Hello, Terry, No. I would avoid the type with any metal. I use the Perma-Brew all-plastic filter manufactured by Tops Mfg. Co. Inc. of Darien CT 06820. It has a 3-year warranty and is dioxin-free.
It can also be used as a prefilter with a paper disposable postfilter between it and the funnel. This way, you can check visually to see how well it filters. It also holds the shape ot the paper postfilter, extending its lifespan. Pre-rinsing the assemblage with DW can remove some or all of the objectionable solubles in the paper postfilter. Matthew
