ZeroWater is the reigning King of low-cost water filtration devices. Seeing your water purity go from 150 to 250 PPM of contaminants, down to literally "000" is exciting. No other affordably-priced water filters can do that. I give it "Five Stars" for quality and affordability. However, there is a "dirty little secret" that ZeroWater desperately hopes you don't discover: ... how to make their water filters last 5 times as long, without sacrificing water purity. I will tell you the secret: The company makes its money on selling you $10 replacement water filters that only last about 30 to 50 gallons, and then the water impurity level starts to read more than "0.06" (the company-recommended filter-change interval). For most couples or small families... that means a new $10 filter about every month. Wait a minute! You mean that this filter purifies my tap water from over 150.00 PPM down to a negligible 0.06 PPM, and at that point... while the filter is still operating at OVER 99.9% EFFICIENCY... I'm supposed to discard it, and buy another of your $10 filters? Because 99.9%+ purity is somehow "unacceptable"? That's crazy perfectionism! Here is the SECRET to maintaining a purity rating of under 006 PPM for 5 times as long as the projected 30 to 50 gallons per filter... to get instead 150 to 250 gallons per filter replacement: Step One: Buy ZeroWater's big 23-Cup Filter Device (Item # ZD-018) for less than $40 on Amazon. Step Two: Buy ZeroWater's 10-Cup Pitcher Filter (Item # ZP-010) for less than $30 on Amazon. Step Three: "THE SECRET CYCLE"... Fill the easy-to-manuever 10-Cup Pitcher at your kitchen sink, and filter your water through it... ... and THEN... pour that already-filtered-water (reading 000 - 100% pure) into your big 23-Cup Filter that stays in your refrigerator and let that filtered water be filtered AGAIN. This results in your Big 23-Cup unit's filter receiving ALMOST NO impurities through it's filter. As your 10-Cup Pitcher's filter slowly clogs with impurities and degrades down to the dreaded "006" level... DO NOT DISCARD IT... just keep using it until it gets to 3 or 5 TIMES that "impure"... which is "018" to "030" Note that this is STILL quite PURE.... even at this level that is3 to 5 times beyond the manufacturer- recommended point of change... that water is still very pure and drinkable: but wait... don't drink it... instead: POUR that 90%+ purified water from the 10-Cup Pitcher... into the big 23-Cup Filter, and filter it again... down to "000" (or at least well under the "006" level... which is 99% to 100% pure). Your filter in the big 23-Cup unit is thus always receiving water that is almost totally pure to begin with, so IT'S FILTER DOES NOT CLOG OR WEAR-OUT... IT LASTS FOR MONTSH AND MONTHS. When the Big 23-Cup unit's filter finally (after a very long time) reads "006"... you can take that filter... and PUT IT IN YOUR 10-CUP PITCHER as the new "pre-filter"... and pop a brand-new ZeroWater Filter into your big 23-Cup unit, and you are good-to-go again... for a very long time. That's the whole cycle. That's the big secret. That's they way to get 150 to 250 GALLONS out of each $10 filter... rather than just 30 to 50 gallons. Buy 12 ten-dollar filters per year... or 2 to 3 ten-dollar filter per year... the choice is yours. Isn't it brilliant in its obvious simplicity? Happy Filtering!
