This is what we use on individual rooms in a house as opposed to
in a very large teaching area (36 x 48 = 1728 sq ft; a |
|
typical school would be 48 x 55 overall with discrete spaces for
lockers, office, bathrooms, kitchen ...) |
|
The device above is a Medify Air MA-14-W. It has an H13 HEPA
filter, which is an upgrade on a so-called 'true' HEPA: |
|
both are supposed to remove particles 10 microns or larger of
pollen, dust, mold, bacteria, dustmites, common smoke (a |
|
concern these days in California), lead dust and pet dander. H13
also is supposed to filter smaller particles of asbestos, |
|
insecticide, tobacco smoke and so on down to particles 0.1
microns in size. This device has a CADR of 120 which means it |
|
should clean the air in a 200 square foot room in 30 minutes and
the air in a 470 square foot room in 60 minutes. |
|
The device was about $100 and the replacement air filter is
about $40. |
