How Long Do Reed Diffusers Last & How To Make Them Last Longer

Reed diffusers have become a popular choice for home fragrance enthusiasts, offering a subtle and continuous aroma that can transform any room into a pleasant oasis. But like any other scented product, reed diffusers have a finite lifespan. In this blog post, we'll explore the factors that influence how long reed diffusers last and provide you with tips on how to extend their longevity. Whether you're a seasoned reed diffuser aficionado or just curious about incorporating them into your home, this guide will help you make the most of these delightful scent dispensers.

How Long Do Reed Diffusers Last?

Reed diffusers are renowned for their longevity compared to other home fragrance options such as candles. On average, you can expect a well-maintained reed diffuser to last anywhere from 2 to 4 months. At Quiet Blue, our small diffusers easily last 4 - 5 months, whilst our XL diffusers last between 9 - 12months. However, several factors can influence the exact duration of your reed diffuser's lifespan:

1. Fragrance Oil Quality

  • Essential Oils vs. Synthetic Oils: Natural essential oils tend to evaporate more slowly than synthetic fragrance oils, making them a great choice if you want your reed diffuser to last longer. At Quiet Blue, we use natural oils within our diffusers to maximise the longevity of scent, whilst being kind to your body and planet.
  • Oil Concentration: High-quality fragrance oils often have a higher concentration of scent compounds. Look for reed diffusers with a fragrance oil concentration of at least 20% for a longer-lasting experience.

2. Room Temperature and Humidity:

  • Temperature Effects: High temperatures can cause the fragrance oil to evaporate quickly, shortening the life of your reed diffuser. Try to keep the room temperature between 18°C to 24°C (65°F and 75°F).
  • Humidity Matters: Low humidity levels can also accelerate evaporation. Using a humidifier in dry climates can help maintain the scent for a more extended period.

3. Reed Stick Quality:

  • Natural vs. Synthetic Reeds: Natural reed sticks are generally more porous and absorbent than synthetic ones, allowing for better scent diffusion. Opt for natural rattan or bamboo reeds for optimal performance.
  • Length and Diameter: The length and diameter of the reed sticks can affect the rate at which fragrance oil travels up the reeds. Longer, thicker reeds may release the scent more slowly.

4. Fragrance Concentration:

  • Options for Customisation: Some reed diffusers offer the flexibility to adjust the number of reed sticks used, allowing you to control the intensity of the scent and potentially extend the diffuser's lifespan. The more reed sticks used the greater the intensity - through this will reduce the lifespan of the diffuser.
  • Dilution: If you find the scent too strong, consider diluting the fragrance oil with a neutral carrier oil to slow down the evaporation rate. Jojoba or sweet almond oil are good choices, as they don’t evaporate and have neutral scents.

5. Frequency of Reed Flipping:

  • Scent Refresh: Flipping the reed sticks once a week helps refresh the fragrance by exposing the saturated end to the room. This simple maintenance step can significantly extend the life of your reed diffuser.

6. Room Size:

  • Multiple Diffusers: In larger spaces, consider using multiple reed diffusers strategically placed throughout the room to ensure even coverage. This not only enhances the scent experience but also extends the life of each individual diffuser. Explore our XL Diffusers for large open plan spaces.

7. Air Circulation:

  • Fan or Ventilation: Proper air circulation within the room helps disperse the fragrance evenly. Using a fan or opening windows periodically can prevent the scent from settling in one area and help the reed diffuser last longer.

Understanding these factors will allow you to choose the right reed diffuser, take appropriate precautions, and make informed decisions to maximise its lifespan. By paying attention to the quality of ingredients, environmental conditions, and regular maintenance, you can enjoy the delightful aroma of your reed diffuser for an extended period.

How to Make a Reed Diffuser Last Longer

Now that we've discussed the factors that determine the lifespan of reed diffusers, let's delve into some practical tips on how to make your reed diffuser last longer:

  • Choose High-Quality Products: Invest in a high-quality reed diffuser with premium fragrance oil. While these may be more expensive upfront, they often last longer due to their superior ingredients.
  • Optimal Placement: Find the perfect spot for your reed diffuser. It should be away from direct sunlight, heat sources, and drafts. A cool, shaded area with moderate humidity is ideal.
  • Proper Reed Care: When setting up your reed diffuser, make sure to immerse the reed sticks in the fragrance oil for about 15 minutes before flipping them. This allows the reeds to absorb the oil effectively. Afterward, flip the reeds weekly or as needed to refresh the scent.
  • Use Fewer Sticks: If you find the scent too overpowering or want to make the diffuser last longer, use fewer reed sticks. Fewer sticks will release the fragrance more slowly, extending the diffuser's lifespan.
  • Seal When Not in Use: When you're not enjoying the fragrance, consider sealing the diffuser with the original stopper or a cork to prevent unnecessary evaporation.
  • Store Fragrance Oil Properly: If you have extra fragrance oil, store it in a cool, dark place with the cap tightly sealed. This will help maintain its potency for future use.
  • Replenish When Needed: Some reed diffusers come with refillable bottles. When the fragrance starts to fade, you can refill the bottle with a matching fragrance oil to extend the diffuser's lifespan.
  • Experiment with Room Size: If you're using reed diffusers in a larger space, consider adding more diffusers strategically placed throughout the room. This will ensure a consistent fragrance without overworking a single diffuser.
  • Clean the Bottle: Over time, dust and debris can accumulate in the diffuser bottle, affecting its performance. Clean the bottle with a soft cloth or paper towel before refilling it with oil.
  • Use Diffuser Base or Reeds: Some reed diffusers come with a base that helps control the release of fragrance. Alternatively, you can use reeds with varying levels of porosity to control the intensity of the scent.


Reed diffusers are a wonderful way to infuse your living space with captivating scents that can evoke feelings of relaxation, comfort, and tranquillity. While their lifespan may vary depending on factors such as oil quality and environmental conditions, you can maximise their longevity with proper care and maintenance.

By following the tips outlined in this guide, you can enjoy your favourite fragrances for an extended period, making your reed diffuser a cost-effective and delightful addition to your home's ambiance. So, go ahead, select your favourite scents, set up your reed diffusers, and relish in the long-lasting aroma they bring to your surroundings.
