Water Temperatures


The system can provide the following osmotic level water with organic calcium and magnesium active ceramic:


Normal temperature water (approx. 25 ° C), ideal for direct drinking
Warm water (40 ° C - 50 ° C) ideal for baby food
Hot water (80 ° C - 88 ° C) ideal for coffee
Nearly boiling water (90 ° C - 98 ° C) ideal for tea - PLEASE NOTE - the system reaches 100% but then travels through the route to the dispenser and loses some degrees. By using at thermometer at the very top where the water comes out, you will measure around 92- 95°C. A great tip for hotter dispensing is to first select 100°C Setting, and let the water get hot and make your mug hot. Then press stop and empty that out, then go again with a new 100°C press and the results are much better.

How to recycle and dispose of Osmio Zero water filters 

Quick-Change activated carbon filter and Quick-Change membrane 50GPD filter: these two filters can be placed in plastics recycling. However, the bottom of the filters will first need to be cut open using a hacksaw. The carbon and membrane elements can then be removed and thrown into the bin before placing the filters in recycling. 

Quick-Change Sediment filter: This can simply be placed into the plastics recycling. 

Quick-Change Insertion filter: This filter should again be cut in half and the contents emptied out into the bin before recycling the plastic exterior.

No Installation RO System


3 year free repair warranty for customers in the UK (free returns)*. 

Customers within the Northern Ireland, Republic of Ireland as well as the following EU coutries: Austria, Belgium, Czech republic, Denmark, France, Germany, Netherlands, Luxemburg, Slovakia, Slovenia, Spain, Italy, and Hungary can also take advantage of this service but they are required to ship the system to us (no free returns). 

We also offer repairs after 3 years for a small cost.

*Please see section 7 in the manual for warranty terms.

There is optional 5 year extended warranty available. 

Please note: There is potential for the Osmio Zero to drip and for there to be a small amount of water underneath the system. This can be worse if the supply tank is allowed to get very dirty and with limescale buildup. So if you have a wooden, untreated worktop, it is recommended to put the system on a tray to avoid damaging the worktop. If you have a laminate or granite worktop this would of course not be a significant problem. It is recommended to clean the supply tank periodically and descale it, plus use a cloth to soak up and water that comes out from the tank connection at the base during supply tank refills. 

Filter change frequency

If you have a hardness level over 250 Calcium Carbonate then you may need to change the carbon block and membrane more frequently than every 6 months. The unit is designed to shut off if there is a 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 carbon block and membrane changes are likely. It is recommended to have at least a spare carbon filter and membrane on hand with the unit at all times. 

The first thing to note is that the system is amazingly easy to use and maintain and as Osmio, we have spent great investment into the product and our culture is customer care. We are passionate about our products.

The system is designed with ease and practicality in mind. The unit has a very simple user interface. Water comes with the turn of a dial and there is no complicated user manual needed. The system is fully portable and just needs to be plugged into a power supply. It does not need to be installed into household plumbing. Any water source gives you easy access to fresh and healthy RO pure water at any time. 

Changing the filters is really quick and easy. They come off and go back on with a simple twist function.

The colour coded LED instantly shows when the filtration has completed. The intelligent, automatic, power-saving motor design, gives instant supply of filtered water, and automatically shuts off when filtration is complete.

An ideal investment for small households! There is just the need to plug it into a normal power supply. Only a power connection via a simple plug socket - done!
The system has an automatic shutdown mode, after 1h the device switches off automatically, so you save power!

Featured Review

Review by Dave Corbey - Coffee Equipment Reviews - "I’ve been using the system for over 2 weeks now and I have to say I really like it, a lot. It’s saved me time and space both above and below the counter. It makes life so much easier and everyone ion the family loves it. On the cost front, sure there is a larger outlay initially, but doing the math it actually works out cost neutral (family of 4). Based on being on a water meter and the fact that under counter systems need end of life replacement and filters over time. I truly believe it doesn’t actually cost more to be greener and you get a heap of convenience thrown in. If you are not on a water meter then sure it’s going to cost more than an under counter system but if you can afford it…why not save all that clean water from going down the drain. For bottled water users, it’s going to save a lot of money and definitely help the environment in terms of plastic waste and the carbon used to produce and transport the water to the supermarket, only for you to transport it again. If you can afford an expensive coffee machine, then you really need to use great water and the little Osmio Zero gives great water!"

Product Questions

Sort by "ASC"/
Does this product remove all of the fluoride from the water?
Does it remineralise the water and is the water acidic?
Hi do you have collection points for the used filters to be collected for recycling?

I can't any details information about membrane hole size (is it around 1 nm?).
I'm particularly interested in information if your's filter can filter out the Glyphosate?

How do I suspend the use of my machine? I am going away for 3 months and have only had use of my machine for 3 months.
Is it appropriate to press the button (i.e., fill cup with water) while the light for 'filtering' is on? Will it impact the filtration process? If there is not enough water in the reservoir, will it simply just not eject water when the button is pressed?
Is it easy to clean and how often should you do this?
Which filters do I have to order as spare for the ZIP-II?
Hi, how often (roughly) do you need to change the filter? Thanks
Is there a document showing what actually has been filtering out?
Hi can I use this without remineralising the water, I want this for making water for my nano marine tank and need water at 0tds my water changes are ( 7 litres) so want something as little fuss as possible, I have a Rodi unit but am moving soon and am looking for something as little hassle as possible? K
Hi does this product (Osmio Zero IP-II Portable Reverse ) filter lead? If yes what percentage of lead is filtered out and is it NSF international certified?


What's the average yearly running costs for filters?
The drinking water - it comes out at 25 degrees? What are the effects to the water if I chill it in a fridge after dispensing from the machine?
The tea water - does it come out at 100 degrees? I like my tea very hot so if it's not boiling the machine would be of no use to me.


Bought this machine recently and all working fine. Simple to set up. Bought it as we have a water softener using salt to soften the water for the house. Just wanted to confirm again that this system will filter the softened water back to drinking water.?
Hi. Does this filter out Magnesium Sulphate and Sodium Sulphate? Thank you
Hi! What’s the PH after using the Osmio Zero filtration? Approximately...
(1) Does the removal of minerals rely in any way upon sodium ion exchange - i.e. replacing mineral ions with sodium ions?

(2) Would I in any way find the water had a higher sodium content following filtrations?

(3) I am assuming that the remineralisation (to add trace quantities of Mg and Ca) is to mimick those (healthy) levels I'd expect to find in hard water (e.g. in Hampshire). Correct? How were the ppm quantities decided on?
Does your product remineralise the water so that the pH is not too acidic?
Hi, does the osmio zero remove limescale?
Hi, You say the system doesn't remineralise the water but what about the last stage filter with magnesium and calcium? What does this do?

How energy efficient is this?

Is this bpa free?
Hi, I have an ezfitpro 200 filter system and was looking for a counter top water boiler for drink preparation. I noticed your RO water system and wondered if I am be able to use the filtered water from the ezfitpro in the Osmio Zero Installation Reverse Osmosis System to further improve water quality?
Also how does power consumption compare to a kettle, on say, boiling 500ml of water.
Many thanks.
Hi, can you use different qualities of water or river, pond etc like the gravity filters or just tap water, and can it only be used with electricity or can the cold water option be used without electricity? Many thanks
