If you have a dishwasher, Neti makes stainless steel insulated bottles that are dishwasher-safe. (I’ve had mine for many years and they hold up very well even with frequent dishwasher visits!)

I also have a Larq and love it, but it is a whole different lifestyle. It has a UV light in the cap that kills everything living in it so you only need to clean it once a month. (I do rigorously rinse it out more than that.). It is, let’s say, an investment piece of a water bottle but it has been worth it to me because I have used it a TON.
