You can buy a pack of replacements from Amazon. If you are pretty much always drinking from an owala and not using any other water bottles, I would recommend washing it every 3-4 days. Daily, definitely should rinse it out with tap water and rinse the lid/spout areas too. At least once a week you should fully disassemble the water bottle (including removing the silicone bit) and hand wash it with warm water and soap. You can purchase specialized brushes to get into all the nooks and crannies, or even just use a toothbrush (but I would definitely invest in a straw cleaner if you don’t have one). The biggest thing is letting the pieces dry completely before using it again, otherwise they are just constantly exposed to moisture and risk getting moldy. Here are some products I recommend using to clean or use for your owala.

Just a thought, may not be something you are interested in.
