'Connect to almost anything, using the universal connectivity system. The Frontier Pro filter will connect directly to any water bottle with a 28mm opening such as a Platypus® or standard spring water bottle'
These things are good examples of overspecialization and everyone trying to put something unique (read 'gimmick' again) in their product, rather than just building a water filter. I would not buy, or even consider a device that is so specialized as to use a threaded connector to the receptacle.
Get a real pump, and do the minimal effort required to force water through it into whatever container you might want to use.
