Diffuser Oil Refills

Essential oils are single-source plant extracts produced through distillation or cold pressing. Diffuser oils are blended compositions engineered for consistent scent, stronger scent throw, and a wider range of scent profiles than any single botanical can deliver on its own. Aroma Country diffuser oils are fragrance oils formulated specifically for home diffusion.

In a cold-air diffuser on a moderate setting, an 8.5 oz bottle generally lasts 2 to 4 months. Smaller 4 oz bottles generally last 4 to 8 weeks, and 24 oz bottles can last 6 months or longer. Run time, intensity, room size, and air circulation all affect actual duration. Unopened bottles have a shelf life of approximately 2 years when stored in a cool, dry location.

For cold-air diffusers, interval settings (for example, 10 minutes on, 20 minutes off) are common and help maintain consistent scent without oversaturating the space. Ultrasonic diffusers are often run for 30 to 60 minute sessions. Adjust based on room size and personal preference.

Yes. Every Aroma Country diffuser oil is formulated to work across cold-air, ultrasonic, and reed diffuser systems, so you can use the same scent throughout the home regardless of which device is in each room. Cold-air diffusers use the oil undiluted, ultrasonic diffusers combine 5 to 10 drops per 100 ml of water, and reed diffusers absorb the oil passively through the reed bundle.
