FAQS

Due to its 5-stage filtration system working much harder than conventional 2-stage filters, the filtration will be slightly slower although it removes more contaminants.

No, all Culligan ZeroWater® products are BPA-Free.

No, Culligan ZeroWater® does not change the pH levels of the water. Continued use of the filter, after it expires, will only 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. We highly recommend replacing your filter upon exhaustion and not attempting to overuse your filter.

Lead is generally not present in the wider public water supply network in the UK but may be present in houses built before 1970 that have lead pipework carrying the water around the house. The UK has a standard threshold of 10μg/l.

• Most conventional water filter jugs use 2 stage water filters whereas Culligan ZeroWater® water filter jugs use a patented FIVE stage filter.
• Culligan ZeroWater® filters use Ion Exchange Technology as opposed to a simple carbon only water filter.
• Culligan ZeroWater® filters remove virtually all (99.6%) of the detectable dissolved solids while leading brands remove only up to 50%.

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-offs from road salts, pesticides, fertilizers and more.

Culligan ZeroWater® filters and Jugs are made from BPA Free Polypropylene. Culligan ZeroWater® devices are made from BPA Free Polypropylene and ABS.

No, all Culligan ZeroWater® products are BPA-free.

The filtration technology is exactly the same as the pitchers, the tumbler is not certified at this time.

With the support of Culligan's research and expertise, we will continue to innovate and improve our products to meet your needs.

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

No, the Culligan ZeroWater® TDS Meter measures Total Dissolved Solids and is not intended to measure Lead levels.

Today's water 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.

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

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

• 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%

Culligan ZeroWater® filters are made of BPA Free Polypropylene Culligan ZeroWater® devices are made of BPA Free Polypropylene and ABS

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

When the TDS meter reads "006", the filters should be changed. It is strongly recommended that the reading not go past that point. Unlike conventional filters, you may notice a difference in taste or smell when the Culligan ZeroWater® filter has reached end of life. We highly recommend you change your filter at this point.

The Culligan 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 has as few Dissolved Solids as purified bottled water.

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 Culligan ZeroWater® systems currently sold do not have the capability to remove bacteria.

Even if the service provider were able to clean water to the extent that Culligan ZeroWater® does, the water can pick up chemicals on its way from the treatment plant to the tap or from pipework in your home, which gives tap water that typical taste. Culligan ZeroWater® tastes crisp and refreshing.

Culligan ZeroWater® water filters produce the only filtered water that meets the definition for TDS in purified bottled water. So you get purified-quality water without the plastic bottles or the high cost. Culligan ZeroWater® units can cost as little as 10p per litre to have purified-quality water.

Water softening systems exchange sodium or potassium with calcium to avoid calcium buildup and allow soaps to lather better. They are not meant to improve the taste of drinking water.

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, Culligan ZeroWater® works with well water the same way it does with any other tap water.

Culligan 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.

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

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 Culligan 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 Culligan ZeroWater is described as crisp and refreshing. Distillation also requires electricity and takes hours to treat water.

Unlike other popular water filters, our Culligan ZeroWater® water 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.

The water travels through 5 stages in order to bring your water down to 000. Most other water filters use 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.

In order to get a perfect 000, there must be a complete seal when the Culligan ZeroWater® water filter is screwed in to prevent any contamination. Ensure that the Culligan ZeroWater® water filter is threaded correctly (watch for cross-threading) and fully seated in the water reservoir. Confirm that the blue rubber O-ring is present between the Culligan ZeroWater® water filter and reservoir and has not gotten stuck in any of the threads.

No, Culligan ZeroWater® does not change the pH levels of the water. Continued use of the filter, after it expires, will only 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. We highly recommend replacing your filter upon exhaustion and not attempting to overuse your filter.

When the filtered water tastes acidic or fishy the Culligan ZeroWater® water filter has reached the point of exhaustion and must be replaced.

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

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

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

Culligan ZeroWater® filters and jugs 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.
