TDS Meter reading...thoughts?

i would be worried about if your carbon blocks are exhausted and chlorine is being removed, also not sure if houston uses chloramine(need a filter for that). i think all units are basically the same housing wise, but the filters are the key factor. as with everything you get what you pay for, i try to buy the best performing filter for each stage. i run filters from brs or buckeye and have been very happy with their performance. i change out sediment and carbon every six months, it also helps to have pressure gage before the ro membrane so if pressure drops you know its time to change the stages before. also having a dual tds helps, that way you can see whats going in and out of DI stage, again once you start seeing numbers creep up you can figure out when its time to change them.
