FAQS
How does an ultrasonic aroma diffuser work?
Ultrasonic diffusers use high-frequency vibrations to break water and essential oil into a micro-fine cool mist. No heat is involved — so the therapeutic compounds in your oil are never damaged or altered.
Fruik diffusers are whisper-quiet, BPA-free, and auto shut-off when the water runs out.
What is the difference between an ultrasonic diffuser and a reed diffuser?
- Ultrasonic diffusers use water + pure essential oils, actively disperse therapeutic compounds into the air, and let you control scent strength and switch oils anytime.
- Reed diffusers use fragrance oils drawn passively through reeds — constant scent, but no therapeutic benefit and no control.
How many drops of essential oil should I put in a diffuser?
- Small room (up to 150 sq ft): 3–5 drops
- Medium room (150–300 sq ft): 5–8 drops
- Large room (300+ sq ft): 8–12 drops
Where should I place my diffuser for the best results?
- Place on a flat, elevated surface — a table or shelf, not the floor
- Keep near the centre of the room, not pushed against a wall
- Avoid placing directly under an AC vent — it disperses mist too quickly
- For bedrooms, place 1–2 metres from where you sleep
- Keep away from books, electronics, and wooden surfaces sensitive to moisture
How long should I run my diffuser?
30–60 minutes on, 30 minutes off is ideal for most rooms. Continuous use beyond 3 hours can cause olfactory fatigue — where your nose stops noticing the scent — and make the space feel heavy.
Is it safe to run a diffuser overnight while sleeping?
Yes — Fruik diffusers are safe for overnight use:
- Use interval mode (cycling on/off), not continuous mist
- Choose calming oils: lavender, chamomile, frankincense, or vetiver
- Keep some room ventilation — a slightly open door or window is ideal
- All Fruik diffusers auto shut-off when the water runs out — no fire risk
Can I mix multiple essential oils in the diffuser?
Absolutely — blending is one of the best parts of aromatherapy. Keep total drops within the recommended range and add each oil separately into the water.

How do I clean my ultrasonic diffuser?
After each use: Empty remaining water and wipe inside with a soft dry cloth. Leave lid open to air-dry.
Weekly deep clean:
- Half-fill the tank with water + 5–10 drops white vinegar
- Run for 5 minutes, then empty and wipe dry
- Clean the ultrasonic disc with a cotton swab dipped in vinegar
My diffuser is producing less mist than before. How do I fix it?
Reduced mist output is almost always caused by mineral or oil residue on the ultrasonic disc. Try these steps:
- Clean the ultrasonic disc with a cotton swab dipped in white vinegar
- Switch to filtered or distilled water — hard tap water causes rapid mineral build-up
- Ensure the water level is not below the MIN line
- Check the mist outlet isn't blocked by dust or deposits
Are aroma diffusers safe to use around children and pets?
Around children: Use child-safe oils — lavender and chamomile are the gentlest. Avoid eucalyptus, peppermint, and rosemary around children under 6. Keep sessions short and ensure the room is ventilated.
Around pets: Many essential oils are toxic to cats and dogs — especially tea tree, eucalyptus, and citrus. Never diffuse in a sealed room with a pet. Always allow your pet an exit, and consult a vet before regular use around animals.
What is the difference between essential oils and fragrance oils?
- Essential oils are 100% natural — extracted directly from plants via steam distillation or cold pressing. They carry genuine therapeutic compounds with real aromatherapy benefits.
- Fragrance oils are synthetic blends made in a lab to smell like something. No therapeutic benefit, and often contain chemicals that cause sensitivity over time.
What is a cold-pressed oil and how is it different from an essential oil?
Cold-pressed oils are carrier oils extracted by mechanically pressing seeds, nuts, or fruit rinds — without heat. Examples: sweet almond, jojoba, rosehip, coconut oil. They are used to dilute essential oils for skin use and have their own skin benefits.
Essential oils are highly concentrated aromatic extracts — not the same as carrier oils. Always dilute in a carrier oil before applying to skin, or use in a diffuser with water.
What essential oil is best for sleep?
Lavender is the most researched essential oil for sleep — multiple studies show it reduces anxiety and improves sleep quality. Other excellent options:
Diffuse 30–60 minutes before bedtime. For deeper effect, dilute lavender in a carrier oil and apply to wrists or the soles of your feet.
What essential oils are good for stress and anxiety?
- Bergamot — uplifting yet calming; ideal for daytime anxiety
- Ylang Ylang — shown to lower blood pressure and heart rate
- Frankincense — promotes deep, slow breathing; excellent for meditation
- Clary Sage — powerful stress reducer, especially for hormonal tension
Diffuse during work or after a long day, or apply diluted to pulse points for on-the-go relief.
Which essential oils help with focus and concentration?
- Peppermint — increases alertness and mental clarity
- Rosemary — research shows it improves memory retention and recall
- Lemon — uplifting; reduces mental fatigue and improves mood
- Eucalyptus — clears the mind and opens airways
Which essential oils are good for headaches?
- Peppermint — contains menthol, a natural analgesic; dilute and apply to temples
- Lavender — reduces tension headaches by calming the nervous system
- Eucalyptus — helpful for sinus headaches; opens airways
- Frankincense — anti-inflammatory; useful for stress and tension headaches
Which essential oils support immunity and respiratory health?
- Eucalyptus — the most studied oil for respiratory support; opens airways, antiviral properties
- Tea Tree — powerful antimicrobial; great for diffusing during cold and flu season
- Peppermint — natural decongestant; helps clear blocked sinuses
Can I apply essential oils directly to my skin?
No — pure essential oils should never be applied directly to skin. They are highly concentrated and can cause irritation, burning, or sensitisation.
Always dilute in a carrier oil. Safe dilution ratios:
- Adults (body): 2% = 12 drops per 30ml carrier oil
- Adults (face): 1% = 6 drops per 30ml carrier oil
- Children / sensitive skin: 0.5% = 3 drops per 30ml carrier oil
What essential oils should I avoid during pregnancy?
Generally avoid during pregnancy:
Generally safer (after first trimester, low dilutions, with medical approval):
How long do essential oils last and how should I store them?
- Citrus oils (lemon, orange): 1–2 years
- Floral oils (lavender, geranium): 2–3 years
- Herbal oils (peppermint, eucalyptus, rosemary): 3–4 years
- Woody & resinous oils (frankincense, cedarwood, sandalwood): 4–8+ years — often improve with age
- Cold-pressed carrier oils: 12–24 months; refrigerate after opening
Storage tips:
- Store in a cool, dark place — away from sunlight and heat
- Keep caps tightly closed after each use
- Store upright in their original amber glass bottles
- Avoid bathrooms — humidity fluctuations degrade oils faster
