Water Hardness Guidelines

Recommended maximum hardness: 250 ppm CaCO₃. If you live in a hard water area, you may need more frequent filter changes and descaling.

If your water hardness exceeds 200 ppm, consider a whole-house water softener to extend filter life and reduce scale buildup.

If your water comes from cold storage tanks, additional pre-filtration may be needed—contact us for advice!

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 lukewarm water
• Hot water (80 ° C - 88 ° C) ideal for coffee
• Hot Water 100C setting is a 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 90- 95C. A great tip for hotter dispensing is first to 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.

It's just so good! There is nothing else like this on the market. It solves the cost and time of installation and you can take it anywhere and have it in any room. It's really easy to fill up the water, you just take out the tank, fill it and pop it back in. The unit is completely stand-alone with no connection to the drain.

It makes the perfect choice anyone who wants the convenience of a top of range purification system with no installation and also for single people, students or small families, people who regularly travel and who are currently renting their property and cannot have a system installed on tap.

The unit is incredibly easy to use and assemble. Simply take it out the box, plug it in and fill the supply pitcher. Place it back into the system and turn the dial to adjust the temperature and press to dispense and stop, that's it! Within minutes you will have reverse osmosis quality water, ambient, warm, hot or boiling at your fingertips!

Filter change frequency

Filter life directly depends on the quality of incoming water. It is mostly affected by hardness, however other impurities can also cause premature blockage. You most likely will need a mid-term change of Carbon Block and Membrane filters if you have a hardness level of around 200 + Calcium Carbonate. 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!
