The Coway Airmega Halo brings whole-room purification to the mid-size category, cleaning spaces up to 1,898 sq. ft. in 60 minutes. A 360-degree pinhole air intake at the base draws polluted air in from every direction, while Coway's HyperVortex air technology - an aerodynamic fan and duct design inspired by eagle wings and golf ball dimples - maximises clean air delivery while minimising air resistance and noise. The 3-in-1 filter combines a vacuumable pre-filter, IEST-RP-CC007 certified HEPA media and a deodorisation carbon filter, reducing 99.97% of 0.3-micron particles including allergens, mould spores and wildfire smoke, and neutralising household and pet odours. A MegaScan sensor monitors PM2.5 in real time, and in Sleep Mode an intelligent Night Sensor detects darkness, dims the display and drops noise. ENERGY STAR 3.0 certified at 38 W.

Why Quiet Mark?

"I couldn't hear my baby crying over the noise of the hairdryer"

The damaging effect of excessive noise on health, productivity and social cohesion is seriously underestimated. World Health Organisation research shows that environmental noise pollution affects mental and physical health and is now second only to air pollution as the world’s largest killer pollutant. Across an estimated population of 340 million people, at least 1 million years of healthy living are lost each year due to noise pollution in Western Europe.

In our fast-paced lives, vibrancy is exciting and necessary. But this heightened state can only be valued if there is also the opportunity to choose the alternatives of calm, quiet and the chance to switch off. Quiet Mark was established to provide a credible, independent public health product symbol and directory to help consumers and industry easily identify quietest products for the home, at work and for public spaces.
