PECO technology by Molekule—Destroys Covid-19 virus & more.

*Molekule’s PECO technology captured & destroyed over 99% of the Covid-19 virus in laboratory tests. Real-world results may be less. No air purifier can prevent virus transmission. They are not substitutes for ventilation, PPE, vaccines or social distancing.

Science at the nanoscale

Developed over 25 years by research scientists, PECO is an innovative technology that utilizes free radicals—the same radicals used to destroy cancer cells—to break down pollutants at a molecular level, including VOCs, bacteria, mold, viruses, and allergens. By using nanotechnology, PECO is able to destroy pollutants 1000 times smaller than the standard filters must meet to qualify as HEPA.

Under the microscope

PECO destroys pollutants at a microscopic scale, including chemicals 1000x smaller than what the HEPA filter standard tests for. With no ozone byproduct, Molekule air purifiers safely destroy a vast range of indoor air pollutants. As a science company, Molekule conducts extensive testing of its technology through its own labs as well as certified third-party laboratories.

White papers & technology reports

Molekule believes in scientific disclosure. That’s why we make our testing and scientific data public.

  • VOC Destruction Report

    As tested by Intertek, a nationally recognized testing laboratory (NRTL), Molekule’s PECO technology destroys VOCs without re-release, unlike any other technology available. Download

  • Ozone Emission Test Report

    Scientific testing by Intertek and the University of Minnesota Particle Calibration Laboratory shows that Molekule’s PECO Technology doesn’t produce ozone as a byproduct and actually reduces it in the air. Download
