Frequently Asked Questions
Are essential oil diffusers safe for pets?
Some essential oils (tea tree, eucalyptus, peppermint) are toxic to cats and dogs. If you have pets, check oil safety for your specific animal before diffusing. Lavender and chamomile are generally considered safer for most pets in diluted diffuser amounts — but consult a vet if uncertain.
How many drops of essential oil should I use?
For a 100–300ml diffuser: 3–5 drops. For 300–500ml: 5–10 drops. Start with fewer drops — a subtle scent is more pleasant than an overpowering one. Peppermint and eucalyptus are particularly potent; start with 2–3 drops.
