Making the case for clean classroom air

Consistently and actively cleaning school air benefits include:

  • Mitigating infectious contagions
  • Supporting cognitive performance
  • Improving learning outcomes
  • Minimizing student absences
  • Reducing substitute teacher days

Monitoring and improving indoor air quality throughout campus can be affordable and effective. However, most professionals in air handling are not aware of the latest research, guidelines, techniques, or equipment. These are not complicated or arcane, but essential all the same.

We know how to come back to the classroom safely and responsibly.

You Make the Difference

The difference between successful school openings and more disruption to teaching and learning (chaotic closures and quarantines) can be fast, simple, and painless. The equipment is available, the rollout is straightforward, and the monitoring is transparently informative.

The Simple Science

The keys to clean, healthy air are straightforward. We want to bring in fresh outdoor air, filter all the air and create airflows that mix and dilute any concentrations of pollutants. Each of these processes are well understood and excellent equipment options exist.

The key to consistently clean and healthy air, however, is monitoring! First, you cannot improve what you don’t measure. Proper monitoring of air quality sets baselines for system design and performance characteristics. After deployment, continuous monitoring assures that equipment is functioning, maintenance is appropriate, and any miscellaneous problems are resolved quickly.

It all starts with monitoring. You wouldn’t drive a car without a speedometer, so why breath air you know nothing about?

It's Easier Than You Think

Six effective air changes per hour (eACH) is the benchmark for clean air

you don't know if you don't verify

It starts with increasing the amount of outdoor, filtered air into the system, then adding a robust network of HEPA filters to clean and mix the air within the space. Monitoring is essential to validating and insuring the system is doing its job of reducing risk in the classroom.

The cost to implement clean air is around the cost of a textbook per student.

Best Practices to Get Started

The CDC and ASHRAE agree on the key guideline for air handling and purification. For minimizing the probability of pathogen transmission in congregate environments (like schools), the recommendations indicate a minimum of six efficient air changes per hour (or “6 eACH”, in the parlance).
