On September 11, 2024, the Department of Energy (DOE) received a petition from Dyson Inc. requesting the revocation of certain testing procedures for air cleaners. Dyson argues that the current methods for measuring room size coverage and energy efficiency are inaccurate and misleading to consumers, leading to energy wastage and stifled innovation. Dyson's petition suggests these rules should either be revoked or enforcement paused to allow for a review and possible amendments. The DOE is currently seeking public comments on whether to proceed with rulemaking based on Dyson's proposal.
Simple Explanation
DOE is checking if Dyson's claim is true that the way air purifiers are tested doesn't work well and might waste energy, so they might change the rules on how to measure their performance.
