Our Review Methodology

Every filter we review is tested in real pool conditions for at least one season. We measure actual pressure readings, flow rates, and water clarity. For products we cannot test ourselves, we conduct structured research across verified buyer reviews, manufacturer specs, and third-party lab data, and we say so clearly in the article.
