Chill Oasis Replacement Lid Compatible With Cirkul Water Bottle | Fits Flavor Cartridges | BPA Free, Leak Proof, and Dishwasher Safe

I was tired of the original lid not getting any air for a solid 75% of the time. I was constantly having to slightly unscrew it after every swallow to release the suction. I put this replacement lid on, and haven't had a single issue. I have the 20oz plstic bottle, and a metal bottle, as well. It fits both.

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.

Overall, this lid works well. It is sturdy, fits my non-Cirkul brand water bottle, and looks good. The only issue I have is that it does leak a little bit sometimes. Also, just to note, there is a little rubbery plastic piece that needs to be pulled off under the lid if the water bottle doesn’t have a hole for pressure equalization.

It fits my 32oz insulated baba perfectly and the flavor cartridges. Taking it on my next mission trip to El Salvador. So excited to have something that keeps my water cold all day and night even in central america, that I can use my flavor cartridges on.

After multiple months of use with my 42oz stainless steel cirkul bottle, I will say it is easier to clean than the standard ones, which is the primary reason I tried it. Standard water filters for cirkul bottles/cartridges are not compatible attachment The angle on the handle is more… sharp/aggressive? and not comfortable to carry, if you grab it from this lid the same way repeatedly. I ended up developing very thick calluses that one ended up splitting this winter and hurt a lot so try to switch hands/fingers when carrying by the lid.
