HC150, rainout, inline filters for allergies

I had thought of that. Thanks for confirming that the Philips claims are more than marketspeak. The HC150 is supposed to have similar technology. I wonder how well it works.

Here's a wild idea: What if I put an inline filter, perhaps one of the semi-hydrophobic ones, at the highest point of the hose and gave it a small heat source. I could put it in a box with a nightlight bulb or a few resistors and maybe a simple control circuit. Water that condensed elsewhere would not run into the filter, and theoretically, no water would condense in the filter because it would be heating the air slightly instead of cooling it. This, combined with a humidifier that regulated humidity according to the ambient temperature, might work.

It's more than I'm up to doing now. But I used to tinker things together all the time, so maybe I could do this after I get some decent sleep.
