Choosing the right diffuser depends on your space—its size, ceiling height, and how air moves. Our standalone models are ideal for rooms up to 5,000 sq.ft through HVAC and offer full control over scent intensity and scheduling, either directly or through the Whiffed Aromas app. For larger areas up to 15,000 sq.ft, our commercial diffusers deliver seamless, large-space scenting, especially in high-ceilinged or open-plan environments. Every unit is designed to let you fine-tune the fragrance experience to suit your space and your mood.

More simple, you can also choose machines based on capacity:

• 10ml: Perfect size for Mobile One or Mobile Two

• 150ml: Works for either Fusion 200 (200ml) or Twosome (100ml).

• 500ml: Fills up Fusion 500 (500ml) and Polymer One (400ml) to satisfaction, with more left for later.

There are plenty of ways to diffuse scent—but only cold-air nebulizers deliver pure, undiluted fragrance at scale. Unlike ultrasonic diffusers, they don’t rely on water or heat, preserving the oil’s integrity while producing a dry, ultra-fine mist that leaves no residue behind. If you want bold, clean scent that truly fills a space, cold-air diffusion is the gold standard.

Whiffed Aroma machines are made to be seen or blend in with your design. You can place them in a corner, a table top, or connect (compatible) machines to your HVAC with the included accessories with no technician required.
