Testing Mobile Air Purifiers

The district plans to measure ozone levels in each classroom using a particle counter. That figure is below the federal standard for safe air for working adults, which is 100 parts per billion. However, this standard shouldn’t apply to developing children. “Ozone exposure levels should be lower than the amount found in a normal adult classroom,” says Michael Kleinman, an air-quality researcher at UC Irvine.

To determine whether a portable air purifier works in a classroom setting, researchers at the Harvard T.H. Chan School of Public Health devised a downloadable calculator. Using this tool, they measured the amount of time it takes for the air to filter the room. The best purifiers can provide continuous, low-noise ventilation for a classroom. Unlike portable air purifiers, these devices can also reduce the risk of respiratory infections like asthma, which are particularly common in schools.

To test the effectiveness of mobile air purifiers, researchers gathered data from three lessons using uCPCs. During the tests, the purifiers removed 99.97 percent of bacteria and viruses. During the experiment, they were installed in the classroom and the teachers reported that the filters were easy to install. They also complied with the guidelines of the New York City Department of Education.

The study also looked at the noise produced by air purifiers. Six teachers took the survey and found that the loud sound from the device did not disturb them. But, if you’re a teacher, the noise can affect your ability to teach. So, if you’re a teacher considering mobile air purifiers for your classroom, it’s essential to consider the noise generated by the device.

Testing Mobile Air Purifiers in a School Classroom

In addition to the classrooms, two nearby classrooms were also monitored for air pollution. They were the same as classroom B110, but no air purifiers were installed in them. The test rooms had uCPC and OPS monitors, but they were not monitored. Moreover, the students’ health was unaffected by the presence of the air purifiers in the classrooms.

When testing mobile air purifiers, it is important to consider the noise level. It should not be too loud to disrupt a classroom’s environment. But a noisy air purifier can be distracting for the students. The average noise level in a classroom is 49 decibels. This isn’t a problem in a school. The sound is so low that it can be completely ignored.

For the most effective air purifiers, the CADR should be as high as possible. This will decrease the number of particles in the air, which means that the device is a safe, effective solution. For example, the CADR should be as high as 980 if the machine was installed in a classroom with two identical sizes. At this level, the system is highly efficient, but the highest speed is not the best for an office.
