Cold-air nebulization uses pressurised air to break pure essential oil into a fine mist — no water, no heat. Because oil is never heated or diluted, the full aromatic and therapeutic profile is preserved. Traditional ultrasonic diffusers use heat and water which degrades the lighter, more volatile molecules that give an oil its character and potency.

Choose by the space you're diffusing into. The Nebula Large is built for studios, open-plan living areas, treatment rooms, and lounge spaces up to 75 m². The Nova Small is designed for personal use — bedrooms, home offices, reading nooks, and bathrooms. If you have a dedicated wellness or lounge room, the Nebula is your match.

Yes — they work with any pure essential oil. That said, the Sage Space terpene-enhanced blends are specifically formulated for cold-air nebulization, ensuring consistent viscosity and optimal dispersion. Using oils with carrier oils, additives, or synthetic fragrance is not recommended as they can clog the nebulizer over time.

Because there's no water involved, cleaning is minimal. Run a short cycle with a small amount of isopropyl alcohol (90%+) every 2–4 weeks to clear any oil residue from the nebulizer. No tank to scrub, no mineral deposits. Full cleaning instructions are included with your diffuser.

Absolutely — that's what it's designed for. Both diffusers operate whisper-quietly and won't interfere with your lounge's audio or vibration. For best results, start the diffuser 5–10 minutes before your session so the aroma is fully established in the room when you begin.

All Sage Space diffusers come with a 60-day money-back guarantee. If you're not satisfied for any reason, return it to us and we'll arrange a full refund — no questions asked. A 12-month manufacturer's warranty covers defects in materials and workmanship.
