Plastic-free living — the exposure science + the practical swaps

If you're new to the topic, three swaps deliver most of the practical benefit and don't require restructuring your life: switch from polypropylene baby bottles or daily plastic water bottles to glass/stainless; stop microwaving food in plastic containers (transfer to glass first); and replace non-stick PFAS-coated cookware. Per Cox et al. 2019 in Environmental Science & Technology, bottled water alone adds approximately 90,000 plastic particles per year to ingestion vs filtered tap. That single swap is the highest-impact starting point. The starter-kit and complete-guide pages below sequence the next steps.

The kitchen is where the most plastic-to-food contact happens daily. Heated plastic (microwave reheating, hot liquids in plastic cups, plastic-coated paper coffee cups) is the highest-shedding scenario per Li et al. 2020 in Nature Food. Food storage in glass instead of plastic is the easiest baseline change; non-stick cookware (PFAS/PTFE coated) replacement is the higher-cost but higher-impact upgrade. The pages below cover each kitchen sub-system honestly.

Water is the largest single ingestion pathway for microplastics (Cox 2019). Bottled water vs filtered tap is the biggest delta the published literature identified — Mason et al. 2018 in Frontiers in Chemistry quantified microplastic loads across 11 popular bottled water brands and found significant contamination across the category. The honest version of this swap is filtered water in glass, stainless, or borosilicate drinkware — not just "any reusable bottle" since some plastic reusables shed nearly as much.

The bathroom has surprisingly high plastic-touch frequency that's easy to underestimate — toothbrush, shampoo bottle, conditioner, body wash, deodorant, razor handle, period products, lotion. Many of these contact heated water (steam-shower environment increases shedding from plastic packaging) or contact mucous membranes directly. The pages below cover the full bathroom + personal care swap sequence + the period-products specifically (which have particular exposure concerns).

Infant exposure is the population subgroup with the strongest precautionary case for plastic-free choices. Li et al. 2020 documented that polypropylene baby bottles release significantly elevated microplastic loads during typical formula preparation (especially with hot water). Toys that are sucked or chewed for hours daily compound exposure. The pages below cover the baby registry rebuild, bottle alternatives, and the broader kids/toy materials question.

The remaining categories cover lower-frequency-contact items that still add up: bedroom textiles (mattresses, pillows, bedding all increasingly contain synthetic plastic-derived fibers); cleaning products in plastic spray bottles + plastic-derived surfactants; office supplies; outdoor and gym gear. Each room of the house has its own version of the same materials question.

A few cases warrant separate treatment: reef-safe sunscreens cover both the personal-skincare angle and the broader marine microplastic concern (oxybenzone in chemical sunscreens contributes to coral bleaching and microplastic load); fertility-safe products specifically address endocrine-disruptor exposure during pre-conception and gestation; and the Netflix Plastic Detox documentary checklist is the curated entry point for users who arrived here from the show.
