An independent, test-first alternative to the sales pitch.
Know Your Tox exists because most people find out what's in their water, their air, or their everyday products from whoever's trying to sell them something about it. We think that's backwards.
We're an independent testing and consultation company — not a manufacturer, and not a dealer for one. We don't make money by pushing a specific brand of filter or system, because we don't sell any brand exclusively. Our only job is to tell you, plainly and honestly, what a real test actually found — and then help you decide what, if anything, is worth doing about it.
We started with water, because it's one of the most under-recognized and most fixable sources of everyday exposure most households never think to check. It won't be the only thing we cover — but we'd rather do one thing well and expand deliberately than launch everywhere at once and do all of it poorly.
Three rules we hold ourselves to.
We cite real data, not fear
Every claim we make traces back to EPA, EWG, or another public, checkable source — never an invented statistic or a scare tactic.
We're brand-agnostic
We're not paid by any manufacturer. What we recommend is based on your results, not a sales quota or a commission structure.
Cost isn't a gatekeeper
Sliding-scale testing exists so a family's income is never the reason they go without knowing what's in their water.
