Testing of air purifiers has revealed the Coway Airmega 50 as the top budget option for smaller spaces. Designed for rooms up to 31 square metres, the unit is light enough to move between rooms and powerful enough for the average British home.
During testing, the real-time air quality indicator impressed with its coloured light system: blue for good, green for moderate, amber for bad and pink for very bad. This gives instant reassurance about indoor air quality.
The Coway Airmega 50 also features a built-in nightlight, making it a suitable choice for children's bedrooms. The gentle glow can help with bedtime routines or soothe children afraid of the dark.
Simone Miles, chief executive at Allergy UK, noted that for many people with indoor allergies, their home can be a hazard. “Having access to cleaner air can make a world of difference,” she said.
