FUNDING POLICY

Independence is
the point.

Rankings and verdicts are never for sale.

Current funding

This edition has no advertising placements, paid product listings or affiliate buy buttons. External links are provided as research sources.

If that changes

Any affiliate relationship will be disclosed clearly beside the relevant links. A commercial relationship must never change a verdict, obscure evidence gaps or turn an unverified claim into a recommendation.

Off limits

Filter Math does not accept paid rankings, sponsored reviews or undisclosed product placement. Reader trust comes before revenue.
