GRAYLUltraPress 473 ml (16 oz) Drinking Water Filter Bottle Water Filter for Outdoor Hiking, Camping, Survival and Travel Coyote Brown

Long review but I get into details on why you need to buy one of these. Please read on.I’ve had a grayl since the kickstarter days. I love these things for travel all over the globe but I didn’t grab mine when I came to Dubai a couple years ago because a friend needed to “borrow” it for a trip to Africa. Well after getting here and setting up my home filtration system of a Sawyer filter to a Zero Water filter (for bacteria and microbes and then heavy metal’s / solids) I decided I needed something for on the go and set my sights back to the grayl. It gets me better water, cheaper.For those that aren’t into water filtration allow me to explain. The tap water in Dubai by testing is actually drinkable, however the construction of the buildings from what I’ve seen has lead to varying amounts of metallic compounds to be in the water here. This coupled with pipes being in old buildings possibly being covered in gunk that allows bacteria to breed is what causes the majority of water related illnesses. To prevent this two types of filtration needs to occur, bacterial / viral and then heavy metal’s and other solid contaminants. The grayl does both of this in a portable bottle, getting that combination in a household setup requires 2 separate filters in a gravity system.Now you may ask why I went through all of this when I could just buy bottled water. Well this is where math comes into play. For the grayl ultra press I can make 150l of water or 300 bottles at 500ml. If I go downstairs it’s between 1 AED to 1.50 AED for a single 500ml bottle. Buying the grayl and using it until the filter is completely gone is the es cat same price as buying the 300 bottles at 1 AED per bottle, it saves 150 AED if I pay 1.50AED per bottle. Now if I decide to go to one of the theme parks, water parks, or staycation on the palm where 500ml bottles of water are 10-20 AED I get my return in as fast as 30 refills at 10 AED per bottle. Additionally the replacement cartridges are around 100 AED per cartridge which means that the same 300 bottles at 1 AED now averages 200 AED in savings.It also massively reduces single use plastic going into the environment. Being able to fill up at any sink in the UAE also never puts me out of reach of water when I need it. I know this has been a long review so I thank you for hanging tough and finishing my breakdown. Hopefully someone can translate it to Arabic.

J'ai utilisé cette bouteille a plusieurs reprise dans des rivieres et lacs et je n'ai jamais été malade ! Très bon achat.

I use this bottle on camping and hiking expeditions. It was so easy to use and worked very well. No sickness or stomach aches after using. Clean and quick source of water. I used it to filter water from water streams and lakes and worked like a charm. Great product, highly recommend it.

Overall solid quality and it seems to filter well (purely subjective as I didn’t do any water quality tests). Easy to use -separate the inner from outer container, fill the outside, loosen the cap on the inner, and then push the inside container down into the water filled litter container. If you use your body weight to push its easy. I used this to fill my other water bottles that were larger - took a few minutes but easy to do. My only suggestion is that the fill line should be in a high contrast color to see where to fill the water up to. The loop / hook on the top is fine to use to attach to a bag. The rubber grip on the bottom is a good add - keeps it from sliding around on wet rocks. Didn’t leak in my bag.

Che dire, si è già detto tutto su questa borraccia. È spettacolare!! Possiedo anche la Geopress, "quella di dimensioni maggiori", ma devo dire che questa è assai più maneggevole e facile da riporre. Peccato solo per l'assenza del dispositivo di ritenuta del tappo. E che ci voleva a farlo??? Per tutti gli appassionati di bushcraft, trekking e avventura in genere è un must. Straconsigliata!!!!

Es excelente los materiales se sienten y son muy resistentes y cumple su función perfectamente, super sorprendido
