  • Easy to sterilise and clean with blank filter kit.

Osmio Zero Reverse Osmosis System – Smart and efficient reverse osmosis filter and kettle producing high-quality water with zero installation and easy maintenance. Highly recommended for households or workplaces with 4 people or less.

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 dispenser and so reduced to around 92°C- 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.

Simply un-box, plug in and fill the water tank from your tap. Place it back into the system and turn the dial to adjust the temperature and press to dispense, that’s it! Within minutes you will have reverse osmosis quality water, ambient, warm, hot or boiling at your fingertips!

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.

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.

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

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 calcium and magnesium bioceramics, adding a small 10-20 ppm of minerals.
