Every review, in one place
Everything in the catalogue, grouped by what it actually is. Formats are not interchangeable, so they are not ranked against each other.
Every product we cover, with its published output, price, and whether we own it. Formats sit in separate groups on purpose: a tablet producing 12 ppm in a glass and a countertop machine producing 1.6 mg/L all day are not competing for the same job, and ranking them together would tell you the tablet wins when it does not.

Why some products have no review page
A product appears here once we have a price or a published output figure for it. It gets its own review page only once we can also name two genuine drawbacks - the build refuses to publish a review without them, which is deliberate. Anything listed without a review link is catalogued but not yet written up.
