Water Temperatures

The system can provide the following water:

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

The first thing to note is that the system is amazingly easy to use and maintain and Osmio have put a great deal of investment into development resulting in an excellent product.

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.

Filter Changes

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!

Recommended filter change period is every 6 months, maybe a little more or less depending on useage and water hardness.

Replacement filter pack available here.

If you live in a hard water area then you may need to change the carbon block and membrane more frequently than every 6 months and do more frequent descaling (maximum hardness recommended is 250 ppm CaCO3). 

It is not recommended to use the Osmio Zero if your water is over 250mg/l total hardness and if it is supplied via cold water storage tanks )which accumulate more scale and other solids adding to the problem). If you have these problems but still want to use a Zero, it is possible if you consider a good point of entry filter and softener system. Contact us if you want help with that.


Filter Stages

1 – Quick-Change Sediment Filter 5μm: removes coarse particles, e.g. Sand, rust, chlorine, lime
2 – Quick-Change activated carbon filter: removes chlorine and organic impurities
3 – Quick-Change Membrane 50GPD: removes all pollutants and flavours to almost 100%
4 – Quick-Change Insertion Filters: Hygiene After-filter antibacterial: removes 99% of the bacteria and viruses and improves the taste.

What about the loss of healthy minerals? With the Osmio Zero – no worries:

    Arrived quickly. Not a cheap purchase but good quality. Great piece of kit, useful & looks good. No problems so far.

  2. Jayne Longhurst

    Very quick service from ordering the Osmio to delivery was one day. This Osmio does exactly what it says it does. The purified water is so smooth, light and has a great taste. I especially like that l can make a hot drink. Very easy to use and keep clean. Thank you.

    A revolutionary product to make sure your health is on good hands. The Osmio machine is perfect and super easy to use. It is an investment, but what is more important than drinking cleaned water. I used a tester to check all the Heavy Metals and other chemicals added to the tap water and I was discusted by the result. So this product brings the water to a pure drinkable water. It is an amazing product and I will keep spreading the word as drinking pure clean water is perfect for the brain and other important body functions but also the investment is worth thinking for the other appliances in your kitchen e.g. cofee machine, Iron machine… no need to think of having to descale in the future.

    Much better than I expected, I was only looking for a RO filter, the option for instant hot water is fantastic, we got rid of our kettle on day 2 of getting this system.

    Excellent product

  11. Leonardo (verified owner)

    Overall the product is excellent in our opinion. It totally replaced the kettle, you get instant hot water at the touch of a button. We also have toddler and the fact we can dispense hot water at the right temperature for the formula again at the touch of a button, its a time saver to say the least. What I will say is that as 2 adults and 2 children, we are having to fill it up on a daily basis. But i am just nitpicking here.
