Reviews

Peace of mind in mexico

"This bottle is great for peace of mind while traveling, bot just hiking. If you drink lots of water and hate wasting or lugging around water bottles while traveling this should be your go to solution. Im buying a second one already as my girlfriend stole my first one. My only comment would be for people with a weak grip strength removing the external sleeve to fill with water could be a bit difficult but for most people the grippy material on it is sufficient."

— Kieran O. (5/5)

Great quality and exactly as described

"I bought this as a gift, so I haven’t personally used it and can’t comment on its functionality. However, my first impression is very positive. It looks high-quality, well-made, and just as described. I’m very happy with the purchase."

— Mirjana K. (5/5)

Not arrived

"Great bit of kit but it has not been delivered. GLS say the attempted delivery but I was here all day and no sign. I am considering buying a bottle carrier and maybe upgrading to titanium but if I cannot receive items maybe I will look elsewhere."

— David N. (1/5)

Best tasting water!

"I love my Grayl water bottle and filter. As an avid hiking, it’s indispensable. It’s easy to use and lasts a long time. I even tried it in nasty tap water with great tasting water as a result. It is a great product!"

— Chris P. (5/5)

Good Filter

"It's pretty difficult to remove the existing filter from the Grayl bottle. But I am glad I have this backup and the filter itself gives me peace of mind that my water is clear of viruses."

— Elizabeth W. (4/5)

Great product

"Took this on my last backpacking trip and it was so convenient. Filters water way faster and easier than my Sawyer Squeeze. I also like that it helps with heavy metals since Colorado has lots of old mines and I'm never sure what might be contaminating the streams. My only issue with it is it's bulky and heavy, but I'll still take it with me anyway because you can't beat the convenience."

— Christopher M. (4/5)

Water security

"I first saw the Grayl filter on a YouTube channel about the government advice to store water. It is reassuring to know this will give me extra water over any bottled water I have managed to store."

— Rose W. (5/5)

Filter cartridge

"It is incredible that Grayl has figured out a way to filter and purify of water. Rapidly with a replaceable cartridge, I will definitely continue to use this product."

— James E. (5/5)

Grayl

"It is the best filter out there. It is small, portable and complete; easy to use. The obvious choice in water filters."

— John E. (5/5)

Great for travel!

"We originally bought the Grayl Geopress Purifier for our backpacking and camping trips. Lately, we've taken it on all our travels - whether in the US or out of the country. Having the Geopress saves us from having to buy expensive airport or hotel bottled waters. Wherever we go, we have access to good tasting, clean water! We decided to have an extra cartridge on hand since we've been using the purifier so much!"

— Dianne S. (5/5)

Q&A

How long can the same filter be used (daily) without risk of fouling?: Great question. However, there is no actual hard and fast rule. With that said, if used daily, a great habit to adopt would be to perform a complete cleaning and drying every 10-14 days.
Kann ich mit der Filterflasche bedenkenlos Leitungswasser in Südostasien trinken?: Yes, Grayl purifier bottles offer worldwide protection.
Hi, I live in Switzerland and have just realized that there are two different models available for the geopress purifier filters and I was wondering if they are both original parts. The one model is the one shown on your page where the openings for water are arranged in groups of 6 horizontal slits. In the other one the openings for water are arranged in groups of 3 vertical slits. I just don't want to pay for some cheap copy of your product which is labeled with grayl. Thank you for your help.: Thank you for reaching out, and great question. The filter with the vertical ventilation slits is a first generation filter, while the one with horizontal slits is second generation. They are functionally identical in every regard with the only difference being that the second generation filter is also compatible with the one way drink mix valve.
Do your filters also filter Cyanobacteria and their toxins?: They do not. Areas where cyanobacteria are present should be avoided when using your Grayl.
Is the inner press, top, and outer shell dishwasher safe?: All bottle components (besides for the filter), should be handwashed with warm water and soap.
