There is only air coming through the mouthpiece on the cap. How can I fix this?
In this case, it is likely that the mouthpiece came loose. Luckily, it can be popped back into place. The mouthpiece needs to be reseated so it is aligned with the cap. To do so, raise the mouthpiece and firmly pull it straight up off the top of the bottle. Then, pop it back into place and try drinking from it. If the problem persists, it could be that either the straw detached from the cap or the filter detached from the straw. Double check to make sure all the parts are connected securely.
