Protect your people and reduce sick days with safer air

Affordable assessments and step-by-step plans for safer indoor air.

Easy solutions for infection control and ASHRAE compliance

Better indoor air quality is key to preventing flu, COVID-19, asthma, and other health concerns. Building on our innovative health diagnostics, Primary.Health offers customized, affordable indoor air assessment and mitigation for schools, congregate living facilities, and public health domains. 

Our four-step air safety program makes it easy to broaden infection control and plan for new ASHRAE* building codes:

  • Assess: Breathing level air flow assessment with certified EOA (Equivalent Outside Air) scores based on latest ASHRAE standards.
  • Respond: Short- and long-term plans for improving air safety, including HVAC and non-HVAC solutions.
  • Empower: Data and resources to educate and empower building staff and facilities managers so that policy changes deliver outcomes.
  • Report: Single command center and regular trend reports to drive decision-making and monitor progress.


*ASHRAE is a heating, refrigerating, and air-conditioning standards body. Primary.Health is a non-voting member of its education committee.


Tailored air safety approaches

With fewer infection control mandates, administrators need new ways to keep locations safe. Primary.Health’s team has performed hundreds of indoor air assessments and can design a program that delivers short-term results with your existing infrastructure.

  • SchoolsCurb absenteeism from asthma, wildfires, allergies, and viruses through improved air safety and keep the community safe and healthy.

How it works

At Primary, we understand every organization faces unique administrative and health challenges. Our simple, affordable four-step approach can quickly improve air safety for healthier living, learning, and working.
step 1 icon


We assess air safety in rooms at breathing level and provide certified air change rate per hour (eACH) score for each room along with the new standard EOA (Equivalent Outdoor Air).

step 2 icon


We suggest short-term fixes like the proper use of air purifiers along with longer term strategies to increase air intake and adjust HVAC systems.

step 3 icon


Success requires a complete program including the education your building staff and facility managers need to make changes, focus resources, prioritize improvements, and spend responsibly.

step 4 icon


We can integrate our data into your dashboard and data management system. We can also provide custom notifications for facilities, teachers, and staff during higher risk times of year.
