Place & Connect
Set each unit near your HVAC system and run the included tube into your supply duct. One unit per system is all you need.
Fill & Set
Add your favorite Scent A Filter oil to each 16 oz reservoir. Set your schedule and intensity using the touch screen or the Scent A Filter app.
Breathe & Forget
The unit atomizes fragrance through the tube into your supply duct, and your HVAC carries it to every room. Adjust anytime from the app.
Why Cold-Air Nebulizing Changes Everything
Unlike ultrasonic diffusers that dilute oils with water, our electronic diffuser uses pressurized air to atomize pure fragrance oil into micro-fine particles. A tube installed into your supply duct atomizes the scent directly into your HVAC airflow - delivering stronger, more consistent fragrance with zero residue.
- No water required - pure oil diffusion
- Preserves oil integrity (no heat degradation)
- Even distribution via tube into supply duct
- Compatible with all Scent A Filter oils
- Control from your phone with the Scent A Filter app
- Safe for kids, pets & sensitive airways
