@jill6063 That's an interesting question for December 30th - maybe you live somewhere warm?

Central air conditioning, if hooked into the ductwork system in your home is a better option because you can place filters in the ducts to help control dust and particulates in the house. Two caveats - the moisture removed must be directed outside or directly into a drain and the filters must be changed OFTEN - usually even more often than recommended - but filters can easily be bought in quantity to keep the price down and this is an easy do-it-yourself task.

Window air conditioners also have filters, but they are tiny by comparison and require attention as often as weekly during the cooling season.
