Drinkable water doesn’t always taste great. If you like to add a little flavour or electrolytes to your filtered water, this little one-way valve lets you do just that, without compromising your Grayl’s filter. Tucking perfectly into the center of the filter, this valve lets clean water flow through to your favourite drink mix, without letting any of the drink mix flow back into the filter.
