This ready to use solution is to be added to an existing diffuser bottle. When you buy a refill, you will also need to purchase new reeds as the reeds are not reusable. Refilling your diffuser means that you don't need to throw away bottles that you have that you love the look of. This also saves you money and reduces your household waste.
Simply wash out your diffuser bottle, ensuring that it is completely dry, fill it with your refill bottle and then replace the reeds. You must take care when filling as the diffuser base is very damaging to surfaces. Refill over a sink and use a funnel. These are reusable and are sold seperately for just £1.
