More Details

Stay cool without the hassle of installation

The BLU09 is one of the most reliable portable air conditioners available in the UK. Built to a high standard with quality components throughout, it delivers consistent, quiet cooling without the rattles and vibrations you get from cheaper alternatives.

It works straight out of the box. The included window sheet fits UK inward and outward opening windows, the expandable exhaust hose connects in minutes, and the remote control lets you set your preferred temperature from across the room. That is all there is to it.

3-in-1 comfort all year round

While summer cooling is the headline, the BLU09 earns its keep beyond July and August. Switch to dehumidifier mode to tackle condensation and damp in autumn and winter, or run it as a standalone fan during milder periods. One unit, three uses.

Clean cooling for allergy and asthma sufferers

Portable air conditioning is often overlooked in air quality conversations, but keeping indoor temperatures stable plays a real role in managing hay fever and asthma symptoms. Overheating increases airborne allergen activity, and open windows, the usual alternative let pollen straight in. The BLU09 lets you cool the room without opening up to the outside world.

Eco-friendly by design

The BLU09 uses R290 refrigerant, one of the most environmentally responsible gases available. It carries an A energy efficiency rating and meets EN14511 standards, so running costs stay reasonable even during a prolonged heatwave.

The practical details

At 26.5kg it is not lightweight, but the four castor wheels make moving it between rooms straightforward. The self-evaporating system means you will rarely need to drain a water tank useful when the unit is running through the night with the sleep function active.
