Looking to keep your reed diffusers smelling fresh for longer? These refill concentrates offer a convenient way to maintain the beautiful fragrance of your favourite diffuser blends. Designed specifically for use with existing reed diffuser systems, these refills provide a concentrated dose of premium fragrance oil, extending the scent throw and ensuring consistent performance. Each bottle contains a generous amount, providing several weeks of continuous fragrance – perfect for creating a relaxing atmosphere throughout your home.
These refill concentrates are formulated to work seamlessly with standard reed diffusers, utilising a blend of high-quality fragrance oils designed to diffuse beautifully without clogging the reeds. They come in a variety of captivating scents, allowing you to refresh your space and create the desired ambiance. Remember to regularly trim your reeds for optimal performance and fragrance release – this is essential for maximising the lifespan of both the refill and your diffuser.
Selecting the right refill concentration allows you to tailor the intensity of the scent to your personal preference. Experiment with different reed types and diffuser vessels to discover what works best, but these refills are formulated to provide a strong, lasting fragrance. Ensure you’re using compatible reeds for the best results; coarser reeds generally require less oil than finer ones.
FAQ
What size are these refill concentrates?
Each bottle contains 100ml of concentrated fragrance oil. This provides approximately 4-6 weeks of continuous diffusion, depending on factors like room size and reed type.
How many reeds will a 100ml refill last with?
This varies significantly, but generally, a 100ml refill will provide between 4 and 6 weeks of consistent fragrance output. Factors such as reed density, placement, and room ventilation all play a role.
Can I mix different scents together?
While experimentation is encouraged, mixing fragrance oils directly can sometimes lead to unpredictable results. It’s recommended to start with small amounts and test the blend before using a full refill.
What type of reeds are best for these refills?
Most standard reed diffuser reeds will work effectively with these concentrates. However, coarser reeds generally require less oil than finer ones, so adjust accordingly based on your diffuser’s performance.
How do I clean my diffuser when switching to a new refill?
Empty the old oil completely from your diffuser vessel. Then, thoroughly clean the container with warm water and mild detergent – ensure all traces of residue are removed before adding the new refill.
Will these refills clog my reeds?
If you don’t regularly trim your reeds (every 2-4 weeks), they can become saturated and potentially contribute to a reduced fragrance throw. Trimming allows fresh air to flow through the reeds, maintaining optimal diffusion.
Do I need to add any other ingredients to these refills?
No, these concentrates are designed to be used undiluted within your reed diffuser system. Adding additional ingredients could compromise the fragrance and potentially damage the reeds.
How long will the scent last in a small room?
In a small room (approximately 10-15 square metres), you can typically expect the fragrance to last for 4-8 weeks with a single refill, depending on usage and ventilation.
What if the scent fades quickly?
Ensure your reeds are trimmed regularly – this is often the primary cause of fading. Also, check that the diffuser isn’t placed in direct sunlight or near drafts which can accelerate evaporation.
Are these refills suitable for use with ceramic diffusers?
Yes, these concentrates are formulated to be used with both glass and ceramic reed diffusers, but always ensure your ceramic vessel is heat-resistant before placing it on a surface.
