Reviews

Quality Product

"Got the replacement filter for two older Grayl water purifier bottle. I ordered the the one way rubber insert on both. I like the option of being able to mix electrolytes:) This works great because it also allows easy filtration for cooking needs too!"

— Casey O. (5/5)

Replacement filter with valve.

"The replacement filter with valve that I recently received is not as efficient as the original products purchased. The valve does not work effectively, resulting in a small leak back into the water reservoir. I am unsure why, but it is inferior to the original product. I would like to include an observation that the customer service aspect of dealing with the replacement of a valve was not of a standard I thought the company would provide; it was distant, and a lack of communication, as well as information, was needed."

— Paul B. (2/5)

Great system with purifier and

"Great system with purifier and filter in one. The design has been improved since the first iteration of Grayl, making the removal and attachment of the filter easier. Only downside is the limited life and cost to replace the purifier cartridge."

— TIm M. (4/5)

"Couldnt be put together better. Amazing"

— John (5/5)

Much easier filtration

"As always a brilliant replacement for my old filter that has lasted a very long time but I felt it time to replace as it was getting quite stiff to filter with."

— Alisdair S. (5/5)

Ultra press purifier cartridge

"With these grayl replacement cartridges you can rest assured that where ever you go you have safe, reliable great tasting water."

— Dave M. (5/5)

Safer than not filtering and reduces bottled water.

"Safer than not filtering and reduces buying bottled water. I haven’t tested all that it filters. I have used it sometimes at work when the water tastes funny, during boil water notices, and when hiking/backpacking. I do question on the purification part. I tested the water post filter with a TDS tester and the result is the same as tap water pre-filter. Not sure if that should be the case. I would still use and recommend the product with questionable waters. Especially if traveling in other countries."

— S L. (4/5)

The GOAT

"Best water bottle hands down. Eliminate plastic waste, filter water from tap or creek. This is a must have. Just ordered a Geopress for the wife!!"

— Noel W. (5/5)

Water taste better

"After researching many water filter and purifier methods, I find this filter to be the best for taking out viruses, bacteria, micro plastics, and helps to improve water taste. After getting sick in Mexico by drinking the water, I now take a Grayl with me wherever I go."

Q&A

Hello, I am looking to replace the cartridge in my ultrapress, about to purchase one here but just wondering is it as simple as unclipping and unscrewing the existing one, and then attaching a new, or do I need to retain any parts from the old cartridge? Thanks!: It's as simple as unlocking and removing the existing cartridge and then screwing on a new cartridge and clicking into the lock position.
I found my Ultrapress in the cupboard and it had water in it. The water may be years old. Is my filter cartridge still good? I cleaned everything off but didn’t want to mess with the cartridge.: Since your filters have been improperly stored for a significant amount of time, they will 100% need to be replaced.
Why are you charging extra for the one way valve when you previously said it would be included with a cartridge as a standard feature ?: Every Grayl purifier bottle purchased from grayl.com comes with the one way valve as a standard feature. However, there are a lot of Grayl bottles out in the wild that do not yet have this feature, that is why we offer the valve as a standalone item, so other users can upgrade their existing bottles.
Will pre-filtering water with hollow membrane filter positively affect this cartridge rated lifespan and if so, than how many additional cycles could be expected?: Pre-filtering is a great way to preserve the lifespan of a Grayl purifier cartridge, but the maximum lifespan cannot be extended.
Why can the replacement filter not come as just a "filter" which can be fitted into the plastic housing? It's such a waste of plastic everytime you need a new filter. I want a filter bottle to save plastic waste, not make more.: Our current technology simply cannot be designed to work that way while still proving effective against protection of ALL waterborne pathogens (bacteria, protozoa, virus).
