Grayl Geopress Purifier

Author: Eric Deneault

As an outdoor enthusiast, I have had the pleasure of using the Grayl Geopress purifier on a backcountry Mountain goat hunt, back country archery elk hunt and also while guiding big game in western Montana. The Grayl Goepress purifier is hands down the best water filtration system I have ever used. It is the fastest and easiest filtration system for water that I have found, in just 8 seconds you have 24 ounces of water safe to drink all the way down to the virus level. On my backcountry mountain goat hunt I had two good friends join me on the adventure. They were both shocked and impressed on how well this product worked. Both of them now carry the Grayl Geopress with them in the field. After using this water filtration system I would highly recommend this product over any other.
