Bath & Body Works makes a home fragrance product called Wallflowers. It is a fragrance unit that plugs into an electrical outlet and releases a scent. The bulbs on the unit can be changed with a new scent or replaced with the same scent. A new refill bulb may be purchased. Some units have LED lights in them also, but the refill process for both is the same.
Remove the Bath & Body Works Wallflowers Home Fragrance unit from the electrical outlet. Check that there is no collection of dust or damage to the unit.
Hold the bulb on the bottom in 1 hand and the top of the fragrance unit in the other hand. Twist the bulb counterclockwise and pull the bulb out of the unit. Set the fragrance unit aside.
Remove refill bulb from store packaging. Twist cap from the top of the bulb counterclockwise to remove it. Insert the refill into the Wallflower unit and turn clockwise until it is snug. Plug the unit back into the outlet.
