Extraction Rate of the IG9805igenix-ig9805-dehumidifier-review-byemould-mould-mold-damp-condensation-flood-commercial-domestic-plaster-drying

The Igenix IG9805 is stated to extract 50 litres of moisture per day however we have two concerns about this figure.

Firstly the test climate was a temperature of 30°C and a humidity level of 80%. I think that you’ll agree with me that we rarely receive this type of weather in the UK, especially during winter time when dehumidifiers are most commonly used.

Secondly the Igenix IG9805 is a compressor dehumidifier and this means that the unit becomes more efficient the higher the temperature rises. In low temperatures the extraction rate will be lower and the unit may not function if the temperature gets too low as it will spend most of its time in defrost mode.

Therefore due a combination of the above two factors your actual extraction rate will likely be significantly lower than the stated extraction rate.

Quick Tip: If the dehumidifier activates defrost mode when the temperature becomes too low for the unit to operate just put the heating on gently to help warm up the environment and make the dehumidifier more efficient.

Water Tank and Filter

The water tank is a massive 8 litres and is situated low down on the front of the unit. There is a clear plastic strip on the front of the tank which allows you to see the water level so that you can empty the tank before it becomes full.

If the tank does become full then the Igenix IG9805 will turn of automatically to avoid spillage and a light on the control panel will alert you that the tank needs to be emptied.

The dehumidifier will operate again once the tank has been emptied and inserted correctly.

Continuous Drainage

The Igenix IG9805 comes with a continuous drainage facility which allows you to use the dehumidifier in less visited places such as boats, caravans, sheds and garages.

You simply attach the 18mm hose to the rear of the dehumidifier and this allows the extracted moisture to by-pass the water tank.

The drainage system is gravity led so the dehumidifier will need to be placed above the sink or drain.

The control panel is nicely laid out and if you’ve used a dehumidifier before you will have no problems working this control panel.

For those who are new to buying a dehumidifier we will provide a brief summary of the control panel.

Power Button

The power button is located on the left-hand side of the control panel and obviously this turns the unit on and off.

Water Tank Full

Above the power button is the water tank full indicator which alights once the water tank is full (as described above).

Defrost Indicator

Above the water tank full button is the defrost indicator which comes on when the temperature falls below 12°C and the dehumidifier toggles into defrost mode.

Fan Speeds

On the right hand side of the power button is the fan speed button with two fan speed indicators above this button. You simply press the fan speed button to change between the two fan settings. The indication lights will show you in which fan speed the dehumidifier is operating.


Next to the fan speed button is the 24 hour timer button. When you first turn the dehumidifier on the dehumidifier will run continuously. Simply press the timer button to activate the timer. The timer settings will be visible on the LED display screen.

LED Display Panel

We love seeing LED display panels on dehmuidifiers as it saves buying a hygrometer to measure the actual humidity levels.

The Igenix IG9805 LED display panel shows the current temperature, the timer details, the current humidity level as well as the target humidity level.

To the right of the LED display panel are two ‘up’ and ‘down’ buttons which allow you to set the target humidity in 5% increments.

Operating Volume igenix-ig9805-dehumidifier-review-50l-extraction-8l-water-tank

Compressor dehumidifiers are generally louder than desiccant models and since the Igenix IG9805 is a very powerful unit you can expect a lot of noise.

Surprisingly Igenix have stated the maximum noise (ie in the high fan setting) which is 55db(A). Dehumidifiers typically list the low fan speed operating volume in their guides.

With a dehumidifier the size of the IG9805 you will probably mostly run the unit in its lower fan setting which means a lower noise and power level.


The Igenix IG9805 comes with a standard 1 year warranty according to the user manual. Amazon states that the unit comes with a 2 year warranty.

Final Thoughts

The Igenix IG9805 is a very large dehumidifier that is perfect for extracting heavy moisture very quickly. Situations such as drying plaster or drying a house, shop or office after a flood are perfect for the IG9805.

The unit is heavy but is fitted with caster wheels for easy transportation. We particularly like the LED display panel, the timer and the continuous drainage features.


The Igenix IG9805 currently rates at 4.7/5 on Amazon and here is what buyers are saying;

  • “It sucks out moisture really quickly – more than I was expecting”
  • “Great product, I use it to control the moisture in my garage”
