Trego School’s Health and Safety Plan includes HEPA filters installed in air purifiers and in the heaters. While the filters for the heaters have not yet arrived (and are not expected to be needed soon, given current temperatures), the others are here.
HEPA filters specialize in filtering out the really small, things measured in microns (a micron, or micrometer, is a thousand times smaller than a millimeter). This means that they aren’t just going to pick up relatively large particles in the air such as dog hair.
These filters are effective at removing dust, pollen, and smoke particles from the air. This particular model will filter a 23 ft by 23 ft room in about 15 minutes.
The filters are plain, discrete, and nearly silent. The biggest risk seems to be that students and staff will wander over to the trashcan-like cylinder and have to redirect, a problem that should surely lessen with time.
While the immediate use of the filters is obvious, it will be interesting to see how well these filters help students with asthma, and allergies. Will they be pressed into service the next time our air is filled with smoke? Will we see less spread of other illnesses this year, as our schools check temperatures, wash hands, and spread out?
School starts on Wednesday, September 2nd. Enrollment information can be found on the school website.
