WaterWell’s ultrafiltration technology was originally developed for people living in developing nations and for distribution in a humanitarian crisis.
Our ultrafilters filter up to 1000 liters of water - equal to 2000 plastic water bottles. The ultrafilters are compatible for both our 700ml travel water bottle and 500ml foldable water bottle.
WaterWell can filter out particles to 0.1micron whereas most of the filter bottles on the market only filter to 0.2 microns. This gives you cleaner, safer, and healthier drinking water.
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. 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 flow rate increases with each use as the water penetrate each layer of the filter. This means unlike iodine purification tablets, there’s no aftertaste.
Official testing results for WaterWell filters
The results for the filtration system within WaterWell has been independently tested against internationally recognized standards by industry specialists in the USA, Europe, and India; all have confirmed that the filters in the WaterWell bottles eliminate over 99.9% of harmful contaminants in water.
The SGS microbiology test results verify that particles to 0.1 microns can be removed at a rate of 99.9%. The test results meet EPA standards which are the Gold Standard for Environmental Protection around the World and it identifies contaminants to regulate in drinking water. The Agency sets regulatory limits for the amounts of certain contaminants in water provided by public water systems. These contaminant standards are required by the Safe Drinking Water Act (SDWA).
SGS (Société Générale de Surveillance) is internationally recognized for it's inspection, verification, testing and certification.
Things To Keep In Mind:
WaterWell filters are intended to remove contamination from water. Therefore, they will not be able to effectively filter additives such as isotonic powders, rehydration tablets, cordials, juices etc.
While the filter removes 99.9% of parasites and bacteria, it cannot filter salt water as the salt is chemically bonded to the water molecules. This includes urine, which also has a high salt content.
The filter removes 99% of chlorine for up 500 liters of tap water. However, it cannot filter fluoride.
