Our ultrafiltration stage uses a hollow fiber membrane with an incredibly fine 0.1-micron pore size, that’s 500 times smaller than the width of a human hair. Think of it as a microscopic sieve that lets clean water through while physically blocking out 99.9% of harmful bacteria, protozoa, parasites, microplastics and cysts. All without the need for chemicals.

Most bacteria are around 0.5 microns, so this membrane forms a powerful protective barrier, ideal for travel and outdoor adventures where water quality can be uncertain.

💡 Bonus: These ultrathin fibers allow dissolved beneficial minerals to pass through, so you stay hydrated and nourished.

Unlike typical filters that use loose carbon granules or fines, WaterWell features an activated carbon fibre block, a highly effective and fast-acting filtration medium.

This activated carbon block not only improves taste and removes unpleasant odours, but it also significantly reduces chlorine, heavy metals, pesticides, some forever chemicals (PFAS) and volatile organic compounds, commonly found in water sources.

Because it's a solid block (not loose carbon), there's no risk of secondary contamination when the filter becomes saturated, a known issue with conventional carbon filters.

The result? Cleaner, better-tasting water without compromise.
