WakiWaki Water Purifier Bottle Review

Do you filter your water whilst out in the hills?

Often when you are out in the hills there is plenty of water to be found in streams, lakes and ponds. In the higher mountains it’s usually safe to drink out of flowing streams but what about on the lower fells? Rather than take a risk it’s probably best to filter any water before drinking it. There’s plenty of choice when it comes to water filtering systems, a brand I’ve only just heard of is WakiWaki. Here I look at their Blue Purifier water bottle (also available in orange and purple)

The system comprises of a rigid plastic bottle with a 600ml capacity (if using the filter the capacity is reduced slightly) The lid has a pop up mouthpiece which clicks down and locks in place when not in use.

The lid unscrews completely allowing the wide mouthed bottle to be easily refilled. The bottle comes with a straw and a filter which are interchangeable meaning that it can be used in two ways; either as a standard bottle to drink water or juice using the straw, or as filtering device. Swapping between straw and filter is a very simple process that only takes a few seconds. The lid also houses a small compass although I wouldn’t rely on this for navigating!

I tested the blue bottle, orange and purple are also available.

Also supplied are a syringe to allow simple backwashing of the filter after use and a carabiner which can be used to attach the bottle to a rucksack. The filter is replaceable if you exceed its lifespan of filtering 1500 litres.

Personally I prefer to use soft-flask type filters when running or hiking and bladder systems when camping so I probably wouldn’t choose a rigid water bottle. However, for anyone who likes to use a rigid drinks bottle the WakiWaki offers good value. It is versatile in that it can be used simply as a drinks container or as a water filter. It will fit neatly into the side pocket of many walking rucksacks and is sturdy enough to cope with the usual knocks and scrapes that come with hill walking and camping.

For people simply wanting to drink from a source rather than carry and filter water then the WakiWaki Straw Filter would be a good option. https://www.gowakiwaki.com/product-category/outdoor-water-filter/straw-filter/
