Posted on Thu, Oct 04, 2018


At UltimateAir, we’re dedicated to providing our customers with the best in ventilation systems, ensuring the air in their homes or places of business is clean, fresh, and allergen free. And whether you’re installing one of our energy recovery ventilation systems in your residence or workplace, you’ll be glad to know that our units are compliant with ASHRAE standards.

Let’s take a moment to look at some key details about ASHRAE, including what the association oversees, what their standards denote, how equipment fulfills ASHRAE ventilation requirements, and more.


ASHRAE stands for the American Society of Heating, Refrigerating and Air-Conditioning Engineers. This global association is dedicated to advancing the HVAC field by providing research opportunities, education programs, and technical standards for businesses within the sector. 

ASHRAE was formed in 1894 and over the years it has grown to a membership of more than 50,000 representatives within various industries, including building owners, equipment manufacturers, mechanical contractors, architects, engineers, and more.

Some key details about ASHRAE:

  • The organization has gone under various monikers to keep up with the technology of the time. Previous names include the American Society of Heating and Ventilating Engineers (ASHVE), the American Society of Heating and Air-Conditioning Engineers (ASHAE), and the American Society of Refrigerating Engineers (ASRE)
  • Though the association has “American” in its name, and was originally formed in New York City, it has a global focus with international events being sponsored throughout the year
  • Along with their print magazines, the ASHRAE Journal and High Performing Buildings Magazine, ASHRAE provides a thorough online standards review database. All of these resources help those in the industry stay up to date with changes and developments happening in HVAC
  • Additionally, ASHRAE supplies a four-volume resource for businesses called the ASHRAE Handbook, touching upon key topics in the HVAC field. Each year, ASHRAE updates one of the four volumes on a rotating basis

Of course, one of the core aspects of ASHRAE is their standard designations for the industry. These standards include criteria for refrigerant safety, heating conditions for occupancy levels, energy standards, data communication protocols, designs for high performance, and indoor air quality standards.

Their indoor air quality standards are the most relevant to UltimateAir, as we design our systems to be ASHRAE ventilation standard compliant.

ASHRAE Indoor Air Quality Standards

ASHRAE provides two standards for indoor air quality, ASHRAE 62.1 and ASHRAE 62.2. These standards are categorized as Ventilation for Acceptable Indoor Air Quality (ASHRAE 62.1) and Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings (ASHRAE 62.2). Let’s take a look at aspects of each and what they mean for indoor air quality, or IAQ.


  • The purpose of this standard is to specify minimum ventilation rates and other measures intended to provide indoor air quality that is acceptable to human occupants and minimize adverse health effects
  • This standard is designed for the regulation of new buildings, additions to existing buildings, and changes to existing buildings
  • It applies to spaces intended for human occupancy except for within dwelling units in residential occupancies with nontransient residents, and does not cover single-family dwellings
  • Adequate ventilation is determined by ventilation rate, IAQ, and natural ventilation


  • This standard applies to dwelling units in residential occupancies in which occupants are nontransient, which includes single-family homes
  • Chemical, physical, and biological contaminants that can affect air quality are taken into consideration as part of the standard
  • Adequate ventilation is determined by ventilation rate, IAQ, and natural ventilation. Because of this standard’s focus on residential units, its requirements are more rigorous

Our air ventilation systems at UltimateAir exceed ASHRAE 62.2 ventilation recommendations, ensuring clean, fresh air for your home or business.

UltimateAir’s Home Ventilation Systems

Our whole house ventilation systems, which feature up to 99% energy recovery, have been designed to meet ASHRAE ventilation standards. Our systems are held to ASHRAE’s MERV rating standard.

MERV stands for the Minimum Efficiency Reporting Value and denotes the effectiveness of air filtration systems. ASHRAE’s rating system through MERV is listed on a scale of 1-16, with the higher the number, the greater the percentage of hazardous materials being captured.

MERV ratings for residences should be at a minimum of 6, as designated by ASHRAE. Commercial buildings and industrial workspaces, meanwhile, often utilize systems that hold ratings of 5-8.

Our RecoupAerator® units have been rated at a MERV 12, well above the minimum required for residences. As the EPA has stated, a score of 12 usually applies to “Superior Residential” units and “Hospital Laboratories.” Additionally, our systems trap virtually all mold spores and pollen, helping to significantly reduce the risk of allergens.

Our available home ventilation systems include:

  • 200DX ERV RecoupAerator® – Our 200DX system features a variable speed flow range of 30-200 CFM, which makes this unit ideal for residential and small commercial buildings in the range of 700-4,500 square feet. The unit’s Heating Recovery Efficiency (ASE) is rated up to 98%, while its Cooling Recovery Efficiency (TRE) is rated up to 53%.
  • ER80M ERV RecoupAerator® – Our ER80M system features a variable flow range of 20-100 CFM, ideal for living spaces with 1,500 square feet or less. The unit’s heating Recovery Efficiency (ASE) is rated up to 99%, while its Cooling Recovery Efficiency (TRE) is rated up to 45%.

We also have the capability to provide lite commercial energy recovery ventilation systems. Check out our commercial page for details.
