In stock

The installed version of the Osmio Zero is here! Ideal for larger families (5+). If you have less than 5 occupants we would recommend you check out the Osmio Zero. Osmio's latest compact, countertop reverse osmosis water filter, the world's first revolutionary, installed household Reverse Osmosis (RO) counter top water purifier which also serves to provide, ambient, hot and nearly boiling hot water at your fingertips with great ease of use and easy maintenance. A filter kettle like no other installed reverse osmosis system!

Osmio Fusion Reverse Osmosis System - Smart and highly efficient reverse osmosis water filter and kettle that will produce high-quality water with countertop installation and super easy user maintenance.

Available in White

The Installed version of the Osmio Zero is here. This system is ideal for larger families (5+) and offices where an Osmio zero would not cope. If you have less than 5 occupants we would recommend the Osmio Zero instead! The Osmio Zero is completely portable meaning it does not require a plumber. The fact that the Zero is not connected to the drain means you will only have 1 litre of wastewater which is contained and does not have to go down the drain. Use the Osmio Zero wastewater to water plants or to clean with.

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 - 95° 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 a thermometer at the very top where the water comes out, you will measure around 93-95°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.

Please see section 7 in the manual for warranty terms.

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 installed on the counter needs to be plugged into a power supply. Tubing to the system feeds from the cold water pipe and access to the drain is also required. A water source that 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 been completed. The intelligent, automatic, power-saving motor design, gives an instant supply of filtered water, and automatically shuts off when filtration is complete.

An ideal investment for larger households!

The system has an automatic shutdown mode, after 1h the device switches off automatically, so you save power!

Filter Stages

1 - Quick-Change activated carbon filter: removes chlorine and organic impurities
2 - Quick-Change Membrane 50GPD: removes all pollutants and flavours to almost 100%
3 - Quick-Change Insertion Filters: Hygiene After-filter antibacterial calcium and magnesium bioceramics, adding a small 10-20 ppm of minerals.

Recycling the plastic parts of the Osmio Fusion filters is possible. Osmio Fusion Carbon Block - The carbon block inside this filter is NOT RECYLABLE. It must be taken out by first sawing off the very end of the filter. It can then be pulled out or you can use pliers to help. Please do not attempt this if you have any problems using a saw. The carbon can be composted or broken up and scattered onto soil. Crush it up and mix it into compost or soil - it also works very well in pot plants. It will increase soil aeration and water retention. Or you could put it in the bin where it might do some good in the landfill.
Osmio Fusion RO Membrane - put straight in plastic recycling
Osmio Fusion Post FIlter - this too has to be sawn off to remove the balls inside which are not recyclable but can be processed the same way as the carbon filter and the remaining plastics into recycling.
The plastic components of those filters can be put into the plastic recycling bin. You would need to take care if you are cutting open the filters, otherwise, you can just be put in the general waste. Osmio and other sanitaryware companies cannot make new products from recycled plastics, but there is a large range of products that get made from them, so long as the council is doing proper recycling.

Does this come with the first set of filters?
Question by: lee on 18 Jul 2021, 23:27
Yes, unit comes with pre-installed filters
Answer by: Irina Orlenko on 19 Jul 2021, 13:30
Hi, I live in a hard water area with 116.8 cal mg/l. Could you give me an idea of how often I would need to change the filters for the Osmio Zero please, as I like the simplicity of it. Or would I be better opting for the Osmio Fusion? Many thanks
Question by: Samantha on 27 May 2023, 21:37
116.8 mg/l as calcium = 292 mg/l as calcium carbonate and the maximum recommended hardness for the Osmio Zero is 250 ppm so an Osmio Zero would not be recommended unless you have a softener installed and are going to be filling the system with softened water. If you want to use the Osmio Zero and need a recommendation for a salt softener for your property please contact us.

Hi I changed the filters on my Fusion Installed Reverse Osmosis System but the orange maintenance light stays on and the beeping continues. How can this be reset? I tried powering off overnight and emptied the tank several times now. Thanks
Question by: David on 26 Jun 2023, 07:55
Please see the manual section"Resetting System After Filter Change", under the Files tab on this page

How many litres of water can I draw from the fushion at one time and then how long until I can draw that quantity again?
Many thanks
Question by: Dan on 3 Jul 2023, 20:57
It has a 1.2 litre internal stored water tank, which would take 5-12 minutes to refill or longer if the filters are more blocked
Answer by: Mark Kent (Admin) on 4 Jul 2023, 10:16
Does this come with a remineralising filter as standard and is it compatible with the alkaline filter? I’m so confused!
Question by: Sara on 21 Oct 2022, 22:03
The Fusion does come with a remineralising filter as standard. It has three internal filter and one external pre filter. If you can contact us and let us know what alkaline filter you are referring to we will be able to further advise. email info@osmiowater.co.uk
