Key Features


Designed to heat, cool and purify a whole room quickly and evenly, the unit has powerful air projection, while also capturing pollutants and fine particles.

Silent Operation

The night-time mode is designed to purify the air in your bedroom, using the quietest settings and a dimmed display to not wake you up.

Smart Technology

The app allows users to set the temperature or monitor the air quality either from home or remotely.

45 to 350 Degree Coverage

Air Multiplier technology and an oscillation angle project purified air, heating or cooling every corner of the room between 45 to 350 degrees to best suit requirements.

Safety Features

Safe technology ensures that as the heating elements heat up, their ability to conduct electricity decreases to help prevent overheating. If the machine does over heat or falls over, it is designed to auto-switch off.

Intelligent Thermostat

Uses an inbuilt intelligent thermostat for improved efficiency, automatically stopping heating or cooling once the target temperature is reached, saving energy.

Expensive but performs

Very quiet compared to others. Electronic assistance and app are good. Have a very large space and it copes excellently. Air quality a plus.

Very Good Product

Bought this as my wife and kid couldn’t sleep at night due to hay fever blocked nose. Except for 2 nights in 4 weeks, they’ve slept well.
