@machesta Hi, there! I just get them off Amazon. I had asked Dr. Falkinham if I needed to worry about the carbon in the stage filters of the sediment filter, and he said because it's before the .2 micron Safe Water (or whatever one you use) showerhead, it wasn't a problem. I just looked for one that had extra filters for it and would work with my handheld. It was about $30, as I recall.

Yes, I am. I have the 886 for my travel trailer and when we take trips by car as well. I have been using the 886 plus in my home shower. I may eventually just use the 886. It has half the capacity of the plus, but I take short showers and don't shower every day, especially in the winter. For comparison the 886 will filter 1360 gallons approximately and the 886 plus will filter double that amount. It is larger -- longer particularly, which is why I started with the smaller one for our travel trailer.
