0.01 μm Ultra Filtration Portable Water Bottle - 4-Stage Filtered BPA-Free Reusable Water Bottle - for Survival,Hiking,Emergency,Camping and Backpacking

This is a great filtering water bottle. I haven’t used it hiking yet, but it works fantastic just trying it out at home. You have to suck on the straw a little more than normal in my opinion, but not so much it’s a deal breaker.

Really enjoy using it.

This is my second bottle. It seemed more reasonable to buy a new bottle rather than buy a filter which is nearly as expensive. That is my only critique of the bottle other than it is heavy

I bought this for my husband's trip to Vietnam. He gave it 5 stars 🌟. It filtered the water great, he said. The only negative is he had to suck hard to pull the water through the straw. Lol love this product!

This water bottle is great. It filters impurities and leaves the water tasting great (tastes like nothing at all, which to me tastes great!). The size is perfect; not too big to lug around but big enough for you to get your daily amount of water. I got the purple color and it matches that of the photo. I love that the filter lasts a long time. Apparently it can filter around 1500 liters of water, so about six months worth. Most water bottle filters only last 1-2 months, so this bottle has great bang for your buck.My only issue (and reason for 4 stars) is not anything to do with the bottle's performance, but rather a part that comes with it. At the top of the lid, beneath the foldable straw is a tiny silicone piece that is inserted into the air hole that allows water to come up the straw when sucked. It's purpose is to prevent leakage when the straw is folded closed. Unfortunately, that silicone piece has gone missing after having this bottle for a few months. I'm writing this review in hopes of getting the attention of customer service to replace this silicone insert, because I can't seem to figure out how to contact them directly. I may have gotten a spare part when I received the bottle, but at this point, months later, finding it is a lost cause. If anyone knows how to contact them, please let me know in the comment section of this review (if there is one, I hope).Apart from that, this bottle deserves more than five stars. It's a great buy, functions perfectly, is an ideal size and leaves water tasting fresh and clean. It's definitely helped me increase my daily water intake which is why I bought this bottle. Thanks Joypur!

Love the style, and design. Very sleek and modern. It does what it is supposed to do. Delicious, fresh, crisp water. Thank you! I wish the instructions (in the package and on the Amazon webpage) were a bit more clear on first time use, or included a tutorial video. I searched online, I couldn't find instructions of how to use this product. Other than that, I am highly satisfied. Thank you!

Great purchase. Had no problem with water in other countries. Great filter.

The filter comes loose while hiking. The water can bypass the filter. Don’t hike with water in it. Drink when you get to a water source.
