Just finished refilling my carbon filter... Easy as falling off two logs at once.

Filter: Rivets (4 round the top of the filter): Drill off the heads:
Use a wide drill, be careful not to drill into filter. Repeat on the other rivet heads: Tap gently under filter rim and remove top:

Pour out the old carbon (beware of dust, use mask), remove remainder of rivets from inside: Put filter in bag to catch dust and any carbon you spill: Clever bit:
Pour new carbon into filter a bit at a time... use vibrating sander pressed on inner sleeve (with cardboard pad to stop mesh cutting sander foam base).. shaking the inner sleeve seems to settle the carbon really well (or at least as well as I'd expect to do it without a proper vibrating thingy) shake between each load of carbon (I was using a 1 litre jug) and move the sander round to shake it all equally. Once you've filled it with the new carbon:

Pop the top back on, being careful not to distort inner or outer sleeve.
Take care to align rivet holes.. they're unlikely to be equidistant.
If you have a pop riveter, replace rivets, if not, use short thick self-tappers. Scribble the date on it, so that you have some idea when it might need replacing again:
Attach the fan... blow through the filter for 10 minutes to displace any dust: Remove and reverse the fan .. suck for 10 minutes to clear any remaining dust:
That's it!
Filter ready to go back into the system:
Took me a couple of hours, not including cigarette and coffee breaks.

the manufacture of that unit would like to have words with you...



well done

normally when i take things apart,
i use a marker to note where they had been prior to my fiddling


did you have to rotate the top a bit to get new purchase for those screws
or did the old rivit holes work just fine?

You have lovely hands.

And good taste in tools.

No, that's my wanking arm.

The other one is about half the size.

No, the old holes worked OK.
I was going to use new pop rivets, but our local hardware store didn't have any in stock.
Luckily I had some chunky self tappers in my box of miscellany.

great pictorial

And here it is back in situ:

How effective at odor control is a setup like this?
