Frequently asked questions

WHAT GOES INTO AROMATECH DIFFUSER OILS?

Our oils are crafted in New York with a balance of natural ingredients, plant-derived elements, and modern synthetics. Each formula is developed with care and precision, shaped over time to diffuse cleanly and hold its character in the air. Every element is selected with intention, from sourcing to structure to performance in your home.

Formulations are free from parabens, sulfates, glycols, petrochemicals, and synthetic colours, and meet the highest standards for safe use around people and pets.

HOW DO I CHOOSE A SCENT FOR MY SPACE?

Scent moves with the day and the season. Fresh citrus, tea, or soft florals for lighter moments. Woods, vanilla, and deeper notes as the space settles in. You may keep one scent throughout, or change it as the rhythm of the day changes.

If you’re unsure where to begin, take our scent quiz for a self-guided discovery journey, start with our discovery kits, or explore scents by family. You can also connect with a scent advisor to find what fits your space.

HOW SHOULD I TEST A SCENT?

When your scent arrives, give it time. Place it in your diffuser and let it move through the space. Notice how it opens, settles, and becomes part of the room.

Let it live with you for a few days. Morning light, evening quiet. The same scent can feel different as the day shifts.

If it’s not right, returns are simple within 30 days. Many choose to subscribe, building a personal library of scents over time, each one experienced, finding its place.
