Q: What material is the straw made of? Is it glass, stainless steel, silicone or plastic? Is it replaceable?

submitted by MBDaines - 1 year 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 - 1 year 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 - 1 year 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 - 1 year 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 - 1 year 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

    Not for me

    This is a great idea and would be wonderful for travel. It’s a good qualify item but I didn’t like having to suck so hard to get the water through the straw.

    Where's the straw?

    Just received my Lifestraw tumbler. I have so many Lifestraw products and love them all. BUT I saw where you can drink something other then water if you take the filter out. How do I do that if there is not straw to get to the bottom liquid? Can it us a regular straw? I don't feel like that would be long enough.

    Love it!

    I just started using this and I love it. The water quality at work is questionable at best, and this has been a life saver. The first use, took a little more work to pull the water from the straw, but not it’s great!

    Good, but could be so much better

    Treated myself to the tumbler because I love the company and wanted to try something new. Love the colors/look, the stainless steel and the purifier straw features and that’s why it’s not 1 star. However, the cons are just too hard to overlook. My biggest issues with the tumbler is that there’s no airflow so when the lid is on all the way it gets harder to drink out of the tumbler because you just create a vacuum seal effect the more you drink. It’s really difficult to open the tumbler when you need more, which is often because the filter is big and takes away from the volume of water you can fit inside the tumbler, but the lid is silicone and is a push/pull on and off instead of a threaded lid which amplifies the vacuum seal pressure issue. On the bright side I guess it’s hard to spill when it’s that tight lol. Would love to see an upgraded version of these tumblers where it’s actually easy to drink out of them.

    Delicate and Straw needs to be longer.

    The water bottle broke when dropped, need to replace lid and straw connector. Also, the other bottle is deeper than the filter straw goes, so even though there’s 1/4 of water in the bottle, you still need to refill. A little annoying.

    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

    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. ”

    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!!

    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
