For us, the winner is distillation (with a charcoal filter) for purity, cost, and reliability.
Zero Water is great and even though it is very pure...zero dissolved solids...it doesn't kill bacteria or other pathogens. (They say they're working on it.) Also, a Zero Water filter lasts about 12 days at my house. Our water tests at 260 ppm of total dissolved solids. (Love those little testers they provide.) At $15 per filter you can purchase a distiller in about 3 months! So until the filters last longer and also kill microbes I won't be using this one for every day water needs. We do however use it when we travel for convenience.
Brita took my dissolved solids number down about a hundred points...not acceptable. It also won't filter pathogens.
RO makes pure water, but as most know, it wastes a LOT ...a minimum of 4 gallons is required to make 1 gallon of pure water. That's costly unless you're on a private well, but the units are also pricey. When we used RO we had to call for a technician to replace the filters, so you pay for the service calls too. Pathogen overgrowth in the filters may be a problem between service calls.
I've had a Berkey for nearly a decade. I blindly trusted that it was working. If you can't test your water regularly you don't really know whether it's working or not (and I don't want to periodically run colored water through to test it.) So, using the little ZW tester, the Berkey brought my dissolved solids number down a whopping 10 PPM! I was shocked. Also. A couple of the filters came apart at the base (defective) and they won't replace them. My stored (unused) filters won't work at all and had to be tossed. The one thing THEY SAY the Berkey will do that the others (except distillation) will not, is remove pathogens, but I havent tested to see if this is true. Also, never ever let a Berkey filter dry out or it will literally never work again. It becomes completely plugged. At $80 plus per filter, Berkey gets a thumbs down from me. Perhaps someone has used a Berkey to filter creek or pond water with good results. I have not tried that and hope I never need to.
Distillation makes the purest water but you will want to use a carbon filter too to remove VOCS (volatile organic compounds). You can google a list of these. Distillers usually come equipped with a small reservoir in the output nozzle for charcoal packets. I ordered a bag of activated charcoal and reusable tea bags to save $. Be sure to buy the larger chunk and not the finely ground charcoal.
I hope this was helpful! If anyone had different results or experiences I would be interested in hearing about them.
