Important Note: Always handle essential oils with care. Avoid direct skin contact and keep out of reach of children and pets. Use in well-ventilated areas and avoid placing diffusers on polished or porous surfaces that may be damaged by oil spills.

1. Cap and Stopper: Ensuring a Secure Seal

The cap and stopper play a critical role in preserving the integrity of your diffuser. A well-fitted seal prevents leakage and minimizes premature evaporation of essential oils, which can reduce both scent longevity and effectiveness.

• Material Options: Caps and stoppers are commonly made from wood (e.g., rattan or bamboo), plastic, or metal. Wooden stoppers are popular for their natural aesthetic and compatibility with reed diffusers.
• Functionality: The stopper must fit snugly into the bottle neck to maintain pressure balance and reduce spillage, especially when flipping the reeds.
• Maintenance Tip: Periodically inspect the stopper for warping or cracking, especially if using oils with high alcohol content, which can degrade certain materials over time.

2. Reed Length and Quantity: Optimizing Scent Diffusion

The reeds are the heart of the diffusion process. Their length and number directly influence how quickly and strongly the fragrance disperses into the air.

• Optimal Length: Reeds should extend from the bottom of the bottle to well above the rim—typically 20–25 cm for a 400 ml bottle. This ensures sufficient oil absorption and effective evaporation from the exposed ends.
• Recommended Quantity: For a 400 ml bottle, 5 to 7 reeds provide balanced diffusion. Use fewer reeds for a subtle scent or more for a stronger aroma.
• Adjustment Strategy: Flip the reeds weekly to refresh the scent. Replace them every 1–2 months or when they become clogged or overly saturated.
• Material Insight: Rattan reeds are preferred due to their natural capillary action, which efficiently draws oil upward for even diffusion.

3. Cleaning: Preparing for Reuse or Scent Changes

Proper cleaning is vital when switching fragrances or storing the bottle long-term. Residual oils can mix and alter new scents or cause clogging.

• Full Cleaning (Scent Change): Wash the bottle with warm, soapy water and a bottle brush. Rinse thoroughly and allow it to dry completely before refilling.
• Quick Rinse (Same Scent): If reusing the same fragrance, a simple rinse with warm water is sufficient to remove dust or debris.
• Deep Cleaning Tip: For stubborn oil residue, soak the bottle in a mixture of water and white vinegar or use isopropyl alcohol, then rinse well.
• Drying: Always air-dry the bottle upside down on a clean towel to prevent moisture buildup, which can dilute new oils.

4. Refilling: Cost-Effective and Sustainable Use

One of the main advantages of a 400 ml reed diffuser is its refillability, making it an eco-friendly and economical choice.

• When to Refill: Top up the bottle when oil levels drop below 1–2 inches to maintain consistent diffusion.
• Refill Process: Remove reeds temporarily, pour in new oil, reinsert reeds, and flip them after 1 hour to activate diffusion.
• Reed Replacement: Add fresh reeds during refills if the old ones are darkened or less effective. Saturation reduces capillary action over time.
• Oil Compatibility: Use high-quality diffuser base oils or essential oil blends designed for reed diffusers to ensure proper viscosity and safety.

Component	Recommended Specification	Maintenance Frequency	Tips for Optimal Performance
Cap/Stopper	Snug-fitting, material-compatible (wood/plastic)	Inspect monthly	Replace if cracked or loose to prevent evaporation
Reeds	5–7 rattan reeds, 20–25 cm long	Flip weekly; replace every 4–8 weeks	Flip reeds to refresh scent; increase number for stronger aroma
Bottle Cleaning	Warm soapy water or vinegar solution	Every refill or scent change	Air-dry completely to avoid oil dilution
Refilling	High-quality diffuser oil or essential oil blend	When oil level is low (approx. 1–2" remaining)	Use fresh reeds for best absorption and scent throw

Expert Tip: Place your 400 ml diffuser in a well-ventilated area away from direct sunlight and heat sources. UV rays and high temperatures can degrade essential oils and weaken glass over time, reducing both scent quality and bottle lifespan.

Additional Maintenance Recommendations

• Label your diffuser bottles if using multiple scents to avoid confusion during cleaning and refilling.
• Store unused reeds in a sealed container to prevent dust accumulation and premature oil absorption.
• Keep a log of refill dates to track oil consumption and reed replacement schedules.
• Consider using a diffuser tray or mat to protect surfaces from accidental spills or drips.
• For extended storage, empty the bottle, clean thoroughly, and store with the cap off to prevent odor buildup.

By following these detailed specifications and maintenance guidelines, your 400 ml diffuser glass bottle will deliver consistent, long-lasting fragrance while maintaining its aesthetic and functional quality. Regular care not only enhances performance but also supports sustainable usage, making your aromatic experience both enjoyable and environmentally responsible.
