I would do sediment, 5micron, 1 micron, ro, dual di
that’s my system and I get 0 tds out of di.
im upgrading to use individual di in front of dual bed di to save di resin and cost but that’s not needed unless you make a lot of water
also make sure you flush ro before you make water. You will chew up di when the system comes on. I flush my ro for 5 minutes till tds is low then I make 50 gal at a time.
not sure 2 sediment filters is going to help. But the 5 micron to 1 micron before ro will
