Many Chinese makers now certify models to <a href=\"\/de\/ahri-1060-air-to-air-energy-recovery-rating\/\">AHRI&nbsp;1060<\/a> (air-to-air energy recovery) and AHRI&nbsp;410. If the model is not in the directory, the claim is unverified.<\/p>\n<h2>Eurovent<\/h2>\n<p><strong>eurovent-certification.com<\/strong> lists certified units with independently verified performance.
