Indoor AirPlus Version 2 Development
In February 2023, the EPA proposed updates to the Indoor AirPlus program including a two-tiered certification program and other changes to strengthen and update program specifications and requirements. Additionally, the EPA proposed changes to the training requirements for partners, and a Home Certification Organization model to improve quality assurance. The public comment period is now closed. Thank you to those who reviewed and provided input.
The final Indoor AirPlus Version 2 Certification Protocol, National Program Requirements, Verification Requirements, and supporting resources can be found on the Program Documents webpage. The EPA will be making additional revisions to the proposed IAP V2 Certification System and HCO Application for Recognition, anticipated for release in late 2024.
