I'd replace the micron filter (the first one) and then make some water. If your TDS is 5 ppm or less, then the filters and resin are probably okay. If the DI resin is good, the TDS should be 0 or 1 ppm at most.

Pretty sure You need to Keep the Di Wet during prolonged storage, So might not be any good. Sure someone with more experience will chime in.

After I stopped using my unit, I never flushed the remaining water out so I should be fine but we'll see once I hook it up and put it back not use.

make some water and see where your at. probably wouldn't hurt to change your filters anyway.
