- Rated 5 out of 5 stars6 days agoLove it!
I wanted to give up coffee cuz I put too much sugar in it I saw these advertised and my coworker drinks tea too and it's such a hassle to get tea ready for work so I bought us each one and we are loving them.
SPShelli P.MN, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars2 weeks agoLove it
I just recently got this and I'm not disappointed, my first use was tea for waiting in my car in the school pickup line. I made it before I headed out the door let it seep on the drive to the school when I arrived I just sat back and enjoyed my tea while waiting for my grandkids. The tea stays hot for a very long time and the infuser is very easy to set up and use. I love it.

Legit process for steeping strolling and sipping
ASAaron S.VA, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars3 weeks agoOn the go tea.
I really enjoy my Mosi tea bottle with infuser. It brews a proper cup of tea, that I can also travel with. It fits perfectly in my day pack for hiking and is great for my work commute as well. Zero leaks so far, durable construction and a great lid. The drinking spout is well designed and truly allows you to enjoy your tea.
DMDustin M.WA, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoNice product!
Is really interesting and fun product this is my first time trying out after receiving it and so far I really it… I learned a few things using it for first time but I will be absolutely using this on regular basis and of course I will be promoting and recommending this product!
KDKatherine D.CA, United StatesVerified BuyerWas this helpful? - Rated 4 out of 5 stars1 month agoThese are not stain resistant.
I have the mint color and it’s really stained. I love the product , I just don’t like how badly it’s stained.
MBMaria B.CA, United StatesVerified ReviewerWas this helpful? - Rated 5 out of 5 stars1 month agoUseful and pretty
I love being able to have loose leaf tea on the go without worrying about over steeping it. It's attractive and dishwasher safe! I do wish there was a bigger option. But otherwise, it doesn't leak, it steeps nicely and i love that you can smell the tea as you sip it.
SSSue S.AL, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoGetting Through My Tea Collection!
In recent years, I have built up a collection of teas. I liked the thought of drinking all of these teas, but the usual equipment did not give me what I needed to get through the collection. The Mosi Tea Infuser is easy and fun to use and is helping me make the most of my collection of teas!
EAErik A.CA, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars1 month agoPerfect for our current travels!
Touring around visiting various relatives, a good fresh brewed “cuppa” with my custom blends of Darjeeling, green, or oolong. Quick and easy to brew, and lightweight to pack. Great consistent brews! Love it. I have a pair now, usually rotate.
TTTres T.TX, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars2 months agoRV convenient
I'm in favor of anything that saves space and makes living in a Class C motorhome convenient, like my new Mosi Tea Infuser. All the pieces fit together when in use and for storage, so no hunting for a mug and infuser, or figuring out where to put that dripping wet infuser when you are done brewing. And it brews a nice cup of tea, hot or cold. It is not as insulating as vacumn sealed, double walled stainless steel. I don't have an opinion about durability or value, yet, but I'm enjoying it everyday.
SSSuzanne S.WA, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars2 months agoExactly What I was Looking For
I needed a bottle to steep my tea while I was out and about. I did a lot of research, and could not find exactly what I was looking for until I found Mosi. I got it less than a week ago in the mail and have already used it more than 6 times. It is now my go-to for my early morning tea as I run out the door for work. It is perfect for steeping my tea on the go! It is also easy to clean, which I appreciate.
LBLeah B.NC, United StatesVerified BuyerWas this helpful? - Rated 5 out of 5 stars2 months agoHOT STUFF!
I love my Mosi Tea bottle. Talk about keeping your fresh tea hot - watch out! Super easy to use and take with me when I run out the house. I also enjoy it while traveling, makes it easier to enjoy my favorite tea.

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.
