So... i finally tested my water with one of cheap testing kits. I know my water is hard/very hard - and it indicates 250 ppm, so probably in the right ballpark. The bottled water i use (forum recommendation - not this forum or country though!) looks closer to 500ppm!!!!!!! Might be time to change water and maybe descale the machine after 12 months! Have been trawling the forum and the internet and it seems a toss up between: 1) 5-Stage RO for £150 (£35 filters/membrane). 2) £110 for a Claris Ultra kit (2500L cartridge for £65) ... or BWT/3M equivalent. Questions and concerns i don't have a succinct answer for: - Is RO water good for coffee? I'm no super-taster, but i seem to recall reading the almost total absence of minerals is bad. But then i read the opposite... - How often does one change that £35 filter set in the RO? - BWT/Claris/3M cartridges. I recall reading that if they'r not used every couple of days they need to be flushed, or binned if not used for a few weeks. But never on any official documents. True? Any insight much appreciated
I have had the system over 2 weeks now and have completed my review. I do have a couple of areas I am still working on for some specifics re remineralisation and for sterilisation, but will publish those in a week or so. It's at least available for you guys to have a read and get a feel for the system. Some important things to keep in mind. I asked to review the system, they didn't ask me and there is no written agreement stating I have to do a review, or do a positive one. I could have just used it and said yeah it's great I'll mention it on the forum some time. They supplied a review unit at no cost to me. I don't get commission, use affiliate links and am not paid in any way by them BUT I recommend mentioning you're from the coffee forum, as I have tried to stress coffee people like us as a forgotten market for them. You might find them prepared to do a deal or throw some stuff in....just sayin. If you don't want to say you are from the forum fine...but at least try to get together with other members to benefit both of you for any deals going. If you are not on a water meter you won't make the stated savings, of course if you use bottled water in any reasonable quantity you will make significant savings If you have a similar workflow or setup to me, then you will most likely love the system, if you don't then just watch all the videos, read all the boring text carefully and see if it fits into your lifestyle. RO for me isn't a new thing, I've been banging on about it for 15 years now...but it was a surprisingly hard thing to review. https://coffeeequipmentreviews.wordpress.com/2019/01/06/osmio-zero/
