Sawyer Tap Filter SP134, water filter for on a tap

This Sawyer Tap Filter Water Filter is ideal for travel, in an emergency or whenever clean drinking water doesn't just come out of the tap. The filter is easy to transport. It weighs just 113 grams and is 14 cm long. The filter can filter up to 2300 litres per day. Naturally you'll never need that much in a day, so a better way of measuring is that this filter lasts for 10 years! Keep in mind that these 10 years also apply if you don't use the filter much. This filter isn't suitable for backpackers or hikers, because it only filters water from a tap. You can't use it to filter water from lakes or rivers.
