I've used a few different kinds. All work well, but I use the little filters too.

Yes, I believe it uses the larger cone-type "Mellita" style filter. Much easier for cleanup.

It comes with a filter in the machine itself but no extra. Hope that helps.

It is a plastic and mess type filter that you use over and over again, i.e. permanent filter. It's very easy to clean also. I hoped that helped!

I don't know. I use distilled water and that eliminates the need for a filter.

This is the second unit I have purchased so I wanted extra filters. It comes with one of each of the two filters it uses.

It uses flat bottom filters. We like the maker and the matching toaster a lot.

It takes the big filter. I believe A size. I use an Intex sand filter with mine. The upgrade was well worth it.

I don't know the answer to that, I just use the filters that came with it.Remember to clean them after each use.

Basket paper filter. You can use a gold mesh filter but they allow too much sediment to pass into the carafe.

Who knows? There are better filters out there. The one I got did not come with any paper work that details its campliblities. A monolithic filter or the ones that go in a Berky are good filters. They list exactly what they filter out.

Dunno. Don't have one. This is not a great filter....returned due to scratches right out of the box...

I use a paper filter! To me you need one, I don't get that permanent filter term they use. You need a filter!

You clean it with a damp sponge. If that doesn't clean it completely, you can wash it with soapy water. You have to make sure it is completely dry before putting it back in. You never need a replacement filter.
