Sadly, the three stooges can't read.
That was a joke and not a personal attack either, so laugh and continue reading (preferably the entire piece of what I said, not picking and choosing random quotes out of context).
I did, you just conveniently passed over it.
All of which are replaceable for less than $200. The increase in initial cost does not justify the purchase, plain and simple. I seem to remember and you failing to provide details on these supposed higher quality components. When you can do that, maybe your statement will have some validity. Until then, it's the equivalent of saying your "good" system is better than our "fine" systems.
So, what does get you a guaranteed accurate rejection percentage? I'm sure that for the more expensive RO systems out there, you send them a sample of your source water and they test it against that, right? Or no? Because if not, then even a "high-end" dealer's claims are suspect.
Funny, my Ebay unit for $92 has a Dow membrane. Considering there are very few membrance manufacturers out there, there aren't many options to choose from. What OTHER problems? I've never experiences a one of them. I've seem high-$ SpectraPure units that put out crap water. What about THOSE problems? Or do they not matter in your little world?
BTW, there are lots of non-Ebay seller where you can get nice RO unit cheaper than some big names with the exact same equipment. I don't begrudge them for selling them more (they've got advertising costs, etc.), so I wonder why you begrudge cheaper units? You've yet to provide any substantial evidence that more expensive units are better. Until you can do that, then I don't think anyone is impressed or convinced.
And he, or you, would know this how? I have no clue what's in his water, and I'd guess that everyone's prefilters will look mighty different. Concluding yours are "better" based on visual observations isn't a really good basis for the assumption it's better. It says to me that for sure, the one guy's whose is dirty is filtering stuff out. How can I be sure about the other one? What if it's leaching things into the unit and destroying the membrane faster? Of course, it couldn't be doing that, oh no, because it "looks good". Good call there.
Fair enough, but who's fault is that? If you're not bright enough to wonder why your DI cartridges don't last very long, then this likely isn't the hobby for you. My unit has made me about 300g of 1-2 TDS water so far with no discoloration so far. When it gets worn down to the point things need replacing, I'll likely upgrade a part or two. $92 well-spent. Still works just "fine" in my books.
Micron rating would have been more accurate. Sorry if I made that difficult for you to decipher. Here I thought with all your other insightful thoughts a smart guy like yourself would be able to figure that one out. My apologies.
Yet you have not explained what the problem is or why the math is wrong....
I did, you just conveniently passed over it.
You do NOT pay $200 to just get a better membrane. That is a misleading comment and why these threads are as long as they are. DO we really have to rehash this whole thing again? Filter quality?, Component quality?, Resin configuration, Resin Quality, Customer service?, etc. You are free to buy what you want, but please do not insult the rest of us who understand or find VALUE in quality built systems.

A $38 membrane does not get you 99.25% rejection unless you are very lucky. Yes an occasional one comes out in excess of 98% but its very rare and is not guaranteed to do so.

Firstly MOST users would not even know to change the membrane. Secondly, MOST users would not know what kind of membrane to buy. Thirdly, MOST of the "eBay" vendors peddle lesser membranes but advertise them in a manner that portrays them as superior to the DOW FILMTECS. Nothing like buying from a dishonest vendor! Moreover, it is not a simple $38 difference. You are ignoring all of the OTHER problems with the units.

What he was trying to say was that the better filters have more surface area. Therefore, used under the same conditions as a SMALLER filter or one with LESS surface area, the better filter will show less visible signs of use.

The PROBLEM is that it does equal out. There are masses of people out there paying out the nose to refill their DI chambers because they purchased junk from eBay. If you do not believe that, then I have a bridge for sale CHEAP.

BTW Mr. Scientist did you Mean "Micron Rate" or "Micron Size"
