GRAYL UltraPress Replacement Purifier Cartridge - Black

The replacement filter will help with product longevety

Water tastes great!

As a water industry professional, I am fairly picky about my water treatment systems. I picked this one because it removes protazoa and viruses in addition to bacteria (most backpacking filters just remove bacteria, and are not necessarily safe unless you have pristine sources). The inclusion of the additional treatment systems is very reassuring and I have used this filter all over the world to produce safe drinking water from international taps and backcountry rivers (even muddy ones). My only complaint is it wears out much faster than the reported number of cycles. I can only use if for about one trip (up to 10 days) before it wears out. If you are trying to prolong the life of it between short trips, make sure you store it with all the parts separated so it can completely dry, or it will mold. For me though the cost of rebuying the filter for every trip is well worth the security of having clean drinking water where ever I go. I highly recommend this product, just wanted to be open about its limitations.

I Always keep an extra in my truck

Every hikers dream.

We travel internatinally alot and have used the Grayl for over 10yrs!! But we use it in the states also because often you find yourself in a hotel without water and dont wish to pay $5 a bottle! But you can use this in a stream out in the bush in a pinch its that good!! I always have two on hand, one for the grayl we are using and one in the package for when I need a new filter! Dont want to be caught without one! The price saves you tons of money in buying bottled water plus you dont have to drink from plastic which if the bottle sit on the sun or heat up anywhere or anytime bad stuff leaches into the water!! Its a win win! No I didnt get paid or get anything free! Genuinely love this product!!

Perfect

Love Grayl! Never travel without it! Im always super confident water is safe and tastes delicious! Includes travel is remote parts of Asia, Central America and Mexico. I only wish my container were larger and it was a bit easier to push to filter the water (my petite wrists take the staring a bit since I have to make the water so often). But I fully trust it and have never had a single illness due to water when using Grayl!

Mistakenly got wrong filter replacement sz because it was under suggested items purchased w. I got the 24oz Grayl so $130 and my extra filter is worthless now and can’t seem to find link for return
