ZeroWater Tumbler ZR-230 Travel Bottle Filters (2 Pack), 1-Pack, White

The level of particulates in the water determines how many gallons of water per filter you can get from this system/pitcher. In Arizona, I can get EIGHT GALLONS OF WATER PER FILTER only. Guess I'll keep buying bottled.I sure wish the product description had mentioned this before I went through the hassle of purchase and return.The particulate map was included WITH the purchase but should be a part of the initial purchasing information. I would not suggest this product as a good alternative to bottled.

I love my Zero Water tumbler it filters water better than other tumblers I have tried. I also have the Zero Water pitcher. The water come out tasting fresh. Personally I believe this is the best simple purifier on the market. The downside of this product is after some use. The filter can leave a fishy smell in the water. I tried drinking the water and it had no bad aftertaste,however,the smell was a turn off. I will definitely buy this product again!

So so so disappointed in this product. I purchased 2 of these and both have already broken from normal use. I have Zero Water's pitchers and love them (even bought everyone in my family one), so I was excited to see this tumbler that I could use when traveling and don't want to carry a bunch of bottled water. Within a week, on of the straws broke from being dropped on the floor. A week later the tumbler itself cracked despite my hand washing it and really using it under normal conditions. SO onto the second tumbler. Basically the same issues. Low quality materials. the threads of the filter caused leaking and when I tried to find out why water came from the threads not the filter, I saw the threads also had a crack. Gifted one to my mother as well. She accidentally dropped the tumbler on her wood floor and the plastic cracked.

It doesn’t hold much for the size and mine cracked after a few days. I love Zerowater products and thought this would be a great travel bottle. I put the filter part into a larger bottle and that worked better but was a bit bulky.....but at least it didn’t leave. I later fixed the crack with some super glue and scotch tape and it’s holding fine but still a small drink of water.

I love these filters. In my opinion Zero Water filters better that any other filter. I always drink water out of my tumbler. This really makes my water tastes great. The bad part is after use the water can smell fishy,however,the water does not taste fishy. Just change the water filter out. Will be buying more!

Does this work as intended? Yes. However, you can't fill it by filling the reservoir just once - you have to fill it, then wait until it slooooooowly drains, and then fill it up again to get the full capacity; at least 10 minutes total. I'm under orders to drink a gallon of water a day - if I used this, I'd be hanging around for over an hour each day just watching water drip through the filter. Also - while I love the concept of portability and using it anywhere, it's really quite big and heavy for the purpose. Usually I carry a water bottle when exercising or walking, and this thing is heavy and massive. I'll be returning this and buying a ZeroWater pitcher instead, and will fill my regular water bottle from that. I love the concept but not the tumbler. I'm looking forward to spending less time watching water drip...

The ZeroWater filter technology is outstanding! I have owned reverse-osmosis systems and have consumed countless gallons of bottled "purified" water. The ZeroWater system requires no expensive equipment and consistently provides a taste quite superior to either the flat tasting RO methods or the plastic bottled competition. Importantly, I know exactly where the water has originated; know exactly how long the water has been sitting in the container; and can even test the purity with the electronic sensor [available separately]. Note: The travel filters also include a built in "time to change filter" indicator as well. I just feel safer with ZeroWater!!!

Great idea, but they have to be replaced weekly. In some cases, my filter actually backed up and sent the filtering material into the water tank (not the drinkable part, but the pre-filtered water part). I'm just not sure it's a good value if I have to keep replacing the filters every week. (But I haven't done a cost-comparison between buying a case of water weekly, or getting delivered water - neither of those options are very earth-friendly). I like ZeroWater's larger tank options and then keep refilling my BPA-free water bottle.

Ridiculously priced! Bad enough that the drinks container isn’t versatile due to have a straw hole ! They can only be used in the house or garden rather than taken on walks etc but on top of that lack of versatility, the cartridges are expensive ! Marked down due to price and the fact they don’t last long at all. Also the indicator to tell you it’s time for a replacement cartridge is a joke! I haven’t got any issues with colours etc but I can’t seem to tell the difference between an unspent one and a spent one.

Great

I apparently ordered the wrong ones and can't exchange them for the right ones.Then I thought in order for this not to be a total waste of money, I would order the travel bottle, but it apparently does not exist? A total waste of money.

Make sure and check the photo on the box before you buy. This product is for a small portable zerowater jug, not the 6-cup refrigerator size jugs. Amazon will not let you return it.

READ DESCRIPTION! This product is for the Tumbler (which I don't even think exists). You also cannot return this item so it's essentially garbage.The supplier needs to allow returns of theses!!!
