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.

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.

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)

The water flow rate will never be the same as a normal bottle of water due to the nature of using an ultra 2 stage filter. However here's some tips to help improve the flow rate:

  1. Please soak the filter for 15 minutes prior to first use to prime the fibres and help reduce the potential after taste on the first 550-100ml of water that is consumed.
  2. Run clean water in reverse flow forcefully from the top to the bottom of the filter. After back flushing give it a few sharp shakes.
  3. Suck some clean water into the filter and back flush it 5 times and blow back the water five times.

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.

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

During the first several 100ml's you may experience some aftertaste this is quite normal and is derived from the carbon fibre. This should increasingly dissipate upon the first day of use.

In addition we recommend holding it under the tap and running water through it, or sucking some water up and then spitting it out. Any aftertaste should disappear soon after.

Also please note It should be soaked first before using to maximise its efficiency and lifespan, this will also help any aftertaste upon first use to dissipate. For first time usage, simply rinse the filter and bottle with clean water and stand the filter upright in water for a few minutes.

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.

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.

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!

The 700ml travel water bottle weighs 141 g.

The 500ml foldable water bottle weighs 82 g.

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.

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

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.

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

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.

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

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.

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.

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

The plastic outer case can be recycled and the inner filter medium can be treated as per normal organic waste.
