Know before you buy
While this formula is specifically designed for Castelbel and Portus Cale vessels, it can be used in any glass diffuser bottle. Ensure your existing bottle is clean and dry before adding the oil to maintain the integrity of the scent.
Because this is an oil-based, alcohol-free formula, it evaporates more slowly than standard alcohol-based diffusers. Depending on the number of reeds used and the airflow in your room, a 250 mL bottle generally lasts between three to six months.
Yes, the set includes new natural reeds for a reason. Over time, reeds become saturated and clogged with dust or fragrance oils, which prevents them from effectively wicking the scent into the air.
No, this fragrance is formulated to be delicate and airy, reminiscent of clean linen. If you find the scent too strong, simply remove a few reeds from the bottle to reduce the fragrance throw.
The oil is designed to be absorbed by the reeds and diffused into the air. However, you should always place your diffuser on a stable, level surface and avoid placing it directly on polished or painted wood, as oil spills can cause surface damage.
