What is the Home One and how does it work?
The HO3 Home One is a water treatment system that removes impurities from water through reverse osmosis. It does not require a fixed water connection and can be used flexibly.
How is the device filled with water?
The device has a 5L raw water tank. The tank can be easily removed for filling. The raw water tank has a separate compartment for dirty water.
What is the clean water to wastewater ratio?
The pure-to-drain water ratio for the Home One is 2.3:1. This means that 5 liters of raw water yield 3.5 liters of filtered water and 1.5 liters of wastewater.
How long does it take to filter water?
The appliance has a 1.5-liter internal tank where filtered water is stored. As soon as water is dispensed, the appliance automatically begins the filtering process, so that 1.5 liters are always available.
How often do the filters need to be changed?
This depends on the respective filter, actual usage, and the quality of the tap water. Reference values for 5 liters per day are:
CF and MN filters: 12 months
RO filters: 16 months
Can I use the Home One in my motorhome or on a boat?
Yes, the system is ideal for use in RVs, boats, or other locations without a fixed water connection.
What maintenance is required?
In addition to regular filter changes, occasional cleaning of the device is recommended to ensure optimal performance.
The water doesn't get to 95°C. What can I do?
A kettle reaches an effective temperature of 93°C. The flow heater of the Home One reaches the same temperature. On the way from the flow heater to the glass, the water effectively cools down to ~87°C. A difference is not noticeable.
The machine dispenses less water than I specified. What can I do?
This can be very easily calibrated on the display. Connect the device to the power supply, press and hold the volume button for 5 seconds during startup, and choose between -20% and +20% output volume. The device is calibrated.
Is there a money-back guarantee and what is the return policy?
HO3 offers a 30-day money-back guarantee. This means you can test your Home One for a month without obligation. If you find within this period that the Home One is not right for you, you will receive a full refund of the purchase price upon return of the product. Simply send an email to the Customer Happiness Team - no questions asked.
