The development of the fragrance is dependent on the speed at which the capillary sticks absorb the room fragrance. Within 1 - 2 hours of insertion the Eau de Parfum will have been absorbed to the height of the lid. After 5 - 7 days the liquid will have reached its highest level, approximately 10 - 15cm above the wooden lid.
In general the life expectancy of LINARI room fragrances is 6 months, however they can last much longer. The evaporation rate, and therefore the average life expectancy is dependent on atmospheric conditions. Low humidity, low air pressure, high temperature or any combination of these conditions may decrease the evaporation time.
