A lightweight and compact filter that connects to any 28mm water bottle or flask. The Inline Filter can also be incorporated into a HydraPak bladder system.
Hydrapak says:
Access potable water anywhere. Our unique and versatile 28MM inline filter threads directly onto popular 28MM opening bottles and flasks and is equally easy to install in any of our reservoirs and caps with a Plug-N-Play™ connect system. This versatile connectivity makes our filter a great backcountry water treatment solution whether you are squeezing your water from a Stow into another bottle, gravity filtering your water out of a Seeker or Pioneer water storage bag or filtering as you drink on the go from a Stow or HydraPak reservoir.
Our Verdict
This filter’s stand-out feature is that if you incorporate it with any Plug-n-play compatible water bladder, such as the Contour Hydration Reservoir. This means you can fill your bladder from a stream, attach the filter and off you go; you don’t need to sit around processing water.
This also means you can use the system as a gravity filtration set-up when you are at camp, adding to the versatility of this setup. Of course, you can use the filter attached to a standard bottle as you would with any other 28mm filter, so you have three set-up options to suit your needs all in one filter.
The HydraPak 28mm comes with an adapter to back flush the device on the go; it is one extra thing to carry that I could potentially lose. Personally, I prefer not to have to carry any additional kit.
If you use a bladder, it's really hard not to recommend this system.
