Where can the water filter straw be used?

Use the water filter straw for drinking from rivers, streams, lakes and other fresh water sources. Travel, backpacking, mountaineering, camping, back country adventures, hiking, walking, survival, perfect for your emergency kit.

The water filter straw works by forcing water through microscopic holes in a medical grade membrane (the same kind used for kidney dialysis) preventing, bacteria, protozoa and other particles from passing into the tiny straws which then enable you to drink clean water. The coconut carbon and silver ions help remove heavy metals and bad tastes.

If viruses may be present you may wish to use a purifying tablet in the filtered water before you drink it.

1. Drink directly from the water source with or without the extension straw.
2. Attach to your HydraMate Foldable Bottle or any other standard 28mm screw top bottle.
3. Fill your HydraMate water bottle and squeeze into a clean container.
4. Attach to the end of your water bladder straw and drink normally

- Use the pre-filter attachment on the straw to remove large particles from the water before drinking

Simply blow into the water filter straw or flick to expel any remaining water and dirt particles.
No syringe needed. 

Do not use with salt water.
Do not use in hot water.
Do not freeze.
Always drink from the cleanest water you can find and take extra precautions where human or animal faeces may be in the water source.

It was fantastic!

I went on a 4 day wild camping trip in Scotland's national park and took it with me. It was straight forward to use and worked perfectly!Granted if you drink directly from a stream you have to suck quite hard to get something through, however, as I usually filled up the pouch and squeezed the water into another bottle, it worked just fine!Compass does not work properly but that did not really come as a surprise and didn't matter too much for me! As the straw is what I was after, I am giving it 5/5!

Very useful

Bought this for an attempt at running the Glyndwr Way with no overnight support. Topped water up from a stream and the water tasted fresh and no dodgy belly so all good

Hydramate straw and bag

Just used it on one trip so far and it seems of decent quality. Also get a decent flow rate when squeezing water from the bag which is included to fill up pans/bottles

HydraMate straw

Quality product, fast delivery. Amazing price! I have not used it yet, but will be tested in the black mountains soon!

Great Filter 👍

Have a similar filter but without the activated carbon element. Used the Hydramate once up to now and had clear water that tastes ... just like water . Would recommend . Great service from Swimcell too.
