Air Purifiers in Classrooms for Infection Control

Status Active, not recruiting

Clinical Trial Summary

This study aims to investigate the acceptability and feasibility of deploying air purifiers equipped with HEPA (high-efficiency particulate air) filters in classrooms, to study air purifiers as an infection control measure. It will also evaluate the direct effect of air purifiers on air quality, comparing ceiling-mounted purifiers, portable purifiers and no purifier.

Clinical Trial Description

Improved ventilation and air purification have been proposed as promising measures to protect the health of students and children while avoiding future school closures during pandemics. However, there is limited knowledge regarding the effectiveness and potential drawbacks of using air purifiers in educational settings. This pilot study was initiated to explore whether a large study of air purifiers in Norwegian primary school classrooms is feasible and acceptable among teachers and students, and to uncover whether air purifiers can reduce particle density in classrooms and thus potentially decrease the spread of infections. The results will lay the groundwork for larger-scale trials that could form the basis of knowledge for decision-makers on whether the use of air purifiers should be part of the strategy to limit infections in classrooms while avoiding school closures during future pandemics. The pilot study consists of two parts. The first part will last six weeks, and focus on the feasibility and acceptability among teachers and students. It will describe and compare two arms - ceiling-mounted (arm 1) and portable (arm 2) air purifiers. The second part lasts nine weeks, and will evaluate the direct effect of air purifiers on air quality. It will compare ceiling-mounted, and portable devices and no purifier(arm 3). The study will involve multiple schools, with a total of six schools contributing eight classrooms. Arm 1 will have two schools and arm 2 will have three schools, each school contributing with one classroom. Arm 3 will have one school, contributing with three classrooms. The classrooms will preferably belong to 7th grade students, but 6th and 5th grade student classrooms will also be accepted, based on the schools preferences. Data collection includes interviews and questionnaires from teachers and students, observations, as well as absenteeism data and air quality measurements. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
