Product Description
Filter: Hardened Stainless Steel. Not a mesh screen.
Say goodbye to those mesh screen filters. This stainless steel filter was built specifically for cold brew. The 200-micron holes resist clogging and allow water to circulate more freely, resulting in a strong cup of coffee. Plus, the filter’s walls are sturdy and dent-resistant, so they won’t tear or fray like those mesh screens.
Food Grade Silicone Cap
The unique cap design keeps grounds sealed inside the filter, so you don’t risk them spilling into your coffee. It also works as a shock absorber to prevent rattling and protect the metal filter. The cap is made of food-grade silicone and is BPA free.
Extendable Silicone Base
The Rumble Go’s silicone base features 11 different height adjustments that extend the filter by up to 1.5″. This allows it to fit a wide range of popular 16-34oz wide-mouth bottles, so you can transform your favorite water bottle into a cold brew maker, or otherwise just repurpose an old bottle that might have fallen out of use.
Compatible with a Variety of Wide Mouth Bottles
Fits many of the leading wide-mouth water bottles and insulated bottles on the market.

✔ A TRULY PORTABLE COFFEE MAKER – Simply drop this lightweight 2.8oz Rumble Go filter into a compatible water bottle, and you’ve instantly transformed it into a portable cold brew coffee maker. The brewing process couldn’t be easier: just add coffee grounds to the filter and water to the bottle, then seal it up and give it a “rumble” (i.e. rotate bottle horizontally 2 times), and your coffee is now brewing! By morning, you’ll have cold brew coffee as good as the stuff the pros make.
✔ COLD-BREWING IS THE SIMPLEST WAY TO MAKE COFFEE OUTSIDE YOUR HOME – Now you can make coffee just about anywhere you go, since there’s no need for heat or electricity. With Rumble Go you can brew coffee whether you’re camping, picnicking, driving, traveling for work or relaxing at the beach. All you need are grounds, lukewarm water and time. Rumble Go takes portable to the extreme. No glass bottles to break. No disposable filters to forget. No fragile parts to protect. No gizmos to charge.
✔ UNIVERSAL DESIGN HAS AN EXTENDABLE BASE THAT FITS MANY 16-32OZ WIDE MOUTH WATER BOTTLES & INSULATED TUMBLERS – Rumble Go’s universal design features an extendable base that adjusts by up to 1.5” to allow it to fit many of the leading WIDE-mouth water bottle and insulated bottles on the market, so it is compatible with bottles made by Hydro Flask, Klean Kanteen, Nalgene, CamelBak, Fifty-Fifty, Mira, RTIC and more. See the compatibility list in the image gallery for more info and tips for measuring your own bottle.
✔ A FILTER DESIGNED FOR STRONGER COLD BREW COFFEE – Stainless steel filter was designed by cold brew experts to make professional-quality coffee. The 18/8 stainless steel filter features 200 micron holes, the ideal size for allowing water to circulate & optimal extraction to occur with coarse-ground coffee. It’s a radical improvement to those first-generation cold-brew kits with fine mesh or paper filters, which were originally designed for brewing hot coffee. You’ll taste the difference.
✔ DURABLE, ECO-FRIENDLY & DISHWASHER SAFE – The type 304 stainless steel filter is shockingly lightweight (2.8oz incl. cap + base) but sturdy & dent-resistant. The food-grade silicone cap & base are BPA-free and act as shock absorbers protecting your bottle & filter from dings during movement. Eco-conscious design means no disposable filters, no plastic parts and a very minimal packaging footprint. All 3 components can be easily separated for a quick rinse or washing by hand or in a dishwasher.

LOVE THIS – Daily use
Now that its cold, I’m drinking lots of tea. And I was tired of making single cups of with my small filter for loose leaf tea. This has solved the problem. I can use my large mouth water bottle easily (i have 4 of various sizes) and make all the tea I want and keep it hot in the double walled bottles. Will be getting more for gifts. It is also fairly easy to clean with both ends removable. Only issue is loose tea settles in bottom cap so does require scraping out when cleaning. So I might recommend at tab on the bottom cap so the filter can be used from either end.

Works well in my 36oz. Yeti bottle
First off, to correct some misconceptions mentioned by some reviewers – 200 mesh is finer than 100 mesh – this filter is very fine, but still feels sturdy.I don’t drink coffee, but use this to brew cacao (very tasty and healthy, you should try it). Instead of pouring cold water over it I have to use hot water for flavor extraction and it works very well when left to brew for several hours and purposely shaking it several time during the brewing process to release more of the cacao flavor and beneficial nutrients. The brewed cacao turnsout very good and so far it’s the least hassle methos of brewing cacao I have found – you just have to plan ahead and not be in a hurry.

making tea in a nalgene
I like making A LOT of tea at once, and it’s super convenient to make it in a nalgene bottle–it’s okay with hot water, easy to clean, easy to take with me, makes a WONDERFUL hot water bottle until it’s drinkable. Usually I just use bagged tea, but I really want something that will let me make fancy tea in my decidedly unfancy container. So I recognize that I’m already outside of the targeted design for this thing, and it’s just my first time using it, but there are already a couple of things I noticed:The bottom silicon bit doesn’t have any sort of drain holes. I suppose maybe they’d be too big and let grounds out in the case of coffee making? but it means the base stays filled with liquid even after you pull it out of the container. Probably just annoying when you’re making cold brew coffee, excitingly dangerous with the tea. There are certainly design alternatives they could have gone with for that, good luck not making a mess any temperature you use it at.The lid is small enough to fit into a nalgene bottle comfortably, but JUST. So pulling it back out is a bit of an adventure. you also have to push it all the way into the container to pour water over it (again, presumably less hazardous when it’s not boiling water, bit of an adventure when it was.). Holes in the lid to allow the water to go in there might be nice as well–even with cold water it’s definitely blocking most of the mouth of the bottle so you’d have to pour very slowly.bottom has a bit of little feet on the side that make it almost as big as the top, so pulling it out of the nalgene was also a bit scary like “am I pulling too hard, will this thing fall apart midprocess and make me really sad?” and so far (2x) it hasn’t, but you’re still going to want to be careful about taking it out of the tube.what i’d like to see if this was really designed for tea (or hot coffee I guess): a lip on the lid to allow it to hang from the top of the bottle instead of having to be stuck in there, drainage through the bottom. But it’s the first thing I’ve found that’s actually sized well enough to go into the nalgene in the first place, so it’s a start at least!(Also, i’m not a coffee drinker, but given that the base is hollow and apparently can be pushed up inside the tube for shorter bottles than mine (32 oz nalgene big mouth), the fact that it has measurements on the outside is confusing (because the amount the inside holds will depend on the height of the assembled tube?) , so probably people should not follow those especially at first.)

Easy and no waste.
This summer I have become dependent on cold brew coffee. I was just putting the grounds in a jar with water, and then 24 hours later filtering through a sieve and a coffee filter – like a savage! This lets me use the same jar, but I just yoink the Rumble Go out of the jar the next day. No more panicking about making sure that I have enough filters. And the Rumble Go empties easy into the compost bucket – very green. The Rumble Go will be paired with my Nalgene bottle for glamping this month. I may not have an expensive coffee house budget – but I have very fancy coffees!I make my cold coffee with a tsp of vanilla, a tsp of stevia and a glug of good oatmilk.

Reloading tea is messy
It’s handy for cleaning the top and the bottom come off. Doesn’t make noise shaking around in a water bottle/thermos. Over time the the silicon pieces don’t seal as well: the top will pop off very easily tea comes out the top and the bottom. It’s hard to shake the wet tea out of the tube with out making a mess. I ended up using a smaller popsicle-stick style infuser instead.

Amazing cold brew system
This cold brew system is great. Iâm using a 32 oz mason jar.Make sure you get the size Rumble you want. This âRumble GOâ is for 32 oz water bottles. I ended up also ordering the 64oz version for, you guessed it, making 64 oz batches.No problem, nothing wrong with an extra coffee device. But make sure your Rumble matches the container you plan on using.Go get one !

Do you travel and love good coffee? Then you need this!!!
This is by far my favorite way to make coffee on the road. It’ll take a couple times to get the strength right and that also depends on the size container you use. I use a wide mouth Nalgene bottle and it fits right inside the bottle with room for a Ziplock of coarse ground coffee. The double ended design makes it the easiest cleanup ever! Now I don’t have to find a Starbucks for a $5 cold brew or a nasty can full of sugar from a convenience store. I absolutely love it!

Grounds everwhere
I have tried this twice now, in a yeti with fine and corse ground coffee. This filter allows for coffee sediment to escape and basically creates a coffee ground infused brown liquid that is not drinkable. This was a waste of cash. Go buy an in fridge ice coffee filter and save your time and money with item. Would not buy this again
