Carbon filter material

[RJH]

I've a Lidl dehumidifier (SLE 420 A1) and am having difficulty sourcing
original carbon filters. Even if I do get a reply, they're likely to be
expensive (for example their workshop hoover bags are £17/5 plus p+p).

Is there anywhere the material can be bought reasonably cheaply, and cut
to size? It's 3/4mm thick black light plastic foam-like in appearance,
about 30cmx30cm.

The usual online suspects

<https://google.co.uk/search?q=activated+charcoal+filter+foam>

Aye yes, thanks, but that turns up mainly pond filters - it's the 2/3mm
thin that I can't pin down. And cooker filters tend to come as packs,
with a grease filter. Which looks like that's what I'll have to do -
just seems a waste.

Why would you want charcoal in it? Filter paper or cloth should work.

Or foam made for the purpose. I guess carbon refers to the colour rather
than an attempt to imply activated charcoal?

It is mainly a dust filter so if you don't mind cutting it yourself
(and not having the largely ineffective carbon bits) Dunelm and
similar sell 70g wadding material
http://www.dunelm.com/product/70g-wadding-material-1000002018?searchTerm=wadding
for £1.50 for a 1m by 1.37m bit.

It easily squashes down if a bit thick. I've used it for external
venting cooker hood filters for years.

The idea of the charcoal/activated carbon is to remove cooking odours.

Recirculating filters are a complete waste of time.
The best thing is to chuck the crap outside.

Maybe we should stop circulating crap round the house then. :)

So you've already got a nylon air filter then a wet surface to clean the air. So again why would you want more? Sometimes you need to think about it.

No, you're right, I can sell you superelectrowonder filter cloth for £10 a square metre. It looks like bogroll but omg it's fantastic.

Not a wet surface, no. The nylon mesh is fairly coarse and has never
visibly clogged. The carbon filter OTOH is pretty bunged up. I've been
running it without for quite a while now.

So again why would you want more? Sometimes you need to think about it.

Yes, I'm not sure how it would actually achieve a great deal in my
situation. But as it was designed that way, I thought I might as well
replace it with something approaching the original.

I've got no intention of replacing it every 6 months (as per the manual)
- this will be the first change in over 3 years, and I'm doing it mostly
to stop muck getting in to the machine's internals. I agree the carbon
seems superfluous, but if I can without too much expense or bother, I will.

> Recirculating filters are a complete waste of time.

Not if the filtration system is capable of taking muck out of the air
(which this almost certainly isn't - unless it's somehow pushing it into
the condensate) and you're susceptible to that muck (which I don't think
I am - in the short term at least).

Or not allow it to develop in the first place etc. I'm not that bothered
about that side of things anyway. I just want to keep the thing working
properly.

You can buy the foam from RS or Farnell, maybe Rapid. Try "conductive foam".

Try searching for conductive foam.

I threw all the filter components away years ago. It vents to
outside. Last year, the fan went noisy due to crap build up, but a
liberal application of Screwfix penetrating oil over a few days on the
sintered bearings has restored everything to as new, after some 40 years
of working!

No, I don't. I have enough functioning brain cells left to understand the situation.

You do know that a carbon filter will take out smells like farts and
volatile organics and stuff like that as well as cooking smells?
They also take out ozone which may be a problem if he has an old laser
printer and hasn't fitted a new filter for years.

You can buy mats for aquarium use which I have fitted to my dehumidifier
while decorating to get rid of the paint smell faster.

Even my car has a carbon filter to remove some of the smells from that
dirty diesel in front. Not that it has enough carbon in it to last long.

Precisely, it is a limited. And entirely unnecessary.
