Top Questions:

Q
How is ZeroWater® Different?
A
  • It is a 5 stage filter which is more comprehensive than conventional 2 stage filters
  • Ion Exchange Technology as opposed to simple carbon only
  • Removes virtually all (99.6%) detectable dissolved solids while leading brands removes up to 50%
Q
How long will the filter last?
Q
Does the TDS Meter measure lead levels?
A

No, the meter measures Total Dissolved Solids and is not intended to measure lead levels.

Q
What's considered an acceptable level of lead on my water?
A

The EPA has established a maximum threshold of 15 ppb for lead content in tap water. ZeroWater® filtration is certified to meet these requirements.

Q
Do ZeroWater® products contain BPA?
A

No, all ZeroWater® products are BPA-Free.

Q
What is the meter reading?
A

The TDS meter included provides a reading of total dissolved solids in Parts Per Million, ppm.

Q
What are total dissolved solids?
A

Total Dissolved Solids (TDS) are non-organic impurities found in water, which contribute to a difference in the taste of water. Dissolved solids enter our water supply through old piping, run-off from road salts, pesticides, fertilizers and more.

Q
How fast should my water filter through a ZeroWater® device?
A

The filtration will be slower than conventional 2-stage filters because its 5-stage filtration works much harder to remove more contaminants.

Q
Does ZeroWater® reduce the pH of water?
A

Once the filter reaches end of life, you may experience an acidic or slightly fishy smell/taste in the water. As indicated in our instructions, once the digital meter reaches 006 or the light indicator lights up (depending on which was included in your device) you should discontinue the use of the expired filter and replace it. Our filtration has an end of life indication whereas standard filters do not. Continued use of the filter, after it expires, will only further deteriorate the ion beads and a reduction in pH may occur. The reduction in pH is not dangerous but there is a chance under extreme filter exhaustion that the pH levels may be reduced low enough to where you will experience a taste difference in the water, occurring at a meter reading below 1 or 2. We cannot determine if the filter failed prematurely as we have no indication of your tap water quality (all water is different and we have no way of knowing the specific properties in everyone’s water) nor your daily water consumption. Since the quality of tap water varies the reduction in pH, when your filter has reached the point of exhaustion, can vary as well.

How Does it Work?

Q

A
  • It is a 5 stage filter which is more comprehensive than conventional 2 stage filters
  • Ion Exchange Technology as opposed to simple carbon only
  • Removes virtually all (99.6%) detectable dissolved solids while leading brands removes up to 50%
Q
How does ZeroWater® Work?
A

The ZeroWater® Ion Exchange Filter consist of 5 stages that combine patented technologies to removes organic and inorganic contaminants in the water, providing the only filtered water that meets the FDA definition of purified bottled water.

Q
Do we have a full house or a faucet system? Do we make a filter for the fridge?
A

We do not offer a full house or faucet system due to our gravity fed technology.

Q
Water already filtered at municipality - why do I need ZeroWater®?
A

Even if a municipality were able to clean water to the extent that ZeroWater® does, the water can pick up chemicals on its way from the treatment plant to the faucet, which gives tap water that typical taste. ZeroWater® tastes crisp and refreshing.

Q
I have well water. Do I need your system?
A

If you have well water, it is the owner's responsibility to have the well inspected and tested for a variety of substances including microbiological contaminants. Once the well has been approved for drinking, ZeroWater® works with well water the same way it does with any other tap water.

Q
ZeroWater® vs. bottled water quality
A

ZeroWater® filters produce the only filtered water that meets the FDA definition for TDS in purified bottled water. So you get purified-quality water without the plastic bottles or the high cost. ZeroWater® unit can cost as little as 50 cents per gallon to have purified-quality water.

Q
ZeroWater® vs. Reverse Osmosis (RO)
A

ZeroWater® filters produce water that is a similar purity level to that produced from an RO system. Our systems also don't waste any water and operate based on gravity. In addition, they do not need to be installed into your plumbing.

Q
ZeroWater® vs. Distilled water
A

Distilled water involves the process of boiling the water, transferring the steam to another container were the vapors are condensed and everything that doesn't evaporate will remain in the first container. Impurities that evaporate will be in the water in the second container. While ZeroWater uses the process of deionization which involves filtering the water. The ion exchange beads in the filter takes the ions or minerals out of the water. People usually say that distilled water can taste flat whereas ZeroWater is described as crisp and refreshing. Distillation also requires electricity and takes hours to treat water.

Q
Pets/people need distilled for health reasons - is this the same quality?
A

Our water gives you the same quality as distilled, without the electricity or hassle of transporting the water home from the store.

Q
Microbiological/bacteria - Reverse Osmosis vs. ZeroWater®
A

Unless your RO unit is specifically designed for bacteria with a UV light or an ozone generator, for example, your RO membrane will quickly be filled with a bacteria biofilm if you have a bacteria problem. The ZeroWater® systems currently sold do not have the capability to remove bacteria.

What does it remove?

Q
Is it bad to remove all TDS?
A

Todays' filtering technologies cannot discriminate between bad chemicals and good minerals that could be present in the water, the filter removes all of these. Many nutritionists recommend that you receive essential vitamins and minerals from a well-balanced diet, and not necessarily from water alone.

Q
Lead?
A

ZeroWater® is certified by the NSF to reduce lead below the standards as set by the EPA (15 ppb). ZeroWater® is the only gravity fed pour through device certified to reduce both Lead and Chromium-6.

Q
Pharmaceuticals from tap water?
A

ZeroWater® filters have been independently tested to reduce pharmaceuticals from your tap water.

Q
PVC?
A

PVC is a type of plastic and doesn't leach out of the plastic into our system. ZeroWater® has passed a leach test, coupled with our 5-stage filtration there can’t be any plastic particles in our water.

Q
Fluoride?
A

Our filters have been independently tested by an EPA certified lab for the reduction of fluoride with an overall reduction percentage of 99%.

Q
Uranium?
A

ZeroWater® filters have materials commonly used in the industry to treat uranium. ZeroWater® filters have not been tested due to the high levels of uranium required for testing.

Q
Arsenic?
A

Our filters have been independently tested by an EPA certified lab for the reduction of arsenic with an overall reduction percentage of 99%.

Q
Chloramine?
A

ZeroWater® filters have been independently tested to reduce Chloramine. However, the presence of chloramine can reduce the expected life of the filter, so if you have chloramine in your water, you may need to change your filter more often than normal.

Q
Phenol?
A

At this point ZeroWater® filters have not been tested for the removal of phenol.

Q
Cryptosporidium?
A

At this point ZeroWater® filters have not been tested for the removal of cryptosporidium (microbiological cysts).

Q
Bacteria?
A

The current system is meant to be used with municipally treated, potable water as the current filter will not remove microbiological contaminants.

Q
Oxygen from water?
A

The filters do not remove dissolved oxygen from water.

Q
Chromium 6?
A

Yes ZeroWater filters are NSF certified to reduce Chromium 6 by 99.7%

Troubleshooting

Q
Why can't I get a zero reading with my Pitcher?
A

In order to get a perfect 000, there must be a complete seal when the filter is screwed in to prevent any contamination. Ensure that the filter is threaded correctly (watch for cross-threading) and that the blue filter gasket is fully seated up against the water reservoir. If your filter has a black gasket, confirm that the black rubber gasket is present between the filter and reservoir and has not gotten stuck in any of the threads.

Q
Why does my filtered water taste acidic or fishy?
A

When the filtered water tastes acidic or fishy the filter has reached the point of exhaustion and must be replaced. Filter life varies per household - it depends on your household water consumption and the amount of TDS (total dissolved solids) in your tap water (water chemistry varies by source and how it’s treated locally by your town or municipality). Please refer to the chart (under the question how long will my filter last) on the FAQ page to determine how many gallons you will get per filter. It is important that you periodically test your filtered water with your water quality meter and when the meter reads 006 or higher the filter should be replaced.

Q
The water is coming out black or gray. What's wrong?
A

Some brand new filters can let fine carbon particles into the water due to the way they've settled. This is completely safe and can be fixed by flushing the system until the water is clear.

Q
My brand new filter was wet / condensation was present in the plastic bag.
A

The content inside the filter is rinsed with purified water before it is packed. Sometimes, this can cause condensation inside the bag/lid, which is harmless.

Q
Flow Rate: Takes long to filter.
A

The water travels through 5 stages in order to bring your water down to 000. Most other filters are only 1-2 stages which is why their water can't reach 000. The slow flow of the water lets you know that the water is properly passing through each stage.

Q
Other: Soaking filter
A

Unlike other popular filters, our filters do not need to be soaked. However, it is a good idea to pour a few cups through to be sure your water is clear and reading 000.

Q
Pitchers: Pitcher faucet/spout leaking
A

Sorry to hear of the issue with your pitcher/dispenser. Please contact our Customer Service team at 800-503-2939, option 2, so we can work with you to resolve this issue.

Q
Why is my TDS Meter/Indicator not working?
A

Digital Meter ‐ Press the on/off button if the LCD screen shows no reading then the batteries may need to be replaced. Remove the end of the meter and replace with (2) 357A or (2) LR44.

Light Indicator ‐ If you have a light indicator submerge about one inch into tap water (not filtered ZW). If it does not light up, the battery is probably dead. If you have a Light Indicator with an on/off button, repeat the same steps as you push and hold the on/off button while submerged. To replace the battery, remove the end of the meter/indicator and replace with (3) AG3.

Q
Bottles/Decanter/Cooler: Mold or algae in bottle or decanter
A

Just like any other appliance, our products need occasional cleaning. First, clean out the item, paying special attention to any spigots, spouts or small creases or parts. There are many surfaces there that can harbor stuff that will grow. Be sure your water doesn't sit in direct sunlight. When handling our products and filters, please be sure you thoroughly wash your hands so you don't transfer any bacteria into the water. Be sure you thoroughly clean all parts to ensure the product is ready for re-use.

Q
My cooler is leaking.
A
  • How much water are you putting in the bottle? If the bottom part is full, you cannot add more water since the white divider ring is not water-tight. Even if the bottom is half full, you cannot completely fill the top since there is not enough empty space in the bottom.
  • If the above instructions do not work please try the following and test your float valve.

To test your float valve remove the top portion of the bottle and white divider ring. Lift the bottom portion of the bottle placing your hand under the round float valve and push it up gently towards the bottle (this will close the float valve). If it is still leaking after that please contact us for a replacement.

Q
I am not getting a 000 TDS reading from my cooler.
A

First, please review the troubleshooting in your owner's manual. Secondly, the company has made some improvements and has changed the color of the filter adapter from white to a translucent blue color to differentiate the two. The filter adapter is the piece connecting 3 circles where both filters thread into. Lastly, if you have a white filter adapter please contact customer service for a replacement adapter.

Q
How do I clean out my cooler?
A

Clean the reservoir and spigots by mixing 1 tablespoon of baking soda into 1 gallon of hot water and pouring the solution directly into the cooler reservoir. Let the solution sit for about 30 minutes and then drain through spigots and drain plug. Then flush the cooler with 3 gallons of plain hot water using the same method.

Q
Cooler water is not getting cold or hot.
A

You will have to refer to your manufacturer's instruction manual to fix this problem. If you need additional support please contact customer service.

Q
Does ZeroWater reduce the pH of water?
A

Once the filter reaches end of life, you may experience an acidic or slightly fishy smell/taste in the water. As indicated in our instructions, once the digital meter reaches 006 or the light indicator lights up (depending on which was included in your device) you should discontinue the use of the expired filter and replace it. Our filtration has an end of life indication whereas standard filters do not.

Filtration / Filter Life

Q
How long will the filter last?
Q
When do I change the filters?
A

Filter life varies per household. The filter life depends on the amount of TDS (total dissolved solids) in your unfiltered water and household water consumption (water chemistry varies by source and how it’s treated locally by your town or municipality). Please refer to the chart (under the question how long will my filter last) on the FAQ page to determine how many gallons you will get per filter. It is important that you periodically test your filtered water with your water quality meter and when the meter reads 006 or higher the filter should be replaced. It is strongly recommended that the reading not go past that point. Unlike conventional filters, you many notice a difference in taste or smell when the ZeroWater® filter has reached end of life. We highly recommend you change your filter at this point.

Q
ZeroWater® filters vs. other pitcher filters
A
  • It is a 5 stage filter which is more comprehensive than conventional 2 stage filters
  • Ion Exchange Technology as opposed to simple carbon only
  • Removes virtually all (99.6%) detectable dissolved solids while leading brands removes up to 50%
Q
Does well/spring water cause shorter filter life vs. "city" water?
A

The life of the filter depends on the TDS going in, not whether your water is from a well, a spring, or a municipality. Before using your well water with our system, be sure to have it tested.

Q
Does bacteria build up in the filter?
A

The ZeroWater® system contains specific materials which inhibit the growth of bacteria within the cartridge.

Q
What type of plastic is used in ZeroWater® products?

FULL LISTING OF DISSOLVED SOLIDS WE REMOVE FROM YOUR WATER

Q
What are total dissolved solids?
A

Total Dissolved Solids (TDS) are non-organic impurities found in water, which contribute to a difference in the taste of water. Dissolved solids enter our water supply through old piping, run-off from road salts, pesticides, fertilizers and more.

Q
Is it bad to remove all TDS?
A

Todays filtering technologies cannot discriminate between bad chemicals and good minerals that could be present in the water, the filter removes all of these, therefore it is important to follow a diet that provides these essential minerals that the body needs. Many nutritionist recommend drinking purified water with a meal and not in an empty stomach.

Q
How often should I measure the TDS level in my water?
A

The TDS meter that comes with your system is provided so that you can measure your TDS on an ongoing basis - perhaps every other day. This is especially important if you have high TDS water (over 300), as your filter will need to be changed more often. By using the TDS meter to frequently measure your filtered water, you will know it is time for a filter change before it has gone too far past 006

Q
What type of batteries does the meter use?
A

They take either 2 - 357A, 2-LR44 or 3-AG3 batteries which can be found anywhere you would buy a watch battery.

Q
What can't the meter detect?
A

The meter cannot detect uncharged particles such as organic contaminants. It also cannot detect undissolved particles such as bacteria.

Q
Why is my TDS Meter/Indicator not working?
A

As with any electronic device, sometimes you may encounter issues with the TDS meter.

Please follow the steps below to resolve your issue.

  1. Did you remove the cap? (Applicable for digital only)
  2. Have you turned it on? (Applicable for digital only)
  3. Have you been storing it in the fridge? If so, sometimes you need to allow it warm up to room temperature so that it can function properly. If you have already done that, check to be sure it hasn't shorted out due to water contact.
  4. Please check the LCD screen to see if you see rust. If rust is present you will need to replace the TDS meter.
  5. If nothing else is wrong, the battery is probably dead. To replace the battery, remove the end of the TDS and replace with a new 357-A battery that you can buy anywhere you get a watch battery.
Q
Do TDS levels change in hot or cold water from the same tap?
A

TDS levels change in hot or cold water from the same tap because containments dissolve easily in warmer water which leads to a higher reading. The TDS meter corrects for temperature, but if the water is too hot it will give artificially high values. In general, the most accurate reading will be at or near room temperature.

BPA Free

Q
Do ZeroWater® products contain BPA
A

No, all ZeroWater® products are BPA-free.

Q
What types of plastics are used in ZeroWater® filters/pitchers? (Are they BPA free?)
