Top Questions:
How is ZeroWater different from other brands?
- Advanced Filtration: While most conventional water filters use 2-stage filtration, ZeroWater employs a patented 5-stage filter systemSuperior Technology: ZeroWater filters utilize Ion Exchange Technology, unlike simple carbon-only filters
- Unmatched Purity: ZeroWater removes virtually all (99.6%) detectable dissolved solids, whereas leading brands remove only up to 50%
How long will the ZeroWater filter last?
When do I change the filter?
When the TDS meter reads "006", it's time to change the filter. It is strongly recommended that the reading not go past that point. Unlike conventional filters, ZeroWater will show a noticeable difference in taste or smell, indicating it’s reached the end of life
How often should I measure the TDS level in my water?
Use the provided TDS meter to regularly test your water, ideally every other day, especially if you have high TDS levels (over 300). 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
Do ZeroWater products contain BPA?
All ZeroWater products are BPA-Free
How fast should my water run through the filter?
Due to its comprehensive 5-stage filtration, water filtration is slightly slower but far more effective than 2-stage filters. It also depends on the TDS level of your water, for example our water has a TDS of 025 and our ZeroWater jug can filter 1.7L in approx. 20 minutes.
Does a ZeroWater filter reduce the pH of water?
ZeroWater doesn't change the pH levels of your water. Under extreme filter exhaustion, pH reduction may occur but is not harmful. It’s best to replace the filter upon exhaustion
Where can I recycle used ZeroWater filters?
Most Household Waste & Recycling Centres in the UK accept used filters for recycling. Filters should be disposed of in the plastic recycling skips and will then be reprocessed and turned into other products such as garden furniture. Please also check with your local authority first
Reasons to choose ZeroWater:
UK tap water is drinkable, so why do I need a ZeroWater filter?
Even well-treated tap water can pick up chemicals along its way from the treatment plant to the tap (or from pipework in your home). This is what gives tap water that typical taste. ZeroWater offers crisp, refreshing water by removing these contaminants

Is it bad to remove all TDS?
Current filtering technologies can’t distinguish between harmful chemicals and beneficial minerals, so it removes all of them. Many nutritionists recommend that you receive essential vitamins and minerals from a well-balanced diet, and not necessarily from water alone
ZeroWater vs. bottled water
ZeroWater filters deliver purified-quality water at as little as 10p per litre, without the plastic waste
ZeroWater vs. Reverse Osmosis (RO)
ZeroWater matches the purity of RO systems without the need for plumbing installation or water wastage
ZeroWater vs. Distilled water
Unlike the energy-intensive and lengthy process of distillation, ZeroWater uses Ion Exchange for crisp, refreshing water
Troubleshooting:
Flow rate: my filter/jug/dispenser takes too long to filter
The water travels through 5 stages in order to bring your water down to 000 TDS. Most other water filters use only 1-2 stages which is why their water can't reach 000. Slow flow indicates effective contaminant removal
Why can't I get a "zero" reading on my TDS meter?
Ensure the filter is threaded correctly and fully seated to prevent contamination. Check that the blue rubber O-ring is in place
Why is my TDS meter/indicator not working?
Press the on/off button. If the screen shows no reading, replace the batteries (2 x 357A or 2 x LR44)
Why does my filtered water taste acidic or fishy?
This taste indicates the filter has reached the point of exhaustion and must be replaced
My new filter arrived wet/with condensation in the bag
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
