Episode Details

That funky smell when you blast the AC isn't just unpleasant — it's a biohazard. From "sick car syndrome" to home HVAC "dirty sock syndrome," this episode breaks down the shared physics behind moldy filters, the health risks of breathing microbial VOCs and mycotoxins, and exactly how often to change your cabin and home air filters. Learn the difference between a $15 DIY fix and a $3,200 coil replacement, why a MERV 13 filter might wreck your old blower motor, and how one pediatrician diagnosed a car maintenance problem in his exam room.
