and stuffiness can signal issues. He reveals that even new systems don't fix air quality, as they primarily manage heat. Cole then details three IEQ pillars: filtration, where he recommends MERV8 filters as a balanced choice; air purification, advocating for whole-home systems over room-based ones; and humidity control, explaining its dual role in summer and winter. He uses analogies, like humidity being a blanket, to simplify concepts. In the latter part, Cole offers practical steps: changing filters regularly, checking airflow, and assessing individual home needs like pets or allergies. He stresses customization, as homes with wet crawl spaces or humidity problems require different solutions. The episode wraps with a memorable phrase—'be a filter or buy a filter'—urging listeners to act preemptively on air quality.
