Carbon filter material

The usual online suspects

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?

I'd assume some sort of additional filter perhaps aimed at the 'air cleaning' mode. There's already a washable inline nylon mesh filter.

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

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 ai r. 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 £

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.

Now now.

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.

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.

Years ago, integrated circuits and circuit boards used to come packaged in a black anti-static mesh a couple of mm thick, which looked identical to the filter we had in a de-humidifier. I've had a quick google for the stuff but can't obviously see it. Not sure I'm using the right search terms anyway. Maybe they don't do it anymore. These days circuit boards come in plastic bags closely printed with a conductive pattern.

But a dehumidifier will work perfectly well without a filter. The dust just collects on the cooling fins and washes off into the container below, at least it does on ours. OK unless SWMBO wants to use the water for the steam iron.

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

Try searching for conductive foam.

Ah, that's the stuff. Thanks to you and TW. Perhaps the OP should try some; take your...er ... pic!

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.
