Replacement Lid Compatible with Cirkul Water Bottle | Fits Flavor Cartridges | BPA Free, Leak Proof, and Dishwasher Safe (Black)

I’ve had this for about a week now and use it daily, all day. I like it. It doesn’t leak, doesn’t whistle, and fits my hydro flask like a glove. I’ve never owned the name brand of this, but this cap doesn’t seem to have any issues with using the name brand cartridges. Bought a second one for my son as he kept trying to take mine and he’s happy too. Worth the money!!

Tried to get Cirkul to replace the faulty air inlet valve on my Cirkul bottle. They offered suggestions to get the valve working but none of them worked. I purchased this cap to replace the cap on the Cirkul bottle. It fits perfectly, has NO leaks and works GREAT with the Cirkul cartridges. While I am a little disappointed with Cirkul's response to my issue with the failed air inlet valve, this cap brought the Cirkul bottle back to excellent condition.

A great replacement for Cirkul 22 ounce cup. Materia is durable and seals well to prevent leakage. The size is perfect.

Works great with the Cirkul bottle and flavors. I like the larger handle on this one. The plastic feels more durable also.

If your original Cirkul lid is getting grungy, or you just want to use your flavor cartridges with a different, better bottle (like a Hydroflask or Iron Flask!), this Chill Oasis replacement lid is basically a secret weapon. It does everything the original lid does—fits the flavor cartridges perfectly—but it adds a ton of versatility. It’s a great, simple swap. Why It’s a Smart Buy Flawless Flavor Cartridge Fit: This is the most important part. The lid is specifically engineered to accommodate your Cirkul Sip cartridges, so you can enjoy flavored water without any hassle. Leak-Proof Confidence: It comes with a high-grade silicone gasket to lock everything down. Toss your bottle in your gym bag or backpack without worrying about spills during travel or workouts. Universal Wide-Mouth Compatibility: This lid is the ultimate multitasker. It works with standard Cirkul bottles, but customers also confirm it fits other popular wide-mouth bottles like Hydroflask and Iron Flask. This is a huge bonus if you want to use those cartridges with a bottle you already own! Easy Cleanup: It’s made from BPA-free plastic and food-grade silicone, and both the lid and cap are dishwasher safe. It even includes removable gaskets so you can get into all the nooks and crannies for a truly hygienic clean. Heads Up Some customers find the price a little high for just a lid, but if you factor in the money saved by not having to buy a whole new bottle or the ability to use your expensive cartridges with better-insulated bottles, it usually evens out. It is designed for wide-mouth bottles, so it won't work with narrower or non-standard openings. Final Verdict: For Cirkul users, this is an excellent, high-quality replacement or upgrade. It keeps your drinks contained, is easy to wash, and the fact that you can use it to make other popular bottles Cirkul-compatible makes it one of the most useful bottle accessories out there. It’s an effective and affordable fix that performs just like the original—maybe even better.

The lid that came with my Cirkul bottle whistled like crazy every time I drank from it, no matter what. This replacement is silent, fits perfectly, and even looks better.

This is perfect, it fits on my big mouth tumbler

It was a decent alternative to buying a cirkul water bottle when you already got a bottle at home. Works well with my hydro flask. Here’s to chugging more water!

Fits my 40oz stainless water bottle perfectly.. totally addicted to Cirkul now
