This study, called the School Inner City Air Study, is looking at whether portable HEPA (High Efficiency Particulate Air) cleaners can help reduce viral infections in elementary school classrooms. Researchers will place either an active classroom HEPA cleaner or a sham classroom HEPA cleaner (which looks the same but doesn't filter air) in classrooms. The main goal is to see if these cleaners reduce how many viruses are in the air and if they lower the number of infections in students, teachers, and their family members. We will measure if viral pathogens (germs that cause illness) are detected in upper respiratory samples after one year. Children aged 6-12 in grades K-5 who attend participating schools and adults aged 21 and older can join. The study is currently unclear on its recruitment status.

Study design

This is an interventional study where classrooms will be randomly assigned to receive either an active or sham HEPA cleaner. It plans to enroll 200 participants.

What's involved

Participants will have longitudinal (over time) classroom air samples and upper respiratory samples collected. They will also complete symptom surveys.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for one year, as viral pathogen detection in upper respiratory samples is measured at that time point.
