Our scent oils are compatible with all Aemster Diffusers, as well as other cold-air/nebulizing diffusers, ultrasonic diffusers, and scent stones. In Aemster Diffusers, the oils are used 100% pure and undiluted, releasing their full aromatic profile with only a tiny amount. This makes them both highly effective and economical. In ultrasonic diffusers, just a few drops are sufficient due to their high concentration. To experience the ultimate scent of the oils, we recommend using them in Aemster Diffusers.

We create our scent oils from the highest-quality essential and aroma oils. When an essential oil is known to be allergenic, unsustainable, or not cleared by the IFRA (International Fragrance Association), we use pure, safe synthetics as a responsible alternative. We are committed to regulations, adhering to strict health and environmental standards. All scent ingredients are IFRA-approved and meet safety guidelines.

Our scents are safe for use in living and working spaces, including around pets. However, animals may be more sensitive to fragrances, and since they cannot tell us if a scent feels pleasant to them, it’s always good to observe their behavior. Our scents are IFRA-certified (International Fragrance Association), which means they comply with globally recognized safety standards, developed through continuous scientific review and expert collaboration. These standards ensure that our scent oils are used safely and responsibly.

Please note: our scents are for ambient use only and should never be ingested.

You can use all our scent oil sizes (15 ml, 120 ml, and 500 ml) with your diffuser. Simply pour the oil into the inner bottle of the diffuser. The size of this inner bottle varies per diffuser, but you can always refill it from any bottle size.

The usage time of a bottle of Aemster scent oil depends on the diffuser, the intensity, and how often you turn it on. Our diffusers atomize the oil 100% pure and undiluted, so you only need a small amount to make a room smell wonderful.

You could say that an Aemster diffuser consumes an average of 0.16 ml per hour, making our diffusers among the most economical on the market. As an indication: with 6 hours of use per day, a 120 ml bottle will last approximately 4 months, and with 8 hours of use per day, approximately 3 months.

If you use the diffuser for less time or at a lower intensity, a bottle will of course last even longer.
