Other - Filters - Where in the heck to get them?

[3xtr4]

Ok,

So SWIM has been searching all over his local super market for coffee filters. All he can find are packs of 10 re-usable mesh filters that are useless. He finally thought he got lucky, only to read robo's guide that said not to use these (SWIM tried to link the picture but I cant due to my post count. Check robo's guide for the filters SWIM found).



These are the exact ones SWIM found. Damn. SWIM is in the UK, so Tesco is his main stop. He knows he is looking for cloth-like filters and not paper filters that he already has from long ago (they are quite small too, circular lab filters).

He can't just ask a clerk for filters that are CWE suitable, so where do the rest of you UK people get them?
