Dyson Begs Feds: Fix Air Cleaner Room Size Tests Now!

## Summary

Dyson asked the Department of Energy to change how air cleaners’ room size and energy use are tested and shown to customers. Right now, DOE isn’t making any changes but wants to hear what people think before deciding. If you have ideas or info, you can share them by May 30, 2025, so this could affect air cleaner makers and buyers soon.

## Abstract

On September 11, 2024, the Department of Energy ("DOE") received a petition from Dyson Inc. for DOE to revoke the procedures by which manufacturers must measure and represent to consumers the effective room size coverage and integrated energy factor of their air cleaner products. If the provisions are not revoked, Dyson Inc. requested that DOE stay enforcement of these provisions pending a new notice and comment period regarding potential amendments to these provisions. DOE is not revoking or staying enforcement of the test procedure and representations provisions raised in Dyson's petition at this time. Through this notification, DOE is seeking views on whether it should grant the petition and undertake a rulemaking to consider the proposal contained in the petition, as well as any data or information that could be used in DOE's determination whether to grant the petition.

## Effects PRIA read

- Rule forces room-size claims using 1.55× smoke CADR: cost, medium. Federal rules (10 CFR 429.68(a)(4)) require manufacturers to represent an air cleaner's effective room size by calculating the product of 1.55 and the product's smoke CADR. This requirement was implemented in DOE's air cleaners test procedure final rule published March 6, 2023 (effective December 3…
- Energy (IEF) must be measured by appendix FF test: cost, medium. Federal regulations (10 CFR 430.23(hh)(4)) require conventional room air cleaners' annual energy consumption and integrated energy factor (IEF) to be measured using section 7 of appendix FF to 10 CFR part 430, subpart B. DOE incorporated that test procedure in its March 6, 2023 final rule (effectiv…
- FTC proposed using DOE rule on EnergyGuide labels: cost, low. The Federal Trade Commission proposed on February 2, 2024 (89 FR 7566) to add room-size coverage claims to required EnergyGuide labels and to require those numbers be calculated using the DOE/Room Size Coverage methodology. The petition warns that FTC adoption could magnify harms, and could impose…
- DOE keeps rules in force; invites comments by May 30, 2025: mixed, low. DOE is not revoking or staying enforcement of the cited test-procedure and representation provisions raised in Dyson's petition at this time. DOE is requesting public comments and information on whether it should grant Dyson's petition; written comments will be accepted on or before May 30, 2025 (d…
