- Rated 5 out of 5 stars4 weeks agoEasy. Quick. I love it.
I decided to try Mosi to see what it was all about. I bring it to work and take it home. Portability is great. I love it.
SSSueEllen S.NY, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoGreat little product!
Easy to use and clean. Super handy to keep at work.
KMKevin M.NC, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoA true masterpiece
Built with care and consideration, the post 21st century all in one Mosi Infuser makes a bold statement on how we drink and consume tea. With bold and eccentric craftsmanship, no other can compare to the Mosi Tea's all in one infuser. An absolute bold statement and built with the quality of a masterpiece.
SNSean N.NY, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoDont wait and buy it now!
Very pleased with the infuser. Well made, easy to clean, and brews a wonderful and tasty batch of tea. Am planning to order two more for family.
LBLarry B.NY, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoAll in One Infuser
Nice product. Easy to use. Wish it was twice as large and still fit into a car cup holder and keep the tea warmer a little longer.
JAJoseph A.IA, United StatesVerified BuyerWas this helpful? - Rated 4 out of 5 stars1 month agoCoffee and Tea infuser
I bought a pack of 4 infusers; they came in the wrong colors but customer service was great and the glitch in the processing system is being worked on... so thank you!
The product itself is going to work great for me when I travel and need to make tea or coffee on the go, which is why I bought these for my family. This is not going to be my every day coffee or tea drinking cup for 2 main reasons. First: the clasp is little cumbersome to open and close; I'm getting used to it but it's not an easy "click of a button" kinda thing, especially when driving. Maybe I'll get used to it a bit more as time goes but it's already taking me a while. Second, my drink doesn't stay hot for too long; maybe an hour, tops. Then it's just lukewarm. So, I will probably stick with my every day coffee mug that keeps it hot longer. HOWEVER, the main reason I bought these for myself and my family: TRAVEL. I think these will be great for when we are out somewhere without a coffee maker or a tea pot but have access to hot water... then we can steep our tea or brew our cofee ON THE GO... So, I'm giving it an overall 4/5. I hope this helps! Thanks for making this product.

P.S. The picture with my mosi flask (and coffee).

Recently got my all in one tea infuser and I love it. Can enjoy tea time, anytime. The quick release on cap is a nice touch
THTimothy H.WA, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoSo easy to use!
I love herbal tea and brewed cacao as a way to destress and curb my appetite between meals. But it can be kind of a hassle to make it, especially when it's loose leaf. My new infuser bottle makes it so much easier! I've had it for two days and I've already made myself many cups worth. I don't need to worry about what to do with the teabag, because it's an all-in-one closed system.
JWJoshua W.UT, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars2 months agoMosi made my life easier!
I got the all-in-one. I do Creo Bru (cacao tea) every morning and while traveling. I found that the large silver infuser works great for Creo Bru. I used to have to use an aeropress and would have to wash it before I leave the hotel room. That took so much time in the morning, but I loved the way it tasted. Now finding Mosi, it also tastes great and I don't have to rush to drink it before I go out of the house or hotel anymore. I can just take it with me. My only complaint is that it doesn't keep it as warm as I want it to.
JHJessica H.TX, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars2 months agoEasy brew
I love this tea infuser made easy😉
Been using it daily with the fine screen for my Yerba Mate & it makes a delightful brew!
Very convenient especially for taking on the road!
I need another since I left mine at a friends home !
KBKristine B.MI, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars3 months agoLove it!
I bought this as a gift for my son who loves this cup! It is perfect for him being on the go and easy for when he is home.
KAKaren A.CA, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars3 months agoExcited to use this at work!
I've been wanting to get into loose leaf tea for a while but didn't know where to start. Then I saw the Mosi commercial on Youtube and looked it up and saw there was a holiday deal, so I bought the all in one infuser set. I like the design, though I wish there were different size options for the infuser. I've only tried one attachment so far, but it works well. I've always been sensitive to hot temperatures, so it's nice that the double walled design lets me carry around the infuser without getting burned. I'm looking forward to bringing this to work along with a variety of loose leaf teas.

Frequently Asked Questions
-
How does the Mosi Tea Infuser work?
We designed the Mosi All-in-One Infuser Bottle to make brewing tea as easy as filling up your water bottle. Just add your tea leaves into the infuser, screw it into the bottle, pour in hot water, and flip it over to steep for the recommended brew time. Once it’s ready, sip directly from the bottle or pour it into a cup if you prefer. No need to remove the tea leaves—our design prevents over-steeping, so every sip tastes just right.
-
What makes the Mosi Tea Infuser different from other infusers?
When we set out to create the best travel-friendly tea infuser, we knew we needed something durable, functional, and designed specifically for tea lovers.
- Made for Everyday Use – Instead of glass, we chose BPA and BPS-free Tritan™ (the same material used in baby products and medical devices!), which is shatterproof, lightweight, and doesn’t absorb flavors or odors. You get the clarity of glass without worrying about it breaking.
- Patented Steeping System – We designed the first multi-attachment lid so you can brew loose leaf, matcha, coffee, cold brew, and really... anything! Unlike standard infuser bottles, our design ensures your tea doesn’t over-steep, so it tastes just as good on your last sip as it did on your first.
- Leakproof & Travel-Friendly – The bottle is completely sealed when closed, making it perfect for tossing in a bag without worrying about spills.
-
Can I use the Mosi Tea Infuser with any type of tea?
Yes, it’s designed to handle all loose-leaf teas, from delicate green teas to hearty oolongs. The fine-mesh infuser keeps even small tea particles contained while allowing full flavor extraction. You can also use it for fruit-infused water, cold brews, or herbal blends. And our matcha attachment (the first ever for a travel infuser) allows you to blend matcha perfectly without any tools or bowls. It truly allows you to brew anything, anywhere!
-
How do I clean my Mosi Tea Infuser?
We kept cleaning simple. The bottle easily disassembles so you can rinse out the infuser and bottle after each use. For a deeper clean, just pop it in the dishwasher (top rack recommended). If you ever notice tea stains, a little baking soda and warm water will take care of them.
-
What is the warranty or return policy for the Mosi Tea Infuser?
We want you to love your infuser bottle, and if you don’t, you can return it within 30 days for a refund or exchange. If anything isn’t working the way it should, let us know, and we’ll make it right.
