Yesterday I posted about a/c and how humidity is such a burden for the unit. Today we shall learn about homemade dehumidifiers, a concept I had never thought of until Ruben googled it last night. A timely topic for the humid month of August.

In my five minute research into the topic, there appear to be two basic kinds of homemade dehumidifiers: one uses charcoal and coffee cans with holes poked in the lids and the other employs road salt (calcium chloride), cheesecloth, and plastic buckets. Since the second kind requires more things I don’t have, and probably a trip to a store I don’t normally go to, I think I’ll begin my own experiments with charcoal. An additional advantage to charcoal is that it is also a natural deodorizer. See further ways you can implement the dehumidifying/deodorizing properties of charcoal here.

The charcoal version is very simple: just put some charcoal in a container that has holes poked in the lid and place containers around areas that need dehumidifying.

The road salt version is a bit more obtrusive: you dump some road salt in cheesecloth, tie the cheesecloth off, hang it up somewhere, and put a bucket underneath for the moisture to drip into. No doubt Laura or anyone could incorporate this into home decor as ‘modern slaughterhouse’. “We wanted to create the homey illusion of slabs of raw meat hanging from the ceiling”. This is supposed to be very effective and gets rave reviews from the kind of people who know what ‘road salt’ is to begin with.

(Incidentally, someone mentioned putting the salt in a colander over a bucket — and he used a different kind of salt, rock salt I think — but he didn’t say how that worked out. However it’s a possible alternative to having to hang something.)
