    Overview

    The Ionmax Rhine Pro ION651 is a high-capacity, dual-function appliance designed to tackle severe humidity challenges while enhancing indoor air quality. With the ability to remove up to 50 litres of moisture per day, it's ideal for larger homes or spaces up to 300 cubic metres that suffer from persistent condensation, dampness, or mould.

    At the core of its air purification function is a medical-grade H13 HEPA filter, which captures 99.95 percent of airborne pollutants including allergens, dust, and fine particles. This makes the Rhine Pro particularly suitable for allergy-prone households or environments requiring cleaner, drier air.

    The unit offers a generous 5-litre water tank with automatic shut-off and a full-tank indicator. For long-term use without manual emptying, a 1-metre drainage hose is included for continuous water removal. Castor wheels ensure easy mobility from room to room, while the built-in child lock and auto-defrost features add safety and durability in variable climates.

    Smart control is available via the Ionmax app, which enables remote monitoring and adjustment of humidity levels, fan speed, and timer settings directly from your smartphone. The intuitive onboard panel provides quick access to the same controls, including a 24-hour timer and custom humidity settings.

    Operating efficiently between 5 and 35 degrees Celsius, the Rhine Pro also doubles as a practical clothes-drying aid, offering a powerful and energy-conscious alternative to traditional methods. Whether you're drying laundry indoors or controlling high humidity in warm, tropical environments, this robust solution ensures a healthier, more comfortable living space.

    It works (too well)
    Our last dehumidifier had a pump to get rid of the water, this one doesn't, but everything else about it is better. It's quieter, it has a HEPA filter which means its evaporator coils don't get covered in crap that comes out of the air as water condenses, it's got wifi to remind you that its tank is full again, its dark grey is nice; more subtle than white. The tank does need to be emptied a lot! I'm looking into a submersible or condensate pump. I have not (yet?) succeeded in getting it working in home assistant.

    Pretty happy
    Based in SEQLD, purchased to keep humidity down in rooms with equipment that needs humidity within certain limits. It is great at reducing the humidity and I was surprised at how often I had to empty ( some days up to 3 times) I don’t like that the humidifier is putting out warm air so makes the room quite warm and still have to put air con on.
