How to Choose Your ZeroWater Filter and Replacement Filter

How to Choose Your ZeroWater Filter and Replacement Filter

To choose your ZeroWater filter and replacement filters, you need to keep these following things in mind-


Daily Usage

To know what kind of water filter you need, you should always first analyze the amount of water that you use. If you live by yourself, and only drink a maximum of 8 glasses per day, then a filter dispensing 30 cups a day might be a bit too ambitious option for you.

A pitcher might suit your needs most and also be convenient to use.Similarly, if you live in a large joint family, a filter which does not produce as much output as it is being used in a day, will practically have no worth.

Therefore, your best choice here would be to use the ZeroWater 23 or 30 cup dispenser. It is also a great office filter if you want to use it for employees in a common space.



Make sure that the filter can be transferred in need and is not too heavy, no matter what the size. Pitchers do not have this problem as they are typically quite light.

But large dispensers are going to be heavy, so make sure that you are getting something you can move easily from room to room.Again, if you are choosing a large dispenser and are concerned with the outlook of the filter, buy one that matches the appliances of the room you are going to put in.

Pitchers will not have this problem as they are smaller in size and do not typically need to match their surroundings.



Make sure to have an idea about how much you are willing to spend on a filter beforehand. After analyzing the usage, size, and body of the filter, choose the one that is within your budget but also suits all your needs.


Maintenance Cost

While buying the filter, always keep the maintenance cost in mind too. While this might seem a small thing, buying a large dispenser only for yourself that you have to keep maintaining, might cause you more loss than good.

ZeroWater Reviews FAQs

Here we have some of the most commonly asked queries regarding ZeroWater filters:

1. How is the ZeroWater filter different?

All softeners are similarly programmed, so if you learn to do it once, it will be easier from next time. But it can be difficult to learn if you don’t have enough knowledge of it. But seeing how it’s done and following the guidelines can help you do it yourself.

2. What does the water quality meter measure?

The water quality meter measures the amount of total dissolved liquids in the water. These liquids are responsible for altering the taste of the water.

3. How long does it take to filter water?

Since ZeroWater filters use a 5-stage purification process, the time to filter the water is longer than the average time used by filters.

4. How to clean a ZeroWater filter?

Wash with normal water and soap.

5. Which one should I purchase?

Which ZeroWater filter you should purchase depends on a number of factors, including size, budget, water usage, maintenance cost, etc. Consider all these before making a purchasing decision.

6. Does ZeroWater lessen the pH of water?

When the filter reaches the level of the end of life, you may experience little fishy smell or taste or acidic in the water.

When the digital meter touches 006, or the light indicator lights up, you have to suspend the exercise of the old filter and set up another one.

We have a filter comes with indication though some top branded filters do not. If the date expires, it is better not to use the filter.

When the filter expires the date, there is the possibility of a reduction in pH level and deteriorate the ion beads.

The lessening of pH level is not dangerous, but there is the possibility of filter exhaustion. When the pH goes low enough to where you can experience a different taste of water, happening at meter shows reading below 1 or 3.

We are not sure since we have a signal of tap water quality or our everyday water consumption. As the standard of water varies for the reduction of pH level when the filter goes to the point of exhaustion may vary also.

7. Why is my TDS not working well?

Digital Meter ‐ When LCD monitor shows no reading, press the off or on the button. Batteries are needed to be replaced in some cases. Take out the end of the meter and then replace with (2) 357A or (2) LR44.

Light Indicator ‐ If the light indicator under one inch of the tap water, it may not light up. The reason is that the battery is dead. Since you have a light indicator with off and on the button, do the same step since you press and hold them off and on the button, while flooded. To change the battery, take out the meter or indicator and replace with AG3.

Final Words & Recommendation

Now that you have read our ZeroWater reviews, you can choose which one you want to buy for yourself easily. We would recommend you to buy the 23 cup dispenser, as it is great for both small and large households and does not need to be refilled too frequently.
