Quick answer

To refresh your car's aroma, replace the oil bottle and wick in your Wave Car diffuser using the dedicated refill set — it takes under two minutes and keeps the scent consistent.

Why use the dedicated refill?

The Wave Car diffuser uses a specialized cartridge and oil blend to disperse fragrance evenly in a small, moving space. Using a non-dedicated oil or skipping the wick replacement can lead to weak scent or uneven diffusion.

The Original Blend Oil (30ml) is formulated for the car environment — it's not just any essential oil. The replacement wick ensures the oil wicks properly from the bottle to the diffuser's atomizer.

Step-by-step: Replace your car diffuser refill

  1. Remove the old oil bottle and wick: Turn off the diffuser. Gently pull the empty oil bottle out of the base. Unscrew the used wick from the bottle neck. Don't reuse an old wick — it can harbor dried oil residue that reduces fragrance throw.
  2. Insert the new wick into the fresh oil bottle: Take the new replacement wick (WAVECar diffuser専用替え芯) and push it firmly into the neck of the new Original Blend Oil bottle until it's snug. Ensure the wick is fully seated; a loose wick can leak oil into the diffuser base.
  3. Install the refill set into the diffuser: Place the oil bottle with the new wick into the diffuser base. Press down until it clicks into place. Turn the diffuser on and enjoy the refreshed scent. If the diffuser doesn't start, check that the bottle is fully clicked in — a partial connection prevents power from reaching the atomizer.
