Air Movement is Important
A key factor for choosing a dehumidifier is the amount of air movement needed to distribute dry air throughout the entire crawlspace or basement.
Conventional units recirculate immediately surrounding air to create a zone of warm, lower RH% air. This leads to short cycling of the dehumidifier, inefficient operation and poor moisture removal.
Air movement breaks down boundary layers at surfaces, promotes air mixing, reduces stagnant micro-environments, and help convect heat energy to the structural components you want to protect.
