Frequently Asked Questions (FAQs)

1. Can I get refills for diffusers?

Simply Reed Diffuser Refills are made with the finest quality fragrances and are an extremely effective way to fragrance your home. Simply reed diffuser refills are long-lasting with each 200ml bottle containing enough fragrance to last 3-4 months.

2. What can I use to refill my diffuser?

Mineral oils like sweet almond oil or safflower oil tend to be the most popular because they're thin enough to travel up the diffuser reeds (or bamboo skewers!), allowing your room to quickly fill with the scent of your choice.

3. Can you use Air Wick refills in a diffuser?

Can I use other product refills in my Air Wick Essential Mist Aroma Diffuser? Safety evaluation and toxicology reviews have not been performed on any other refills other than those designed and created by Air Wick, therefore it is not advised to use other refills with this diffuser.

4. Can you refill plug-in air fresheners with essential oils?

Fill the empty bulb 1/3 of the way with the essential oil or essential oil blend. Fill the rest with water. (Notice how the oil floats along the top). Now, simply add the wick back onto the bulb and re-attach to your plug-in.
