Query: works well for small areas...not so much for large ones

we got these to dehumidify our master bedroom closet (about 4ft by 9ft) because there is some dampness under the house. they work well and remove moisture but we're constantly recharging them every week or so that we now rotate 5 of them into the closet all the time. while they are a great product, their niche is aimed at smaller areas.
