Hi all,
I’m in the process of making my own fume extractor.
I’ve been following the link at the bottom of this post.
I have now got everything except the actual filter medium as I’m not sure the way he’s doing it is the best way?
Basically it’s a deep plastic box with an in line mixed-flow fan, the exit going through the side of the box. And a smaller box that sits inside with the filter medium in.
It’s just the design of this smaller box that I want advice on, the fan etc is already here, waiting to be installed.
I’ve hopefully set the link to 19:36 where he shows how he does the filter.
He uses two 30mm thick cooker hood filters on a cardboard gasket and covers the entire box with white wadding type stuff.
I was thinking that instead of cooker hood filters with cardboard gasket etc, permanently installing something like a couple of 200mm (8”) flanges (or smaller, maybe 150mm/6”) , like in the below pic, but ones that allow me to put in metal mesh at the bottom of the flange.
Then I could simply fill with loose activated carbon and cover with hepa filter sheet?
I’d imagine in the long run this would work out a lot cheaper as those 30mm thick filters in the YouTube vid are around £10 each + delivery and activated carbon for aquariums can be bought fairly cheaply?
(I will also make sure a hot knife is used to cut everything so the brittle plastic doesn’t shatter/break).
Anyone think my way is worse than his or can anyone think of a better way altogether? Again I’m doing it roughly how he’s done it and already have everything except the filter medium.
Many thanks
