Something Christopher mentioned about the additive fluid for his humidifier made me wonder ... Our
little cheapo Sunbeam that we use in the bedroom gets to where it won't put out much humidity. At
first, I thought it was because our well's hard water was clogging the filters, so I started putting
in water that's been thru a Brida filter. Sure enough, less white gunk in the filter but still gets
to where it won't humidify much. So what if I put an eyedrop of Photoflo into each full tank of
water? Would that increase the surface tension of the water so more "sticks" on the fan blades and
thus solve our problem? Or would the Photoflo just soap up the carbon filter?
