DavecUK Hope so, maybe everyone already got their own 😆😆, but it will be good if I can get another 2 ppl to buy together.

      matthew_luke As someone said, look back, one person has expressed an interest in addition to the original 3 that now have their systems.

      Contact me

        Is there anyone still interested? I need two more people to buy together. Thanks.

        This the the best thing I have bought way better than my Niche and Vostok had it for years now brilliant bit of kit never let me down

        Out of interest, does anyone know how much (in a v.hard water area) it costs per litre of filtration?

          Igm45 I use the hard water filters due to my Anglian Water region being relatively hard and roughly filtered about 4,400 litres on my first set. I average about 12l a day and had it just over a year before my change I’ve just done. So that would work out at roughly 1.4p/l.

              Alexvs Have you used normal filters before the hard water ones? If yes how long they lasted?

                  Inspector No I didn’t, I just felt it wasn’t worth it as they wouldn’t last as long and the cost benefit would be lower due to there only being £5 I think between them. Also when I ordered my refurbed unit direct from Osmio, I requested hard water filters to be fitted as my first set which they were happy to do.

                    Igm45 Out of interest, does anyone know how much (in a v.hard water area) it costs per litre of filtration?

                    The cost/litre would depend on wether or not you changed then at the Osmio recommended period of 6 months or used then until TDS readings indicated they were exhausted. The longer left in service the cheaper per litre the ave water cost is

                      If there is anyone would like to buy it, please let me know, I need 2 more people for getting this discount. Thanks.

                        Might be interested. Looked at this during an offer back at the old place and got as far as deciding to get one, but on asking Mark about my very hard water here, he didn’t seem that convinced that it was the right solution for me. I need to dig out the old emails and am a bit time-pressed right now. Not sure I can get in before offer time limit expires. So if anyone else wants slot 3, go for it. Meantime, I’ll see if I can dig out the mails (I don’t remember exactly why he seemed uncertain it was right for me).

                          CoffeePhilE What are the numbers for your water hardness? I’ve been using one for just over a year and have the following according to Anglian Water:

                          • 258.5 mg/l Calcium Carbonate
                          • 103.4 mg/l Calcium
                          • 17.992 °C Degrees Clark
                          • 25.85 °F Degrees French
                          • 14.683 °dH Degrees German
                          • 2.585 mmol/l Millimoles

                          It’s performed perfectly and we refill on average 3 times a day and only swapped filters after 12 months using the hard water filters.

                            122 mg/l Calcium

                            “Total” Hardness 305 mg/l
                            21.35 Degrees Clark
                            30.5 Degrees French
                            17.08 Degrees German
                            3.05 mmol/l Millimoles

                            0.15 mg/l Fluoride

                            According to water company, based on that “total” figure, this is “very hard” according to the “recognised classification scheme” they used. Figures above are current.

                            Either way, I quoted the figures at the time (similar to those but maybe not identical) and Mark didn’t seem … comfortable. IIRC, he felt some pre-processing would be preferable. Softening, IIRC. But I don’t remember exactly how he phrased it. It just felt like he thought it wasn’t necessarily a good idea, and would drive filter costs (if I remember right) up quite high.
