Pretty good

So far so good... one thing that I would have as an option is a dark colored glass. Filtered water as it stands can develop algea due to chemicals that prevent such things being removed. Dark glass would help stop algea growth.
I would recommend this to a friend!

Love Zero Water when it works
on June 5, 2024

Length of ownership:1 year or longer
We have been using Zero Water filters for over a year now and we love it when it works...always have to bang/tap the unit to get rid of the air bubbles after filling top reservoir or the water will not flow through the filter. Hopefully they figure this issue out.
Response from zerowater.comBy ZeroWater TeamJune 6, 2024
We certainly apologize for the continued frustrations with the filters, typically this is an easy and quick fix, simply remove the filter from the container and unscrew it from the tray. Then hold the filter sideways/horizontal and grip the filter very tightly and shake the filter with some good force side to side and back and forth 8 to 10 times. This will loosen the filter media and break the air lock. If you do not clear all of air from the filter this issue will continue to compound itself over and over. Also never fill the reservoir directly from the faucet or spigot from your sink as this is naturally aerated and will force air down inside the filter. It is best to fill the reservoir with a large glass or measuring cup and pour into the corner of the reservoir away from the center of the filter. If there is ever a filter that simply just will not fix itself when the aforementioned trouble shooting steps have been followed we are more than happy to replace that filter. Again, we apologize for any inconvenience this may cause.

Fishy tasting water
on January 30, 2025
Posted by: S Cristofani
Length of ownership:6 months
I bought the glass dispenser summer 2024 but did not put it to use until fall 2024. By December we noticed a fishy smell and taste. We thoroughly cleaned the dispenser and put in a new filter. 7-10 days later fishy taste and smell. Cleaned again, put in a new filter and 5-7 days later disgusting fishy taste and smell. The water did not sit. We used it everyday. Very disappointed. Now I have a beautiful glass dispenser (because we wanted to get away from as much plastic as possible) on my counter that I can't use. Looking at another brand that has a glass dispenser.
No, I would not recommend this to a friend.

In order to avoid a change in the taste or smell of the water it is important to test the water regularly as recommended and change the filter when the digital meter reads 006.

If you are going through filters that quickly that would mean your tap water is likely in 400ppm range which is extremely high and would cause the filter to get over worked rather quickly.

Generally good, but I wish the spigot was more substantial. Overall I am satisfied.

Love the idea of glass!
on March 15, 2025

Length of ownership:1 week
I love that's its a glass pitcher as opposed to plastic. So many issues with plastic. The only thing I am really disappointed in that the spigot is too high up on the container. There will always be at least 3 inches of water that won't ever be drank unless the container is tilted and it's so huge without a handle it's impossible to tilt it.
No, I would not recommend this to a friend.
Response from zerowater.comBy ZeroWater TeamMarch 28, 2025
The glass container is meant to be filled continuously, thus making the water beneath the spigot irrelevant. Once the water tests above the 006ppm mark simply empty the entire container into your sink then rinse, dry, and replace the filter. Thank you for your feedback.

Great water reservoir
on March 18, 2025
Posted by: Oooo
Length of ownership:6 months
Bought the 40 cup for about 11 months ago I absolutely love it. I bought a bamboo wheeled platform to roll it back and forth on the counter makes it much more comfortable to move. I didn’t like the plastic spigot it leaked so I bought a stainless splgot it works great hope zero water would replace the plastic spigot with stainless steel I have encouraged family and friends to purchase zero water products
I would recommend this to a friend!
