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

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.

Fits the cirkul bottles perfectly. Great value

Great find! Works amazing!

This fits perfect on my standard mouth waterbottle. Great value for what you're paying and leak proof. It does whistle when I drink though due to the airflow hole being small. It's not that big of a deal though. It's amazing.

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 fits great with my son’s cirkul bottle! I threw his away so I had to find a replacement and this was perfect!

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!

I got this to replace my original Cirkul water bottle lid because there was mold in the deep crevices that I could not wash out. This lid doesn’t have any hard to reach crevices where mold can grow without you getting to it. I love it this new one! The handle is wider so I can easily hold my water bottle with 3 fingers now instead of just 2. It didn’t leak at all! The quality is super good, and I’ve dropped it a couple times with no damage.

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