Hello Mark, That is a great offer. Thanks. I am interested. Price of Volvic is going up and up. Is anyone else interested in this, to do a group buy?

TBH this is the first I have heard of the Zero… so currently reading the 40 page thread at the other place. Being in hard water Kent - it could be a useful solution to go with the water softener!

@"MattH"#p37622 I recommended osmio to a friend of mine who lives in Swanscombe their tap water is pretty hard, filters last him 5-6months, I think he can get another month or two with resetting the unit but I told him to try hard water filters next time, they are £5 or so more expensive but might last longer. They are really happy with osmio. We live in a medium hard water area and our filters last more than a year. We are also really happy with it, been 2.5 years. Only time we needed kettle was to fill a hot water bottle:)

@"Inspector"#p37637 Top tip If he **empties** and refills the Osmio when there is about 1.5 to 2 litres left instead of letting it completely run down before **emptying** and then refilling…his filters will last much much longer! I have suggested to mark they have 2 small extension tube options made for the particulate filter in the tank for very hard water areas…say a 1.5 and a 2 litre

Ok I am in for one if this goes ahead…. White or black now is the decision to make :) I think sorting my water is more important than which Machine to buy at the moment.

Please note, that if you live in a hard water area its important to descale these approx every 3 months. The white finish is more durable than the black if that helps

If it helps, I'm in a hard water area and mine has been running nearly 12 months with the hard water filter and doing great. We use it for daily drinking water, filling the Minima and occasional hot drinks, filling the tank probably twice a day at a minimum. For the price it's a great deal with sanitisation kit too (which I should probably get on its own). @"OsmioWater"#43 - Mark, any chance of a deal on some filters as mine will probably need doing in the next month or two 😁

@"Alexvs"#p37695 If the group buy happens - I would be up for getting a set of filters etc 😂

If you guys want to do this successfully you need to have disposable e-mail signatures set up in your signatures, so you can start communicating with each other and making a list (of whose in) in this thread. **How to set up these disposable threads using a free, and very good service is here** https://coffeetime.freeflarum.com/d/229-private-messaging-important

@"DavecUK"#p37705 Sorted - thanks !

matthew_luke Some one had shown an interest after the first group buy. Please scroll up and check.

Btw, welcome to the forum. Thx

matthew_luke

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

DavecUK

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

matthew_luke

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

Jony

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

Igm45

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

Alexvs

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.

Nightrider_1uk

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

Inspector

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

Alexvs

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.

matthew_luke

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

Uncletits

matthew_luke you could always ask them for a graded price A,B or C - I did and have been very pleased with my product

TheDamnedCoda

@matthew_luke hello i’m intrested in forming a 3

matthew_luke

TheDamnedCoda Great! One more to go!

matthew_luke

TheDamnedCoda would you please give me your email address or send an email to me ( cakepk@gmail.com) , so that I can send it over to Mark once we good to go? Thanks.

matthew_luke

TheDamnedCoda Hi, may I have your email or please send an email to me cakepk@gmail.com, if we can’t get 3 ppl by this week, I will still ask Mark to see if there is any discount for the machine. Thanks

CoffeePhilE

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).

Alexvs

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.

CoffeePhilE

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.

TheDamnedCoda

matthew_luke hi I’ve sent you an email 👍🏻
