Fabric:

  • For international travel and outdoor use, upgrade the Grayl Stainless-Steel Water Filtration Cup to a purifier with a G3+ purifier cartridge (sold separately)
  • G3+ filter cartridge is intended to reduce impurities that make tap water taste and smell bad, like chlorine, certain industrial and pharmaceutical chemicals and heavy metals
  • G3+ purifier cartridge eliminates everything the filter does, plus 99.999% of bacteria, viruses and cysts, including E. Coli, giardia, cryptosporidium and hepatitis A
  • Filters 16 fl. oz. in about 15 sec.

A very different kind of water filter

I've owned 6 or 8 water filters and this isn't like any of them. It isn't for ultralight campers, but it's definitely worth considering if you're in the market for a filter.

Two downsides: First - it's kind of heavy. For instance, I think the lid is really cool (it makes a little 'click' when you close it) but a different design certainly would have been lighter. But hey, it's stainless steel, which isn't light, and the unit feels bulletproof. Second - It takes some force to operate - my 9 year old isn't strong enough to use it, but my 12 year old is.

On the positive side, it filters really fast - 16oz or so in about 14 sec (with the 'filter' on). With the 'purifier', which you have to buy separately, it's slower and takes some force - about 20-30 seconds - but that's about a liter per minute, which is pretty good.

The coolest thing is the way it works - sort of like a coffee press. You pull the two sections apart, fill the outside cup, push the inner part down into the outer and water flows through as the two parts become one (not sure I explained that well).

The result is clean water, in a closed container, that you can drink or share - I don't think any other filter does this. (With the my bottles, you carrying around dirty water until you squeeze, with the pumps, you need a separate bottle. UV lights don't 'filter', really).

I think Grayl is right for international travel, day hikes and road trips (fits in my cup holder!). And I've actually been using it around the house, which is a first for a water filter (other than my brita pitcher).

So, after 2 days, I really like it.

Why didn't I think of this

I bought the Grayl for my wife. Before getting a Grayl she would us other popular reusable water bottles while at work and on trips but would complain about the taste of water in some of the office buildings she would go to. The Grayl is so easy to use and works so well she is free to get water from any office or hotel sink. If you are tired of drinking funny tasting tap water you need to get one of these.

Won't leave home without it.

This is the best product for travelers since the headlamp. You will never have to worry about bad tasting water again, you will never have to throw away a plastic bottle again, and you will stay hydrated longer. It is easy to use, easy to clean and worth every penny. I travel to Baja a lot and will always take this with me, I have no problem drinking the local water.

Never using plastic again!

So excited to receive this product and it held up to my expectations!! Easy to use, clean, sharp, perfect water. I couldn't believe how good the water tasted! You have to press with a little strength but that's how you know it works. Going to be purchasing many more.
