I can not open the filter to replace the cartridge.
The unit works extremely well and produces a good stream of well-filtered water. Unfortunately, the replacement cartridge can be impossible to replace. Yes, I've soaked the unit in hot water and vinegar. I've even used rubber straps to gain purchase and leverage. The company says I should just pack it up and send it back, and they will be happy to repair it for me. That's nice, but I would be much happier if the company had designed a better product in the first place.
