Hydrapak UltraFlask+ Filter Cap
Run fast, filter faster. The UltraFlask+ Filter Cap threads seamlessly onto all of HydraPak's 42mm running flasks and handhelds for a lightweight, straightforward filtration solution. Featuring a traditional bite valve and cap design, runners can drink freshly filtered water directly through the high-flow Blaster valve.
Fast and safe filtration is provided by the integrated filter of this UltraFlask+ cap. Easy to use, it removes Escherichia coli bacteria, Cryptosporidium parvum cysts and Giardia Lamblia from approximately 1,500 litres of water at a rate of >1L per minute. With its minimal design and lightweight materials, this filter is the ideal choice for runners, taking up no extra space when stored or threaded directly onto a flask. The easy-to-drink bite valve auto-seals after each sip to eliminate annoying drips causing distractions. Easily thread the filter onto your 42mm softflask, flexible bottle or water storage container for versatile filtration. Included is a backflush adapter. This plugs into the filter valve and threads onto a HydraPak Stow or bottle of clean water for backflushing the filter to restore its flow rate.
*Effectively removes common waterborne bacteria, such as E.coli (99.999%) and parasitic cysts (99.9999%) per HSF 42.
Care
Avoid freezing filter. Freezing may ruin the hollow fibre membrane. If in freezing conditions Hydrapak recommend you keep the filter in your pocket or near your body to prevent freezing.
