House Of Moseley Casablanca Porcelain Diffuser

This is a passive diffuser, meaning it relies on the porcelain material to absorb and naturally evaporate the fragrance oil into the air. It does not require electricity, heat, or water to function.

Because it uses passive diffusion, the scent throw is subtle and localized. It is best suited for smaller spaces like bathrooms, bedside tables, or home offices rather than large, open-concept living areas.

To keep the diffuser working effectively, you should avoid letting dust accumulate on the porcelain surface, as this can clog the pores. If you decide to switch fragrance oils, note that the porcelain may retain the scent of the previous oil, so it is best to stick to one fragrance per diffuser.

It is designed for standard fragrance or essential oils. However, thicker, resinous oils may not evaporate as efficiently through the porcelain, so lighter, thinner oils typically perform best.

Refill frequency depends on the ambient temperature and airflow in your room, but generally, a 50 ml capacity will last for several weeks of consistent, subtle diffusion.
