Bottled water marketing is genius. The product is mostly tap water in a plastic bottle that leaches microplastics into what you drink. Filtered tap beats it on quality, cost and environment — every metric.

A family of four buying bottled water spends $1,800–$2,400/year. The water inside is often filtered municipal supply — the same source as your tap, in plastic that's leaching microplastics into every sip.

What's actually in bottled water

  • 240,000 plastic particles per litre (Columbia University, 2024)
  • BPA and phthalates from the bottle itself
  • No PFAS regulation in Australia for bottled water
