ILLUME offers a range of refill options designed to fit seamlessly into your existing glass jars and diffuser bottles. By mastering the refill process, you can keep your home smelling amazing without constantly buying new containers. Let's dive into the step-by-step instructions.
Why Choose ILLUME Candle Refills?
Refills are an eco-friendly and budget-conscious choice for candle lovers. Instead of discarding beautiful glass jars after the wax is gone, you can simply insert a new refill and continue enjoying the scent. ILLUME's refillable system is designed to be user-friendly, making it easy to switch scents or replenish your favorites.
For example, the Citrus Crush Boxed Glass Candle Refill and the Rhubarb Honey Baltic Glass Candle are popular choices that fit perfectly into their respective glass containers. By using refills, you reduce waste and often save money compared to buying a whole new candle.

- Eco-friendly: Less glass waste.
- Cost-effective: Refills are usually cheaper than new candles.
- Convenient: Switch scents without buying new jars.
Step 1: Prepare Your Glass Jar or Diffuser
Before inserting a refill, ensure your glass jar is clean and completely cool. If there is leftover wax from a previous candle, you can place the jar in the freezer for a few hours to make the wax shrink and pop out easily. Wipe the inside with a paper towel to remove any residue.
For reed diffusers, like the Hidden Lake Refillable Aromatic Diffuser, remove the old reeds and empty any remaining oil. Rinse the bottle with warm soapy water and let it dry completely before adding the new refill oil.
- Freeze jars to remove leftover wax.
- Wash diffuser bottles with mild soap and dry thoroughly.
Step 2: Insert the Candle Refill Correctly
Most ILLUME candle refills come in a boxed glass format. To insert, simply place the refill into your clean glass jar. Ensure it sits evenly at the bottom. If the refill is slightly smaller, you can use a small amount of adhesive putty to secure it in place.
For a seamless look, the Blackberry Absinthe Refillable Aromatic Diffuser is a great choice. Simply pour the refill oil into the empty diffuser bottle, insert the reeds, and flip them after a few minutes to saturate them.
- Make sure the refill is centered.
- For diffusers, flip reeds once or twice to start the scent throw.
Step 3: Burn Your Refill Candle Safely
Once your refill is in place, trim the wick to about 1/4 inch before lighting. On the first burn, let the candle melt the entire top layer to prevent tunneling. This ensures an even burn and maximizes the life of your refill.
Always place the candle on a heat-resistant surface and never leave it unattended. With proper care, your refill will provide hours of fragrance.
- Trim wick to 1/4 inch before each burn.
- Allow a full melt pool on the first burn.
Step 4: Refill Your Reed Diffuser
Reed diffuser refills are even simpler. After cleaning your diffuser bottle, pour the entire refill oil into it. Insert the reeds and allow them to soak for a few minutes. Flip the reeds to refresh the scent whenever it fades.
The Hidden Lake Diffuser Refill is a popular choice for its calming scent. You can also use the Balsam & Cedar Pura Fragrance Refill if you have a Pura diffuser.
- Flip reeds weekly for a consistent scent throw.
- Keep diffuser away from direct sunlight to prevent oil evaporation.
Refilling your ILLUME candles and diffusers is a rewarding practice that saves money and reduces waste. By following these simple steps, you can enjoy your favorite scents again and again.
