Waterless ultrasonic piezoelectric diffuser · Model UD500
UHF Essential Oil Diffuser UD500
Floor area by ceiling height
3.75 m / 12.3 ft133 m² 1 435 ft² 500 m³ ÷ ceiling height
Scent is dosed by volume, so the fixed figure is 500 m³. Floor area is that volume divided by your ceiling height - double the height and the area halves. Open-plan rooms, atriums and stairwells count as one connected volume. Spaces with heavy fresh-air exchange or doors held open need de-rating; air-change data is confirmed per project, never estimated.
