GRAYL 500-CMP UltraPress 500 ml (16.9 FL oz) Drinking Water Filter Bottle ? Water Filter for Outdoor Hiking, Camping, Survival and Travel, Camp Black, One Size

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.

Feel safe with this, never worry about my water - expensive but peace of mind well worth it. Saves having to carry loads of water in, I also take a platypus bladder to store extra water direct from the water source to filter when I get to camp through the grayl. Brilliant,

Debería de haber uno en cada hogar.Filtra perfectamente. Lo regalamos a unos amigos que viajaban a Sumatra y fue un acierto,cogían el agua del río y la filtraban para beber.

Bought for multi peak hikes in the Mourne Mountains where we have plenty of fresh water sources to top up. Lightens the load when out on summer day hikes and gives us that peace of mind that we won't run out of water or get sick from drinking fresh mountain water. Love the colours choices. Bought one for my husband and one for myself.

Se purifica muy rápido sin tanto esfuerzo, me gusta que el filtro es intercambiable y la botella ligera para no sumar más peso en los viajes de larga caminata

The bottle arrived without a lid, rendering it useless. Had to return it. I subsequently bought one from a retail store and found it to do everything I'd hoped. Would have rated it 5+ stars if it had have been shipped with lid/cap.
