How we choose

We carefully select shower filters and everyday care from brands we believe deserve a place in your routine. Here is what that means in practice.

Every product ships from the United States

Each item leaves a US warehouse, run by the brand or by a US retailer that stocks it. You get tracking by email. GoodFor and Sentry filters and cartridges ship free; other items ship at the brand's own rate, shown before you pay.

We write from the brand's own information

Product pages use what the brand documents: what is included, how it fits, how to care for it and, for filters, which cartridge it takes and when to change it. If a brand has not shared a detail, the page says so. We do not fill gaps with guesses.

We list filtration claims only with a test report

Where a brand has published a laboratory test, we summarise it and say what kind of test it was. Where there is no report, we do not describe what the filter reduces.
