Quick answer

Refilling your Diptyque reed diffuser is straightforward: purchase a recharge bottle of your favorite fragrance, remove the old reeds, pour the new oil into the original glass bottle, and insert fresh reeds for continuous scent.

Why refill instead of replace?

Refilling your Diptyque reed diffuser saves money and reduces waste. The original faceted glass bottle is designed to be reused—you only need to buy a recharge bottle of the same scent or a new one you love. The recharge bottle (like the 34 Boulevard Saint-Germain recharge) offers a more economical way to enjoy your signature interior perfume over time.

Steps to refill your Diptyque reed diffuser

  1. Remove the old reeds and empty the bottle: Take out all reeds from the glass bottle and discard them. Pour out any remaining fragrance oil (you can use it to refresh a small room by placing the oil in a dish). Rinse the bottle with warm water and mild soap, then dry it completely. Make sure the bottle is fully dry before adding new oil to prevent dilution or mold.
  2. Pour the new fragrance oil into the bottle: Open your Diptyque recharge bottle (e.g., the 34 Boulevard Saint-Germain recharge) and carefully pour the oil into the clean, dry diffuser bottle. Fill it to the same level as the original—usually near the neck of the bottle. Do not overfill; leave a small gap to avoid spills when inserting reeds.
  3. Insert fresh reeds and let them absorb: Place new reeds (or thoroughly cleaned old ones) into the bottle. Wait 5–10 minutes for the reeds to soak up the oil, then flip them to start the diffusion process. For a stronger scent, flip the reeds once a week. Flip reeds less frequently if you prefer a subtler fragrance; flipping too often can shorten the life of the oil.
