(Compatible With Pristine Flow 1.0 Bottle) Heavy-Duty Filtration for Outdoor & High-Sediment Water Built for tougher water conditions, the Ahlstrom Water Filter Cartridge is designed to handle what everyday filters can’t. Whether you’re filtering outdoor water, travel water, or visibly dirty sources, this cartridge delivers powerful filtration you can rely on. How It Cleans Your Water The Ahlstrom filter uses a dense, layered fiber filtration media designed to physically trap sediment, dirt, rust, and larger particulate contaminants. As water passes through the tightly packed fibers, impurities are captured while clean water continues through the cartridge. This structure makes it especially effective for murky or untreated water, where sediment load is higher and filtration demands are greater. What It’s Made Of High - performance Ahlstrom filtration filament Multi layered depth filtration with activated carbon fiber Engineered for the tougher water sources Best For Untreated or questionable water sources Outdoor use (camping, hiking, travel, outdoor water sources) Water with visible sediment or debris Emergency or backup filtration Because of its heavy-duty filtration density, the Ahlstrom filter requires slightly more effort when drinking — a natural trade-off for enhanced contaminant removal. Replacement Schedule For maximum filtration performance and the cleanest water possible, we recommend you replace the filter every 2 months. Instructions before use Please ensure you soak our filter cartridges a good 6 minutes in normal cool water to properly allow the filament to perform at it's best. Naturally the filter will remain wet for it's lifespan duration so long as you are using the bottle to drink from.
