Reverse Osmosis - Osmio Zero review


Recommended Posts

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.

 

  1. 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.
  2. 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.
  3. 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.

@Chilledmatt I'm also in Norfolk, and now have an Osmio Zero, so you can base the impacts etc on my figures if you wish. I used to use a Britta jug with genuine cartridges, and also tried a under

Thanks Dave

 

This review has helped me so much and before this I was very close to having an under counter system but your thoughts has convinced me otherwise.

He bought it, I think he mentioned it before in a reply on a thread.

 

No I didn't buy it, I was going to but he said he would send one and it arrived the next day. Thought that was clear in the review, so perhaps I need to check and possibly clarify.

 

Just checked, perhaps saying I asked to review it wasn't enough and I need to make it clearer when I get back home.

@DavecUK

Dave, thank you very much for this.

 

The first mention of the Osmio Zero, a couple of weeks ago, piqued my interest but I had questions that wanted answering. This review has provided those answers and more.

Over the past four or five years, our tap water, courtesy of Severn Trent, has been disappointing to say the least. Often times we get discoloration and visible sediment. The smell of chlorine and goodness knows what else, varies but is often unpleasantly strong. Other than coffee, we mainly drink water, often ambient but mainly hot. Our heated tap water tastes like TCP so, for 5 or 6 years we have exclusively used bottled water which at times is most certainly a PITA to fetch and carry.

Of late we have felt increasingly guilty every time we scrunch up an empty water bottle and put it in the ‘recycle’ bin.

 

So, we have just ordered an Osmio Zero and feel better already!

And yes we did talk to Osmio before we ordered. ;)

Thank you once again.

Did they give you a deal, I suggested they should think up something for the forum members?

 

Oh and from the sound of it, I think you will absolutely love the unit. Just remember I felt it was about 10-12 litres before all the new taste disappeared from it.

Yes. The offer of a free Osmio Hydrogen Water Bottle or a set of filters. We went for the filters.

Definitely the best move. I should have mentioned it in the review but I was told when the maintenance light flashes you need to change filters and that there is no warning. you can reset it by switching power off at mains and on again, but it soon comes on again. The solution to have a set of filters in hand. I must actually order myself a couple of sets soon....I also realised we're quite heavy RO users. Already today the unit has been filled 3 times! That's 12 litres of RO already and I suspect we will fill it twice more before the evenings out. no wonder my water bills were so are high with the under counter unit and perhaps I will need a filter change sooner than I think.

 

The one surprise was how fast it is to filter, but then it can wash/flush the membrane loads , because it's simply recycling the water back, ah well you'll experience it for yourself tomorrow.

Yes, we have already determined that it will be good policy to have a set of filters to hand and to re-order as they are fitted.

I would be surprised if we exceed 4 litres per day so I reckon it will be spot on for our needs.

 

Does anybody want to buy a kettle?

Thanks for the detailed review. Some minor points:

 

You mention "Fortunately this can be easily fixed by adding 0.15 of sodium bicarbonate to every litre of water. When shopping for it in the supermarket don’t buy baking soda, it’s not the same thing." . Baking soda IS Sodium Bicarbonate, maybe you meant baking powder?

 

Further down it says "so an alternate water treatment plan for coffee machines could be 0.8g of Bicarb per litre and leave the remineralisation cartridge in. I’m still testing this area and will update soon.", I don't think you mean 0.8g/L but maybe 0.08g/L? 0.8g/L would be 500ppm akalinity. 80mg/L should be enough and is within the SCA guidelines (~50ppm)

 

Did you also get to measure the output TDS without any re-mineralization?

Will go through and amend errors, but yes you are correct.

 

I have not yet I will be removing the last filter tomorrow and checking, but it should be close to 0

It is also worth to remember about this:

"We offer a 1 year warranty for customers in medium hard up to 200 ppm Calcium Carbonate Hardness and TDS of 250 ppm. For customers with harder or water with higher TDS, we do not recommend this product unless you are happy to make be more frequent membrane filter changes. The unit is designed to shut off if there is blockage in the membrane or prefilters. As the system recirculates the rejected water from the membrane, the TDS level continually rises of the water entering the membrane filter. Therefore, for those with water of higher TDS, more frequent membrane changes are required. "

So if you leave in London, you probably have to look for other options.

 

 

Nope, I don't think so, I think they are being over cautious and if you use RO of any kind they are all equally affected for water hardness. I think they were trying to be super careful to set expectations, but it's probably not setting the right impression. e.g. if an undercounter RO systemhas a cost that cost goes up the harder the water is, both in reject water and membrane life, with this system it's the same so nothing really changes relative to undercounter systems. Their big mistake was in scaring people off, rather than people just understanding it's more frequent changes. I think the warnings used to be along the lines of not recommending it.

 

It doesn't change the warranty, your still covered. In fact my water can be up to 300 ppm in summer sometimes and is around 250+ now. If I have to change my filters every 5 months I don't care. The other way around it is simply to change the water out with say 1.3 litres left instead of 1 litre.....then the membrane will last the 6 months...but i'd rather not muck about. The corollary is that if your water is softer than 200 ppm then your filters will last longer than 6 months......

 

The bottom line, if you live in London, then you definitely need to use RO, just change the filter a bit more often and they do have a twin membrane filter only option for those super dooper hard areas (e.g, east anglia etc..).... 2 membranes for £45, so you can always swap out just the membrane for £22.50, as it's only the membrane that's affected. The other filters don't much care about hardness....they time expire and go on chlorine etc..

OK, so maybe in that case they should be more clear on the webpage, as for me, non-native speaker it looked like, for hard water they recommend the classic RO system that does not circulate water.

And yes I agree, in area with such hardness as London or Warsaw, where I live, something like this is a must.

I have discussed this with them, so I understood their concerns, but I think they understood that perhaps they give the wrong impression. They didn't want people to have a unit, have to change the membrane more often than 6 months and complain or think the company had been dishonest. Really though the people in areas like yours need this type of system the most.

Thanks for the review Dave. I've been looking for a solution for a while and I've thought about gravity filters like the Berkey and RO systems. The Osmio sounds like it could be the perfect solution. I personally drink around 3 litres of bottled water a day and I really want to find a clean alternative. What I can't work out from the Osmio is how long would it take to fill up 1 or 2 1.5 litre bottles?

How about the taste, compared with bottled or jug filtered water, for light roast beans? I take not many home users have RO systems installed, so that might be their first experience with it.

 

I am not really interested since water in Glasgow is soft and does not produce any scale - just has a chlorine smell which I started to hate after starting to filter the water! BWT jug does the job for me.
