Just based on reading about it and looking at it, here are a couple of observations. 1) I don't like the inline DI
filter. It isn't clear so you can't tell when the resin has exhausted unless you're doing TDS
checks. It's smaller than the canister type and will not last as long. If you get a DI
filter that doesn't have quite enough resin in it, it will settle to the bottom and the water will bypass over the top of it. 2) The prefilter canisters are not clear so you can't tell by looking when the sediment and carbon block filters are dirty. 3) I question the need for the 5th stage carbon filter. 4) The statement that you only need to change prefilters every 6 months or every year for the high capacity filters is misleading...that's only the average time. Actual replacement intervals are dependent on your water supply. 5) I prefer a unit that uses a Dow Filmtec membrane.
OK, so that was more than a couple
. At the least, if I went with this unit, I'd get it with clear canisters and a clear DI
with color changing resin. I would also look at the Aqua FX units. I know they cost more, but I think they're worth it. JMHO
