ZeroWater 26oz Portable Filtration Tumbler and 2-Pack Tumbler Replacement Filters - ZT-M01

Leggendo le varie analisi di laboratorio ed i vari commenti degli utilizzatori, mi sono convinto a dare una chance a questo 'bicchiere' con filtro della ZeroWater. In pratica, la sua particolare tecnologia a cinque stadi (normalmente la concorrenza utilizza filtri ad uno, massimo due stadi) permette infatti di ridurre praticamente a zero i minerali disciolti nell'acqua del rubinetto (non filtra eventuali patogeni quindi l'acqua deve essere necessariamente potabile!).Ora, se da una parte mantengono quello che promettono (lettura dell'acqua in uscita: 0 TDS!), dall'altra ci sono due insormontabili problemi ovvero il sapore e l'autonomia. In altre parole, con un acqua dura (tipo quella di Roma con un residuo fisso di 480/500 mg/l) il filtro satura dopo 4/5 litri ! Avete letto bene: il filtro vi durerà un paio di giorni ... tre al massimo !A prate questo, cosa già di per sè grave, l'acqua già dall'inizio presenta un retrogusto di resina e la cosa peggiora con l'uso.Dulcis in fundo, se in America questo oggetto viene venduto sotto i 20$ (ca. 18e), quì da noi costa 50e cosa che, sommata al resto, lo rende immediatamente un pessimo acquisto !Per riassumere:Pro:------ portatile- riduce veramente i sali disciolti nell'acqua a zeroContro:----------- autonomia risibile (4/5l)- sapore dell'acqua da subito 'resinoso' (e la cosa peggiora con l'uso!)- costo esorbitante (almeno da noi)

I figured I would give this a try at my office. The cup with the filter inside will hold 20oz of water. It can filter about 10oz at a time with what the upper cup above the filter will hold. It takes 1-2 minutes to filter about 10oz of water. I usually keep another cup or larger tumbler that I refill at the fountain and then dump over as the filter cup gets low. It's not really portable in the sense that if you would carry it to where you are filling it you are only getting about 10oz of water or waiting 1-2 minutes before adding more water. It does do a good job at filtering and makes my water at work not taste like treated city water which is what I bought it for. I usually refill the cup fully 2-3 times a day and the filter lasts me about 2-3 weeks roughly. You can use it longer than this from experience but it's effectiveness does decrease over time. I am not sure if it will help but I decided to post this review to give some measurements and an idea of what to expect from this cup.

UPDATE: This product broke after just a couple uses, before I even had time to use the 2 replacement filters that I bought for it. The plastic was just SO BRITTLE. I'm extremely upset.---- I love the concept, but it's not perfect. I wish that this came in a larger size, with an opaque cup instead of a see-through cup. It looks weird - I think that the plastic should hide the filter instead. Also, the straw and cup feel very brittle and breakable. I hope that Zero Water will release a better version of the tumbler in the future because I really like their filters.

Awesome cup for travel and on the go when you only have tap water and Want it filtered! Works well and makes most bad taste go away, not top quality filtration but good for what it is...Easy to use, wish the overall fill of clean volume were slightly bigger but I assume they chose the ratio for many reasons. Good enough!Like having a backup filter bc I go thru Em fast.And have brought empty through airports and then saved a lot on bottled water! Try it!

Like others, I dropped it (on carpet), and it broke pretty easily with the force of the straw going through the bottom of the cup. It completely cracked the bottom. This is a very cheap design given how much technology goes into the filter.I am happy with the overall idea but disappointed with the tumbler's quality. I'm going to buy another because I value the idea, but it's pretty disappointing, and I'm going to have to be very careful from now on.
