Which Aroma Max Diffuser Is Right for You?
Choosing a scent diffuser comes down to one main question: how much space do you need to cover? Aroma Max makes four cold-air and HVAC diffusers, each built for a different footprint. Here's a simple guide to picking the right one.
Quick comparison by square footage
- Mini Pro — cold-air, up to 900 sq ft. Our top seller. Great for bedrooms, living rooms, offices, and reception areas.
- Mini Plus — cold-air, up to 900 sq ft with a larger oil capacity for longer run time between refills.
- Villa Max — HVAC, up to 1,500 sq ft. Connects to your HVAC to scent a whole home or small business evenly.
- Grand Palazzo Max — commercial-grade HVAC, up to 2,300 sq ft. Programmable schedules and intensity for larger businesses.
Cold-air vs HVAC: what's the difference?
Cold-air units (Mini Pro and Mini Plus) sit in the room and diffuse a fine, dry mist directly into the space — perfect for single rooms and smaller areas. HVAC units (Villa Max and Grand Palazzo Max) connect to your heating and cooling system and push scent through your existing vents, covering much larger areas evenly and invisibly.
How to choose
One or two rooms (up to 900 sq ft): go with the Mini Pro or Mini Plus.
A whole home or small business (up to 1,500 sq ft): the Villa Max HVAC diffuser is the sweet spot.
A large business, retail floor, gym, or venue (up to 2,300 sq ft): the Grand Palazzo Max is built for commercial coverage.
