“Bought two units for the living room (daytime use) and bedroom (nighttime use). High floor flat, it gets surprisingly dusty and there's a persistent mould issue on some wooden items. These purifiers reassures the air in my house is clean and fresh. Finding lesser mould too. Also gets rid of odours, even detects pungent perfumes. Improvement with my sinuses in the mornings as well since using it overnight. Recommended buy.”
