Maybe they are mincing words between "Relative Humidity" and "Absolute
Humidity". Only RH changes with temp, abs humidity is constant with the
volume of water in a volume of air while RH measures water content relative
to the saturation point which changes with temp. Since only RH effects
comfort levels, it would be underhanded to make claims based on the other.

I've not seen the ad. Is there a web link?

Sorry I misstated...they claim it DOESN'T reduce humidity...
Yep, the ads have been around forever, but this is unusually
flagrant, I thought, given the price.

Heating equipment does not lower humidity, raising air temperature does.
