BUYERS BEWARE FALSE MARKETING - All four lights on the machine started flashing within 3 weeks of us starting to use the Osmio Zero Reverse Osmosis System. The company told us that it's because our water is hard (we live in Central London) so the water filters are clogged. This doesn't make sense because our water has to be toxic or full of rocks for it to clog the filters that are supposed to last 6 MONTHS that's 24 WEEKS.. within 3 WEEKS, that's 21 WEEKS or -87.5% shorter than advertised! The company representative said the 6 months estimate in some cases could be shorter based on your water hardness level... BUT HELLO, 3 WEEKS vs. 6 MONTHS (87.5% DIFFERENCE)?!?!?!? That's absolutely fraud marketing. Also, it's been very disappointing because the company's standard response is to blame the water instead of trying to find solutions to help their customers.
