A simple but effective filtration step for cleaner, safer water on the go, the SteriPen Pre-Filter removes particulates through a durable 40x40 micron screen before UV purification — making it especially useful for cloudy or sediment-laden water where UV treatment alone is less effective. Designed for seamless integration with any SteriPen UV Water Purifier, the two-step process is straightforward: pour water through the filter to fill your bottle, swap in the SteriPen, flip and agitate until treatment is complete. Steripen Water Bottle Pre-Filter Features Durable 40x40 micron screen filter cartridge removes particulates from both clear and cloudy water Designed for seamless use with SteriPen UV Water Purifiers for a complete two-step purification process Simple process — filter, insert SteriPen, flip, and agitate until treatment indicator confirms completion Suitable for solo use on the go Lightweight and portable for trail, travel, and emergency use TECH SPECS Weight: 29g Dimensions: 5.1 x 7.6 cm
