Indoor airPLUS Version 2

Indoor airPLUS Version 2, Certification and Gold Specifications

In February 2023, 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. These program updates supersede the draft updates released in December 2020, and are informed by public comment received on the 2020 proposal. Additionally, EPA is proposing changes to the training requirements for verifiers, and a Home Certification Organization model to improve quality assurance, as well as a 5-year expiration date to the new Indoor airPLUS labels with voluntary recertification by the home/building owner. See the Executive Summary documents below, along with the draft National Program Requirements and Certification System, for additional information.

Please see this recorded presentation for an overview of Indoor airPLUS Version 2, and a walkthrough of this webpage

Under the proposed Indoor airPLUS Version 2:

The new “Indoor airPLUS Certification” specifications focus on fundamental strategies to improve indoor air quality without a pre-requisite of ENERGY STAR certification.

Indoor airPLUS Gold Logo

The new “Indoor airPLUS Gold” specifications include more advanced protections for improved indoor air quality in conjunction with ENERGY STAR certification as a prerequisite.
