If you’re a reed diffuser enthusiast who loves to experiment with different scents and make your own custom blends, this 100-pack of sticks is the perfect starting point for you.
The main benefit of these reeds is their excellent capillary action, which means they pull the oil up efficiently for a stronger, more consistent fragrance throw. For example, you won’t have to flip the sticks as often to refresh the scent in your room. They are also highly absorbent, helping you get the most out of your precious essential or fragrance oils without waste.

You won’t have to constantly flip the reeds to get the aroma going again.
Beyond performance, the bottle itself is a stylish piece of home decor.

Buyer’s Guide: 3 Key Factors to Consider
Choosing the right carrier oil is crucial for a long-lasting and fragrant home. Don’t just grab the first bottle you see; focus on these key aspects to get the best value and performance from your reed diffuser.
Viscosity and Wick Absorption
The thickness, or viscosity, of the oil directly impacts how well it travels up the reeds. A thin, low-viscosity oil like fractionated coconut oil absorbs quickly, releasing scent faster. A slightly thicker oil provides a more controlled, steady diffusion. The best oils strike a perfect balance, ensuring consistent fragrance flow without clogging the reeds.
Scent Neutrality and Purity
Your carrier oil should be a blank canvas. Its job is to carry the fragrance oils, not compete with them. Always opt for odorless, pure, and high-quality oils. Avoid cheap, unrefined oils that have their own natural scent, as they can muddy your expensive essential or fragrance oil blends and shorten the overall lifespan of the scent.
Longevity and Evaporation Rate
A good carrier oil evaporates slowly. This is what makes your diffuser last for months, not weeks. Look for oils that are known for their stability and low evaporation rates. While mineral oil is a common choice for this reason, many natural alternatives like fractionated coconut oil offer excellent longevity without the synthetic feel, giving you a lasting aromatic experience.
Frequently Asked Questions
Q1: Can I use water instead of a carrier oil in my reed diffuser?
A1: We don’t recommend it. Water evaporates too quickly, doesn’t effectively carry most fragrance oils, and can lead to bacterial or mold growth in your diffuser vase, which can ruin the scent and create a mess.
Q2: How often should I flip the reeds in my diffuser?
A2: Flip the reeds when you first set up your diffuser to prime them, and then about once a week thereafter. Flipping them refreshes the scent intensity. Always flip them over a trash can or paper towel to avoid drips.
Q3: Why has my diffuser stopped emitting scent?
A3: This is usually because the reeds are clogged with dust or dried oil. Try replacing them with new reeds. If that doesn’t work, the carrier and fragrance oils may have fully evaporated, meaning it’s time to refresh the entire mixture.
Q4: Is it safe to use baby oil as a carrier oil?
A4: While baby oil (a form of mineral oil) works from a functional standpoint, it is often scented. This added fragrance will clash with your intended scent. For the purest results, it’s better to use an unscented, dedicated carrier oil.
Q5: Can I mix different carrier oils together?
A5: Absolutely! Experimenting with blends can be a great way to customize performance. For example, mixing a fast-absorbing oil with a slower-evaporating one can help you fine-tune the scent throw and longevity of your diffuser.
Final Verdict: Which One Should You Buy?
For a foolproof, high-performance option that works with any fragrance, **fractionated coconut oil** is our top recommendation. Its perfect balance of low viscosity, complete odorlessness, and natural composition ensures strong, consistent scent diffusion and a long lifespan. It’s the ideal choice for anyone seeking a reliable, natural, and effective base for their reed diffuser creations.
