The concentrated formula means you get maximum scent throw from each refill, stretching your money and ensuring a consistently pleasant fragrance throughout your home.

FAQ

What size are the refill bottles?

The refills come in 10ml bottles, providing a concentrated dose of fragrance. This is typically enough to last approximately 4-6 weeks depending on the room size and reed diffuser base used.

How many reeds do I need with these refills?

You’ll generally require between 5-10 reeds per refill bottle for optimal scent diffusion. Experiment to find what works best in your space – more reeds create a stronger aroma.

What type of fragrances are available?

We currently offer refills in popular scents like Lavender, Vanilla, Citrus Burst and Eucalyptus Mint. Amazon UK regularly adds new fragrance options to their reed diffuser selection.

Do I need to add anything else to the refill?

No, you simply pour the liquid directly into your chosen reed diffuser base. The concentrated formula is designed for immediate use with standard bases – no mixing required.

How long does a single refill last?

The longevity of a refill depends on several factors including room size, ventilation, and the number of reeds used. Expect approximately 4-6 weeks of consistent fragrance output from a single 10ml bottle.

Can I use these refills with any reed diffuser base?

While designed for compatibility, we recommend using bases specifically made for concentrated reed diffuser oils to achieve the best results. Check Amazon UK for bases that support small refill sizes.

What is the shelf life of the refills?

The refills have a shelf life of approximately 12-18 months when stored in a cool, dark place away from direct sunlight. Once opened, we recommend using them within 6 months for optimal fragrance strength.

Are these refills safe to use around pets?

Most reed diffuser oils are considered pet-safe when used responsibly and in well-ventilated areas. However, always monitor your pet’s reaction and avoid direct contact with the oil or reeds.

What if the scent fades quickly?

Scent diffusion naturally diminishes over time as the fragrance evaporates. To refresh the scent, simply add more reeds to your diffuser base or consider using a reed diffuser rejuvenator (available on Amazon UK).

Where can I buy a compatible reed diffuser base?

A wide selection of reed diffuser bases are available for purchase on Amazon UK, ranging in price and materials. Consider the size of the bottle when choosing your base to ensure optimal performance.
