What happens when the underfloor air plenum area gets dirty?
Prior to installation of the flooring system, the concrete pad should be cleaned and sealed. By the time the flooring is installed, most of the dust creating construction work should be completed. Little dirt should get into the plenum area after construction. If material does get into the plenum, it can be vacuumed out. If debris gets into the MIT unit, it can be wiped out with a damp cloth, or cleaned out with a vacuum cleaner.
