Grayl Geopress Water Purifier

£79.95
The Grayl Geopress Water Purify is simply brilliant. It is a completely different type of filter as it does not require you pump or suck water through a filter you simply fill up the out vessel and then depress the filter part through the water rather like a Bodum type coffee press, this makes it the fastest system on the market today.

Unrivaled Ease, Speed & Convenience. No other portable purifier rivals the speed, simplicity and effectiveness of GEOPRESS. In eight seconds, it makes 24 ounces (710 ml) of safe, clean drinking water – anywhere in the world. Effective on all seven continents, you can tap into the world’s water sources and safely drink from sketchy spigots, hotel sinks, murky rivers, wells or lakes.

Goodbye Sawyer

I have been using the Sawyer mini filter for quite a while and found it a good product, though sometimes a little frustrating to use. Having bought the Grayl Geopress recently the Sawyer is now relegated to bottom of the rucksack backup status.

The Geopress is a superior product in all respects bar one, which I will mention at the end.

Build quality is exemplary. Though a moderately heavy product by water bottle standards, the ability to refill from any freshwater source means no more lugging excess water everywhere. This feels like a bottle that will still be going strong in. 10 years time.

In use this is simplicity itself. Remove inner container, fill to line, reinsert inner and press. Job done. But read the instructions (I know, not very manly) as they contain some useful info on the best technique for using this purifier.

At home (1st use) this bottle completely removed the chlorine smell and taste from tap water. Eager to see if it works outdoors I went to a pond in the local woods. Some very sorry looking water went into the outer container and some very acceptable water came out of the spout.

In use I will continue to use a Millbank bag to prefilter pond or other murky water sources, mainly to help preserve filter life, but clear water can go straight through it.

The one advantage the Sawyer has is filter life. With proper maintenance the Sawyer goes on indefinitely. The Geopress filter is rated for approx 250 litres and costs around £25 a time. That still makes it only 10 pence per litre, which is significantly cheaper than bottled water and much more convenient.
