Q: What material is the straw made of? Is it glass, stainless steel, silicone or plastic? Is it replaceable?
submitted by MBDaines - 6 months ago
A: That's a great question! The LifeStraw 18oz Go Series Tumbler straw is made of BPA-free plastic. Yes, it is replaceable — the Go Series tumblers are designed to work with LifeStraw Go Series filters and are available for purchase separately.

Q: Are there any plastics on the inside? For instance, it looks like the filter is plastic. The only material listed is stainless steel. Which parts, if any, are plastic?
submitted by Doebrina - 6 months ago
A: Thanks for your question! The LifeStraw 18oz Go Series Tumbler is designed with a durable stainless steel body, which is the primary material you see listed in the product description. However, some internal components, including the filter housing and parts of the lid, are made from BPA-free plastic. This is common in water filtration products to ensure functionality, durability, and a secure fit for the filter elements.

Q: Can you wash this in the dishwasher?
submitted by John - 6 months ago
A: We recommended washing your LifeStraw Go Series bottle or tumbler by hand but if needed, the Go Series bottles can be placed in the dishwasher for cleaning, but only after the filters are removed and you should avoid the heated dry setting. It is recommended to remove the cover and mouthpiece from the main cap for bottles and wash them separately. It is recommended to remove the drinking straw from the lid for tumblers and wash them separately.

Q: Since the carbon filter ony lasts about 2 months, can it be replaced?
submitted by Grandma - 6 months ago
A: Hi, Yes, the Go Series bottles and tumbler all use replaceable carbon filters. You can find them on our website in a couple of ways: Visit the product page for the Tumbler, then scroll down just below the “Add to Cart” button. You’ll see a link that says “Add a Replacement Filter”—clicking that will take you directly to the replacement filters. Or, you can go straight to this link: LifeStraw Carbon Capsules – 2-Pack. I hope this helps! Let me know if you have any other questions.

Q: How long does the filter last our additional filters available for purchase?
submitted by Ali - 6 months ago
A: The Go Series Membrane Microfilter lasts up to 4,000 L or 1,000 gallons. The carbon filter should be replaced every 2 months or about 26 gallons. You can find both filters on our website under Shop/ Replacement Filters, then choose compatible with Go Series on the left hand side column. You can also go to: https://lifestraw.com/collections/spare-parts?pf_t_compatible_with=LifeStraw+Go+Series

Great product!
My wife and I love the tumblers and straws we purchased. Only thing my wife said was to draw water out was more difficult because of the filter and worried she may get “smokers” wrinkles around the lips over time. Maybe life straw could make a easier draw filter that filters micro plastics only since we use bottle water or frigerator water into our life straw tumblers anyway we wouldn’t need bacteria and other vocs powerful filter

Simply its just too hard to suck, it made me hate drinking water because it feels like i'm sucking my lungs out every time i take a sip. . . just not really functional

Tumbler is a great idea. Needs larger capacity.
Tumbler is a great idea, but really needs to be larger capacity to be effective. 32-40 oz would be nice options.

Like It
Love the simple design. It does require stronger sucking to get the water through the “straw. ”

I love it! We have an older version of an individual bottle and this is so much nicer and easier to move water through!

Super convenient and great for filtering
[This review was collected as part of a promotion.] This product is amazing for my outdoor girlies. I am always hesitant to fill up water bottles in public places but this filters it so well. It also has the cutest dealing and color combos and it’s just so nice not to have to use a plastic water bottle that contributes to animal cruelty and micro plastics

Same LifeStraw quality we have come to expect!
Same lifestraw quality and design I’ve come to expect. I never got onto the water bottle fad before this - so I decided to give this one a try. I like the idea of filtering my water when I fill from random sources - like the gym fountains etc.

difficult to suck through straw
LIFESTRAW Tumbler It is well made but hard to suck water through straw. I also wish it came with an attached cap for straw.

Lifestraw 18 oz Tumbler
I love it! Would prefer 20 oz or more with a handle since it’s a tad slippery but love that it fits in my cup holder in our Tesla!!

Best Water Container
This is my absolute favorite water container. I bring it to yoga class, the gym, and along with me for errands. I love the feel and look of it too.

Great bottle
[This review was collected as part of a promotion.] This water bottle is very pretty and sturdy. I wish the straw was slightly softer, but it is easy to clean. It did take some getting used to using the filter as it made it more difficult to drink the water, but after two days of full use it’s better. The filter seems sturdy! Overall love to have this for travel

"I absolutely love this product – I highly recomme
[This review was collected as part of a promotion.] "I absolutely love this product – I highly recommend it! It truly purifies the water and gives it a fresh, clean taste. I use mine at the gym to refill from their already filtered source, especially after a sauna session. The bottle is durable, and the filter is on another level!"

Love this!
[This review was collected as part of a promotion.] First, I want to mention how much I love this color. I also like the capacity of the water, not too small not too big. This tumbler is awesome because it filters your water as you drink it, it’s like a portable water filter in a tumbler.

Multi use
[This review was collected as part of a promotion.] I love this tumbler. It's not just a cup but also a survival tool if needed. I'm in Florida and we get hurricane so have a way to have clean drink water in an emergency is a must and this filtration system makes it possible.

Amazing
[This review was collected as part of a promotion.] I love using this tumbler instead of a pitcher with a filter. It’s easy to take on the go, and makes the water from the tap taste amazing. I can’t wait to take this on my travels!

Sleek appearance
[This review was collected as part of a promotion.] Great product from lifestraw, looks like one of the popular trendy tumblers from other brands! Filter works great and gives me peace of mind when I’m out, but I wish there was a way to remind me when the filter needs to be replaced. I personally like my bottles to have a handle for ease of carrying too so hoping for that in the next version.

Very pretty but…
[This review was collected as part of a promotion.] I wanted to love this tumbler! The color is very pretty but it’s so heavy and the filter in the middle makes it hard to sip. I’m not sure if I would recommend, unless you really want your water and juices filtered.

Comprehensive filter, great size and durability!
[This review was collected as part of a promotion.] The bottle is the perfect size! Great for car travel or if you need to fit it in your backpack on a hike. The material is durable and insulates temperature very well. The filter is strong and filters out many different components, so you can drink from many different water sources. My understanding is that the filter lasts several years. I love the societal impact as well; for every purchase, a child in need receives safe water for a year! My only suggestion for improvement would be for a way to know when the filter needs to be replaced.
