I need to take a poll. In my ro/di filter, there are 3 pre-filters. Mine has 2 sediment filters (5 micron and 1 micron) and 1 carbon filter. I see a lot on ebay that have 1 sediment and 2 carbon filters. What do you all have? Do you know if one is more beneficial than another? I need to buy some more filters.
