FLOOR PLAN OF THE PROBLEM

Room Guides

Your house, ranked by threat level. Each guide lists the biggest sources in that room and a ladder of fixes: free first, cheap second, invest third.

Heat + knives + plastic is most of your controllable dose. One rule and four swaps fix the whole room.

Bottled water is your densest exposure source. Quitting it is free, filtering tap is a one-time fix, and the savings pay for the gear.

You wear plastic, and it sheds — into the water system and your indoor air. Washing habits are free; a filter catches the rest.

Lower stakes than the kitchen, but the swaps are cheap, permanent, and weirdly satisfying. Use up what you own, then never rebuy.

Highest dose per kilo in the house, concentrated in two fixable sources: hot prep in plastic bottles, and the floor they live on.

One good swap a week
