For their long-term travel in the UK, my grandparents are staying in older hotels where staff have warned them to boil and filter tap water before drinking. The difficulty is that each of their rooms (so far) contain only 2 water sources ─ 1 showerhead and 1 set of separated taps as follows ─ but the red space between the taps is always too narrow and tiny to support anything, much less a water filter.
They will boil the water with their kettle to kill antigens ─ thus the water filter does NOT need to do this. But what removeable water filter can they use to filter out 1-4 and 6 underneath, because pitcher filters cannot do so?
