How to Use Ventilation and Air Filtration For Schools

Air Filtration For Schools

School districts are often concerned with the air quality in their buildings. However, there is no national requirement for healthy and clean air in schools. A study by the Government Accountability Office (GAO) found that tens of thousands of schools had HVAC issues. Fortunately, COVID-19 has made it easier for schools to address these issues. There are several ways to maximize air flow in schools. Here are some tips for school leaders:

The first step in maintaining a healthy environment is to ensure adequate ventilation. Proper ventilation can help reduce the risk of spreading airborne viruses and bacteria. Insufficient ventilation is a common problem in school buildings. Older and newer buildings rarely have adequate ventilation. This means that students, teachers, and other school employees could be exposed to viruses and other diseases. To prevent these conditions, school facilities personnel should install pressure differential gauges near the air handling unit.

Another step is to install adequate outdoor air. A mechanical outside air system should supply 15 cubic feet per minute of outside air for each classroom occupant. A typical classroom with 30 people needs 45 cfm of outside oxygen. This means that the system should be able to provide adequate ventilation even when the temperature is very hot or cold. A properly installed air filtration system can prevent illnesses like influenza, pneumonia, and coronavirus.

In addition to air filtration, schools should also have an ionizer for students’ comfort. An ionizer emits negative and positive ions, which clump particles and make them easier to filter. These machines can also reduce the presence of viral particles in the air. Among the experts, Justin Klabin, a building developer who has a background in indoor air quality and whose sons attend school, has written a book on the topic. He has worked for many hours compiling scientific evidence and organizing petitions signed by dozens of parents in his school district.

One of the best ways to improve air quality in schools is to install portable air cleaners. These devices should be placed at opposite ends of the room to ensure that everyone can benefit from them. Moreover, the portable units should be of the correct size for the space in which they will be used. When properly installed, they will allow for better ventilation and air quality in the school. This way, schools can reduce the risk of allergic reactions.

While the use of air purifiers is important, the most cost-effective way to improve the air quality of a school is to install a window or two. This increases the number of air changes in a room and will also improve the temperature. Keeping windows open is the simplest, cheapest and most effective way to improve air quality. Nevertheless, experts disagree over the need for individual air purifiers.
