La Duchessa Aromatherapy  •  180ml Value Refill  •  100% Alcohol-Free

Refill it. Don't rebuy it.

Breathe new life into the diffuser bottle you already own. La Duchessa's 180ml refill is a high-concentration, 0% alcohol fragrance oil that diffuses slowly and evenly for 60–90+ days — with none of the sharp fumes or rapid liquid loss you get from standard alcohol-based diffusers. It's formulated specifically for Singapore's tropical, air-conditioned indoor climate, so the scent throw stays consistent whether your room runs humid or cold.

One 180ml bottle refills a standard 50ml vessel up to 3–4 times, or a 100ml vessel up to 2 times — a more economical, less wasteful way to keep your home scented like a 5-star hotel.

Why choose the La Duchessa refill

• 0% alcohol formula — no ethanol or volatile diluents, so it diffuses gently without drying out prematurely.
• Extended 60–90+ day lifespan — slow capillary evaporation keeps the room scented for up to 3 months per fill.
• Built for tropical homes — viscosity and evaporation rate tuned for air-conditioned rooms and high humidity.
• Family & pet safe — gentle enough for continuous scenting in bedrooms, nurseries and living areas.
• Fast SG dispatch — shipped locally within 24–48 hours.

How to refill

1. Remove the reed sticks from your existing diffuser bottle.
2. Empty any remaining liquid and top up with La Duchessa refill oil to your preferred level.
3. Return the reed sticks, flipping them for a stronger initial throw if desired.
4. Flip the sticks every 1–2 weeks to refresh the scent intensity.

Product specifications

Good to know

Will this fit my existing diffuser bottle?
Yes — it's a universal refill oil that works with any standard 50ml–100ml reed diffuser vessel and reed sticks, not just La Duchessa-branded bottles.

Can I mix a new scent into leftover oil?
For the cleanest scent throw, we'd recommend using up or discarding leftover oil before refilling with a new scent, since mixing can dull the fragrance profile.

My reed sticks stopped throwing scent — do I need new ones?
Sticks can clog with dust or dried residue over time. Flipping them helps, but if the throw stays weak after flipping, swap in a fresh set of reed sticks.
