The Details

Aristons range of DEOS dehumidifiers are excellent at lowering humidity levels in a property, reducing the build-up of condensation, mould and mildew. They also help to eliminate signs of damp, as well as prevent condensation from forming on windows. Plus, having three different capacity models means there is always an option available for any sized room

The DEOS 21 is capable of absorbing 21 litres per day, which makes it perfect for small bathrooms and utility rooms. It features a sleek, modern design, alongside a safety indicator light and tank full block, the latter providing a warning when the maximum water level is reached, allowing units to be emptied safely once full. There is also a two-year warranty for added peace of mind.

In addition to the features of the Deos11L & Deos16L, the Deos 21 also includes Super laundry Function, Air Purifier and Anti-Mildew

SUPER LAUNDRY FUNCTION - Specifically designed for drying clothes, automatically setting the fan speed depending on the humidity and temperature in the room

ANTI-MILDEW - By automatically setting the Relative Humidity, this function maintains maximum comfort and a healthy environment by reducing the growth of mildew and bacteria

AIR PURIFIER - This function utilises the built-in HEPA (High Efficiency Particulate Air) filter to eliminate dust, bacteria and allergens, reliving you of allergies such as asthma
