This week on This Old House Radio Hour, we’re talking about something you can’t see but definitely feel: the air inside your home. Kenneth Mendez, president of the Asthma and Allergy Foundation of America, shares the smartest, science-backed ways to improve indoor air quality—from high-heat laundry to HEPA vacuums—and explains why your bedroom might be the most important place to start.

Then, The Splendid Table’s Francis Lam takes us back to the New Jersey home of his childhood. With vivid stories of birthday parties, incense-filled kitchens, and Hardy Boys books read in a mirror-covered living room, Francis reflects on how homes carry our deepest identities and contradictions.

We also help callers tackle squeaky floors, stubborn drafts, mismatched temperatures, and that infamous 1970s gold bathtub. Plus, a fresh edition of House Rules and a real estate segment from Cheap Old Houses featuring a tiny Gothic summer cottage and a quirky Kansas gem for under $55,000.

All this, plus a “Simple Fix” from Tom Silva that will stop your window drafts cold.
