About this trial
The goal of this randomized clinical trial is to test the efficacy of high efficiency particulate air (HEPA) cleaners in reducing respiratory viral exposure and infections in elementary school classrooms. Classrooms will be randomized to active vs. sham HEPA cleaners. The main questions it aims to answer are:
* Do classroom HEPA cleaners reduce exposure to viruses? * Do classroom HEPA cleaners reduce student and teacher infections? * Do classroom HEPA cleaners reduce infections in family members?
