So I just found out Lynn Water supply is being diverted to MWRA . Lynn has a track record of the best water quality in the country . I have done work for the MWRA and they are no slouch . but in such a broad water distribution system there are contaminants that can get in . My unit needs new filters as it is . Time for a new one I think . I know Air water and Ice , BRS , there was another one we had as a sponsor I can't find on forums anymore . I don't want to spend a ton of money on this . so what would you use ?
