Everything sheds — wool, cotton, polyester, polypropylene. The difference is not whether fibres enter the lung but whether the lung can process what it has inhaled. The body has enzymatic clearance pathways for cellulose and keratin. It has no pathway for polyethylene, polypropylene, or polyethylene terephthalate.
In this episode, we debate: Is the failure of indoor air quality to mobilise consumer behaviour fundamentally a story-shape problem — the risk cannot acquire the narrative elements needed to travel — or a psychological feature of the home itself, where the Safe-Room Override makes risks feel safe by structural definition?

This is the final episode in The Indoor Air Problem series. Episode one (The Dominant Route) established how instruments shape what we notice. Episode two (The Unregulated Room) mapped the regulatory void. This episode turns inward: why we struggle to act on this risk even when we know about it.
