How to clean the tube on the HOB filter?

I use a brush that came with my turkey baster from Target, meant for cleaning the baster. Works like a charm!

It's the disassembly of the filter that is the tricky part, but once you've done it once you can do it every time. I didn't clean my filter for a year, and it started acting up. I took it apart, cleaned every part out thoroughly with plain water, put it back together, and it works like NEW again.

Definitely worth the effort. Saves you the $50 for a new filter!
 
I use a bottle brush <for baby bottles> or a pipe cleaner on a string. Very easy and effective.

since I smoke pipes.. I have pipe cleaner laying around
