Methodology

How we score

Every product on lapomio carries a Spec score from 0 to 10. It is calculated from listing specifications, not lab tests — and this page publishes the whole calculation, so you can re-run it yourself.

The rules

  • Specifications only. Pack sizes, durations, doses, formulas and formats — the facts printed in the product's listing and the brand's own specifications.
  • No prices, ever. Price is not a criterion and is never printed on this site; it changes too often to score honestly.
  • Brand statements are marked. Anything a brand says about its own product ("99.9% dust free") enters the score as a brand claim and is labeled as one wherever it appears.
  • Scores compare inside a category. A litter and a collar answer different questions; their criteria and weights are different tables.
  • Not hands-on tests. We have not tested these products in person. Reviews are research-based and say so on every page.

Why publish all this?

Because a score you cannot check is just an opinion with a number glued on. If you weight the criteria differently — say, dust matters twice as much to you — the tables above let you recompute any score in a minute and pick differently. That is the point.
