Does the filter come ready to use?

It should be soaked first before using to maximize its efficiency and lifespan. For first time usage, simply rinse the filter and bottle with clean water and stand the filter upright in water for 1 minute keeping the top 1cm dry. The filter flow rate will be slow at first but as the water penetrates the filter's fibers, the flow rate will improve.


How do I maintain the filter and how often should I clean it?

Please clean the filter and bottle as regularly as you would a normal bottle when you have access to clean water.

Or after a trip away and when you have access to clean water - please run clean water forcefully through the filter in reverse flow to drinking then shake it to dislodge any particulates and fully dry the filter before storing away. If you have the latest version of WaterWellthe filter can be cleaned by using the backflush device included. Fill the device with clean water and then dispense the water through the tip of the filter in reverse flow to drinking 2-3 times.

And finally if your trip is for an extended period of time.  Suck some water through the filter and regularly blow back through the filter to clean the filter and prevent clogging.

How does the filter work?

The ultrafilter eliminates up to 99.9% of waterborne pathogens and can filter any fresh water source.

The filter has two stages of filtration:

Stage 1. It uses carbon fiber, which is a super quick and efficient adsorption material. It strongly removes any unpleasant odors and tastes in water.

In contrast, most water filters only use activated carbon blocks or granulated activated carbon as a filter medium. However, once all of the adsorption points are filled, contaminated water can be released.

There are no carbon fines found in the WaterWell carbon fiber filter so secondary contamination is eliminated.​

Stage 2: The 0.1-micron ultrafiltration membrane (hollow fiber) is a highly efficient method of filtration and requires no chemicals. it’s 99.9% effective against bacteria protozoa and cysts (the average size of bacteria is 0.5micron)


Does it use chemicals?

The filtration method uses particle filtration and does this means unlike iodine purification tablets, there’s no aftertaste.

How do I know when the filter needs to be replaced?

The bottle's auto shutdown feature lets you know when the filter straw needs to be replaced. This also prevents you from drinking contaminated water.

You can purchase replacement filters here.


Does the filter remove fluoride  and chlorine? 

WaterWell filters remove 99% of chlorine for 500 litres of tap water however they do not remove fluoride- the only way to remove fluoride from water is to use reverse-osmosis, activated alumina or ion exchange. Please be careful if you purchase filters that employ these last two methods. Filters using low grade powdered activated alumina have the potential to leach aluminium into your drinking water and domestic ion exchange filters have a low retention rate and could release high concentrations of fluoride un-expectantly into your output water.


How much money would I save using this water filter bottle?

Each filter can filter up to 1000  of water, equal to over 2000 disposable plastic water bottles. So the travel water bottle with  would cost $31 for the first year. Each additional year would only cost $21 a year for the replacement filter.

Assuming that an average  bottle costs $1, that would cost you $2000 a year for 1000 litres of water. So by using the WaterWell filter water bottle, you would be saving $2000 a year. 


How does the WaterWell Filter bottle reduce waste?

By choosing to use WaterWell products you’re helping to reduce plastic waste and protect the environment. Every year, we produce billions of plastic waste, which harms the marine wildlife and ecosystem. It takes anywhere from 400 to 1000 years for plastic to break down, which means that every plastic bottle ever produced (unless destroyed) will be around long after the day you die.

In addition, vast quantities of oil, water, and other valuable resources are needed to produce and ship bottled drinking water.

One WaterWell filter filters up to 1000 liters of water, equal to 2000 disposable plastic drinking water bottles. By using our filters, you will be drastically cutting down on plastic waste, pollution, and costs!


How much does the water bottle weigh?

The 700ml travel water bottle weighs 141 g.

The 500ml foldable water bottle weighs 82 g.


What is BPA and why is it bad?

BPA stands for bisphenol A which is an industrial chemical that is commonly used to make plastics, such as water bottles. Research has shown exposure to BPA can pose health risks, which includes negative effects on the brain, behavior, blood pressure, and prostate gland of fetuses, infants, and children All WaterWell bottles are BPA free.

Are WaterWell products BPA free?

Yes, all of WaterWell products are 100% BPA free for your health and safety.

Can other liquids be used with the filter bottle?

WaterWell filters are intended to remove contamination from water. Filters will become inefficient if used with additives such as isotonic powders, rehydration tablets, cordials, juices etc.

Can it filter sea water?

While the filter removes 99.9% of parasites and bacteria, it cannot remove salt as it's chemically bonded to the water molecules.


Can it filter pool water?

No it cannot. Activated carbon is very effective in removing free chlorine from tap water however the concentration of free chlorine added to pool compared to municipal tap water is considerably higher.  Although these filters are highly effective removing chlorine from tap water, the high concentration of free chlorine from pool water would block the absorption sites in the carbon fibre too rapidly, compromising the effectiveness of the filter for filtering out the total chlorine. 


Can it filter urine?

No, it cannot filter urine since urine typically high in salt.


What is the pore size of the filter?

Our updated increased specification filters bacteria and parasites to a size of 0.1 microns - bacterial cells are typically 0.5 microns in size. This eliminates up to 99.9% of waterborne pathogens and ensures clean healthy drinking water.


Can I wash the bottle in the dishwasher?

The 700 ml travel water bottle is dishwasher safe. The filter straw can be removed and the bottle sanitised in the dishwasher or with boiling water. Please be-careful is using boiling water for sanitising the bottle.  

However, the foldable water bottle can not withstand sanitisation in a dishwasher and boiling water. It can be cleaned with warm water, soap and pipe cleaner. 


Can I keep my bottle in the refrigerator?

Yes, WaterWell bottles can be safely kept in the fridge.


Can I keep my bottle in the freezer?

No, you shouldn’t keep your bottles in the freezer since the filter’s membrane can become frozen and damaged. In the event that your filter is frozen, please replace it as soon as possible.

Does Waterwell filter cryptosporidium

WaterWell has a 0.1 micron filter and is concerned with the particle filtration of waterborne bacteria, parasites and cysts. Most bacteria cells are between 0.2 to 10 microns. Most cryptosporidia are 3–6 microns in size so will be filtered out by WaterWell


Does this filter out micro plastics?

Yes WaterWell filters all particles at 0.1 microns and above. 
EFSA defines microplastic as particles ranging in size from 0.1 micrometers (microns) to 5 millimeters.

Can WaterWell filter viruses?

WaterWell cannot filter viruses. If you’re worried that there could be a viral risk where you’re going, we would advise to use with water that has been purified using reverse osmosis , chemicals, boiling or UV  purified water and use WaterWell as a secondary filter to remove particulate sand sediment ( it’s important to note that these methods do not remove sediment and particulates in the water)

What Water sources can I use WaterWell with?

Please note It’s best to use WaterWell with with municipal tap water and pure flowing natural water sources (but not down stream of any effluent waste water sources, such as chemical factory run off, sewage etc. ) Please note WaterWell does not filter dissolved salts (sea water), pool water, chemicals, minerals, viruses or heavy metals.

Does WaterWell remove Chlorine?

WaterWell filters have a chlorine removal rate of 99% up to 500 litres and a 85% removal rate of chlorine after 500 -800 Litres of tap water. In relation to carbon fibre filtration please note that the WaterWell filter is not just for tap water filtration, it can be used for natural fresh water (not containing chlorine). Depending upon the ratioof fresh water water sources to tap water sources used -the filter has the capacity to filter 1000 Litres.

Does WaterWell filter out the good minerals?

WaterWell does not filter out the beneficial minerals like iron, calcium, magnesium and bicarbonate because they are dissolved in the water and are at the molecular size so the particle filtration will not be effective for these substances. 

Do you drink with the bottle in the upright position, as though using a normal straw? 

When drinking from the bottle it is not necessary to tip the bottle because you're drinking through a filter straw which draws water from the bottom of the bottle 

Why is there a small hole in the lid?

The small vent is a design feature to help displace the water with air when drinking. 
Upon opening the mouth piece the small hole becomes uncovered and could only leak water if tipping the bottle upside down.  When drinking from the bottle it is not necessary to tip the bottle because you're drinking through a filter straw which draws water from the bottom of the bottle
