One Bottle. Four-Stages Of Filtration. Every bottle includes our premium 4-Stage Ultrafiltration Filter, combining multiple filtration technologies to improve water quality with every sip. Stage 1 – Medical Grade PP Cotton Captures larger particles including sand, rust, dirt and sediment before they reach the main filtration media. Stage 2 – Coconut Shell Activated Carbon Helps reduce chlorine, unpleasant tastes and odours, leaving water tasting cleaner, fresher and more enjoyable to drink. Stage 3 – Medical Grade PP Cotton Provides an additional layer of fine particle filtration, supporting consistent water flow and enhanced filtration performance. Stage 4 – Hollow Fibre Ultrafiltration Membrane Advanced hollow fibre technology physically filters microscopic contaminants. Independent laboratory testing demonstrated a 99.99% reduction of E. coli under laboratory conditions. Together, these four filtration stages work to provide cleaner, fresher-tasting water with every refill. (Recommended replacement every 3 months for this filter, to maintain optimal performance.)
