Verified to its source.
A filter spec is only useful if it is correct. One wrong dimension and the wrong part ships. So we label every specification with how confident we are in it, we tell you where it came from, and we never pretend a gap is a fact.
How we label confidence
Not every number deserves the same trust, so we don't display them all the same way. Each specification is tagged with one of three tiers.
The number on the page matches the manufacturer’s published engineering data or datasheet. When a specification carries this tier, we have seen it at its source. Dimensions shown this way are confirmed against original manufacturer documentation.
The value comes from a manufacturer or authorized distributor publication. It is traceable and reliable, and we label it so you always know where a number came from rather than presenting every figure as if it were identical in confidence.
A cross-reference is a fit-and-rating claim: the parts share dimensions that fit the same housing and a micron rating that is approximately equivalent. It is not a claim that two filters perform identically. Beta ratio, dirt-holding capacity, media chemistry, collapse strength, and service life can differ between brands, and we surface those differences rather than hide them.
Independent and brand-neutral
VerifiedFilters is independent, so our only job is helping you find the right filter for your application, whoever makes it. When two parts cross-reference each other, we show you both honestly, including the places where their specifications differ, so you can choose with the full picture in front of you.
A blank is not a guess
When we don't have a verified value, we leave it blank rather than fill it with a number we can't stand behind. A missing dimension is honest work still to be done, and every gap goes onto our list to be found and confirmed at its source. We would rather show you nothing than show you something wrong.
