Hi Talk_coffee and Barry. Thanks for your warm welcome Barry, yes I understand exactly what you mean - you guys need Reverse Osmosis to remove TDS (totally dissolved solids), which is why I said I would never recommend a carbon block counter top to you (or undersink). For serving water in a commercial environment I think when we are talking about micron size, and the certain things that are left in/pulled out of the water it is very relevant, just as relevant as removing TDS in my opinion.
All I am saying is our products never claim to do anything they don't or vice versa - we do have one of the best carbon block filtration systems around, but if one of our reps told you to use that inline to your coffee machine claiming it works the same as an RO system you should ring the company and report them! I understand your distrust in door knocking sales people Talk_coffee, I felt the same way until I was on the other side of the door, and still feel the same way with a lot of them - but in the end it's your dollar and your health, so if you end up continuing to buy inferior or cheaper cartridges that don't work quite as well or need to be replaced more often, or use cheaper plastics just because they are recommended by another company trying to make a dollar (isn't any company?) then I can't stop you from doing so, I just wanted to clear up some misconceptions here about the company i'm working for, and cheaper products that are claiming to do the same job for a cheaper price. Pws specialises in water filtration, and although yes it may be drinking water, it's not hard to read through this thread to see you were talking about TDS, which means you need an RO system (am I wrong?), that doesn't make my professionalism have any less relevance to your needs than say, bombora, does it?
If you want to "leave it to the professionals" you are probably better off talking to a company that specialises in RO filtration, not one that specialises in coffee with a side serving of filtration
Thanks again!
