Reeds do not last forever. Over time they can become clogged with fragrance oil and dust, which makes it harder for them to draw the liquid up and release scent into the room. If your diffuser seems weak, replacing the reeds is often the quickest and most effective fix.

Placement is one of the most important factors in getting the best performance from your reed diffuser. For the best results, place your diffuser in an area with gentle natural airflow such as a hallway, living room or bathroom. Natural movement in the room helps carry the fragrance through the space.

Avoid placing your diffuser near strong draughts, air conditioning vents, ceiling fans or constantly opening doors and windows. Strong airflow causes the oil to evaporate too quickly, shortening the life of your diffuser and reducing scent performance.

Avoid direct sunlight and heat sources such as radiators. Heat and light accelerate evaporation and will significantly shorten the life of your fragrance oil.

If your diffuser is placed on a windowsill it will use the oil more quickly due to temperature changes and airflow.

For larger rooms, one diffuser may not be enough. Consider placing two diffusers at different points in the space for even scent distribution.

A single diffuser may not be enough for a large room or open-plan space. In bigger areas, the scent can feel much weaker simply because there is more air to fragrance. In this case, you may need more than one diffuser or a stronger home fragrance option.

Sometimes the diffuser is working perfectly well, but you have become used to the fragrance and notice it less. This is very common with home fragrance. Try leaving the room for a while and coming back, or ask someone else if they can still smell it.

Turning the reeds can refresh the scent because it exposes the saturated ends to the air. This should be done carefully and not too often, as frequent turning can use the liquid more quickly. It is best done over a protected surface in case of drips

Some fragrances are naturally lighter and fresher, while others are deeper and more noticeable. Citrus, linen and soft floral scents can feel more subtle than richer notes such as amber, spice or dark fruits. If you prefer a stronger scent, it may be worth choosing a more intense fragrance.

If the liquid is running low, the reeds are old, or the scent remains weak after changing position, it may simply be time for a refill and fresh reeds. Replacing both usually gives the best result and helps your diffuser perform properly again.
