What is Indoor airPLUS?

Indoor airPLUS is a voluntary partnership and labeling program that helps new home builders improve the quality of indoor air by requiring construction practices and product specifications that minimize exposure to airborne pollutants and contaminants.  Clean air is good for everyone’s health, but it can be especially important to those who have chronic respiratory conditions.

EPA created Indoor airPLUS to help builders meet the growing consumer preference for homes with improved indoor air quality. Indoor airPLUS builds on the foundation of EPA's ENERGY STAR requirements for new homes and provides additional construction specifications to provide comprehensive indoor air quality protections in new homes.

Construction specifications include the careful selection and installation of:

  • moisture control systems
  • heating, ventilating and air-conditioning systems
  • combustion-venting systems
  • radon resistant construction
  • low-emitting building materials.

How Does a New Home Become Indoor airPLUS Qualified?

A builder must first design a home to earn the ENERGY STAR Certified Home label — the government-backed symbol for energy efficiency. The result is a home that is significantly more energy efficient than a home built to minimum code, helping reduce greenhouse gas emissions.

To earn the Indoor airPLUS label, the builder then adds additional home design and construction features to help protect qualified homes from moisture and mold, pests, combustion gases and other airborne pollutants. Before the home officially earns the Indoor airPLUS label, it is inspected by an independent third-party to ensure compliance with EPA’s rigorous guidelines and specifications.

What are the benefits to building an Indoor airPLUS home?

By constructing homes that meet EPA's Indoor airPLUS specifications, builders can distinguish themselves by being among the first recognized by EPA to offer homes designed to truly deliver better indoor air quality. Participating builders can expect higher levels of quality assurance, improved reputation, reduced callback and warranty costs and less business risk. Partners are also eligible to use Indoor airPLUS marketing materials and tools to help promote their qualified homes as well as access technical and marketing assistance.
