Jeff-C175 7,203 #2 Posted September 8, 2021 (edited) Water quality is one of my 'things' so I did find it interesting, thanks! The TDS test is good, but he does admit that it's not an all inclusive test. TDS is not nearly as important to water quality as the filter purveyors would have one think. Removing Iron is difficult and typically requires a Zeolite resin ion exchange. One of the filters he opened appeared to contain Zeolite. The ZeroWater is the one with the Zeolite: It appears to also have a layer of activated carbon above the Zeolite. I wonder how much they get for the replacement cartridges? They say the cartridges are 20 gallon capacity. In theory, they could be backwashed with a brine solution to 'recharge' them for more use. That's what they do with they typical whole house water softeners. Too bad he couldn't test for water borne parasites such as Giardia, Crypto, and amoeba. that's quite important! The only filter he tested that's really got a prayer of dealing with water borne parasites is the Reverse Osmosis. One of the three cartridges in that system is likely Carbon. If one wanted to be REALLY A.R. about their water, they would use multiple cascaded filters. 1. SEDIMENT (filter paper) <-- even with city water, one would be astounded at the amount of sediment that would be collected! 2. ION EXCANGE (Zeolite) <-- city water typically has low levels of dissolved iron, the water treatment plant takes care of that. 3. CARBON (taste and smell, and CHLORINE!) <-- recommended for city water. 4 ULTRAVIOLET (water borne parasites) <--also not typically found in city water. Optionally, follow the whole setup with a REVERSE OSMOSIS under sink for drinking water only. The drawback to reverse osmosis is that it is relatively low flow and it wastes as much water as it filters. Waste water from the process goes down the drain. It can't produce the GPM needed for regular household use. If one were a total plumbing nut (like me!) they could tap off between filters 2 and 3 above to supply the toilets, washing machine, and outdoor faucets to reduce the load on the Carbon and UV filters. But that means basically two separate supply systems. Edited September 8, 2021 by Jeff-C175 1 Share this post Link to post Share on other sites
