WaterWell replacement filters are compatible with our 700ml travel water bottles and 500ml foldable water bottles. Each filter filters up to 1000 liters of water, which equals to 3000 disposable plastic drinking water bottles.
The ultrafilter eliminates 99.99% of waterborne pathogens, ensuring clean safe drinking water. Can be used with all fresh water sources including rivers, lakes, streams, groundwater and tap water.
The impure water is firstly drawn through a hollow fibre membrane to eliminate pathogens and a secondary carbon activated filter to remove any organic compounds and chemicals before drinking.
The flow rate increases with use as the water penetrates each layer of the filter. Unlike water purification tablets, there’s no need for iodine, so there’s zero aftertaste.
Auto shutdown feature prevents you from drinking contaminated water and indicates when the filter straw needs to be replaced.
Note: As with the nature of any ultrafilters the water flow rate will never be the same as a normal bottle of water.
The filter is not capable of filtering pool and seawater as the chlorine and sodium chloride bonds to the water molecules which are much smaller than bacteria and parasites. This filter only filters out solid particles anything over 0.1 microns in size- so sediment, bacteria, and parasites etc.
We offer Lifetime warranty for all our products. If your filter ever fails to work due to defects or malfunctions, we will replace or refund your order. No questions asked.
