I have a Celltei but I have not tried the H20 bottle in it. I liked the idea that it was there.
You might contact Celltei & see if they have any suggestions. I have not seen one on their website, but that doesn't mean they don't have them. The people at Celltei are super nice and so willing to answer any questions.
I am not sure if you got it directly from them or not but this is the website addy.

Let us know what you find out.
