As someone who impulse-buys a can of probiotic soda or flavored seltzer from the bodega nearly every other day, “sparkling water on the go” seems like a no-brainer ask. Yes, there are no lack of status-y insulated bottles you can fill with your own seltzer — but man. Yawn. What if you don’t have that kind of foresight, and the seltzer thirst strikes when you’re out and about in the world?
This need to create the perfect portable seltzer maker has led to a couple creations over the past couple years: there are certainly bottles that have been designed to keep your already-carbonated drinks fizzy for longer, like Sodastream’s Fizz & Go Cool Bottle, or the Ninja Thirsti Travel Bottle (both of which only work with their respective carbonator appliances, and you still have to make it at home first before hitting the road). We spotted buzzy newcomer Roam SodaTop bottle on the show floor at CES this year, which promised not only a sparkling water maker in a bottle, but flavored cartridges too (unfortunately, like most CES darlings, it is still currently in development). The closest we’ve gotten before is the Aerflo System, but you have to buy into the cartridges and use the propriety bottle.
And therein lies the problem — people have a deep attachment to their tumblers. The Stanley cup is known as the internet’s “emotional support water bottle” for a reason, but Owala and even Hydro Flask have long held their status as well. Thankfully, now you won’t have to give up your water bottle in sacrifice of fizzy perfection, because Aerflo has a new gadget that attaches to a Hydro Flask lid and turns your boring bottle of tap into delicious seltzer.
A godsend for bubbly bevvy lovers everywhere, Aerflo for Hydro Flask makes sparking water with your existing bottle, and we’re shocked that no one has thought of doing this before. Just fill your Standard Mouth Hydro Flask (18, 21, or 24 oz) with cold water, then add a refillable CO2 capsule to the Aerflo top (the magic’s in the cap). Tap to spritz and vent, then rapidly shake to carbonate your water, and you’ve got a delicious sparkling drink ready to sip. Available at Aerflo.co now, this attachment accomplishes what many AI-bloated kitchen tech fails to do: offer a solid, simple gizmo for everyday enjoyment.
The Hydro Flask’s vacuum insulation actually helps out to keep the water as carbonated as possible, while also keeping it cold. It removes the need for bulky countertop appliances, and is a more lightweight and compact alternative to sparkling water-making bottles. This makes it a pretty sustainable option, but if you’re still worried about waste, Aerflo’s Capsule Exchange Service eliminates single-use waste by allowing you to send back your capsules to be refilled (each capsule makes four bottles of bubbly, respectively).
It’s the same old water bottle you know and love, only better, so find out how to turn your Hydro Flask into a pocket-sized soda water maker at Aerflo.co. Need bottle recs? Pick up one of our favorite Hydro Flasks below.
