At a Glance
Is the Casa Right for You?
Coverage
Up to 5,500 sq ft — whole homes, vacation rentals, boutique commercial spaces.
Setup
HVAC-integrated for whole-property consistency, or standalone in one room.
Not for You If
You're scenting one room or open living area — the Max covers that without the extra investment.
What "Whole-Home" Actually Means Here
The Scentia Casa is our flagship diffuser, and the number that matters most is coverage: up to 5,500 sq ft, or roughly 52,972 cubic feet of air volume. That's the result of a pump upgrade that more than doubled the unit's original range — the models previously sold as the SC2000 and SC5000 have been consolidated into this single, more powerful Casa. If you've seen those model numbers referenced anywhere, they're historical; the current product is simply the Scentia Casa.
In practical terms, 5,500 sq ft is enough for a full single-family home across multiple floors, a vacation rental property, or a boutique hotel, spa, or retail space that wants consistent fragrance throughout rather than a strong scent near one diffuser and nothing everywhere else.

Casa vs. Max: Which Coverage Do You Need?
One open room
The Max (up to 1,500 sq ft) is enough, and the more portable, lower-commitment choice.
Full home, multiple floors
The Casa is built for this — HVAC integration carries scent evenly through every vent in the house.
Rental or commercial property
The Casa's standalone mode covers large single spaces without ductwork access.
HVAC-Integrated or Standalone: How to Choose
The Casa works either way, and neither is a compromise. Integrated into your HVAC ductwork, it distributes fragrance evenly through every vent in the house — the closest thing to true whole-home consistency, since the scent travels the same paths as your heating and air conditioning already do. It's the setup most vacation rental hosts and homeowners choose when they want every room to smell the same, not just the room the diffuser happens to sit in.
Standalone mode skips the ductwork entirely — you place the unit in a central location and it covers its full range from there. It's simpler to set up, doesn't require any access to your HVAC system, and still handles a genuinely large area on its own. If you're renting, or you just don't want to deal with ductwork, standalone is the more practical starting point.
Control is the same either way: Bluetooth app control with a touchscreen on the unit, 9 adjustable scent intensity levels, custom scheduling so you can set it once and let it run, and real-time oil level monitoring so you always know how much is left in the 200ml bottle before you're caught without any.
Frequently Asked Questions
How much space does the Scentia Casa actually cover?
Up to 5,500 sq ft, or roughly 52,972 cubic feet of air volume, following a pump upgrade that more than doubled its original coverage. That's enough for a full single-family home, a vacation rental, or a small boutique commercial space — well beyond what the Max (1,500 sq ft) or Pod (500 sq ft) are built for.
Do I need the Scentia Casa, or would the Max be enough?
If you're scenting one open-concept living area, the Max covers that well on its own. The Casa makes sense once you want consistent fragrance across an entire home — multiple rooms, floors, or a layout the Max's 1,500 sq ft range can't reach evenly.
Does the Scentia Casa have to be connected to HVAC?
No. It works either integrated into your HVAC ductwork for even distribution through every vent, or as a standalone unit in one location. HVAC integration is the better choice for true whole-home consistency; standalone is simpler to set up and still covers a large area on its own.
How often do I need to refill the Scentia Casa?
The 200ml bottle typically lasts a few weeks depending on the size of the space and the intensity level you run. Real-time oil level monitoring in the app shows exactly where you stand, so you're never caught out.
Is the Scentia Casa suitable for a business?
Yes — the Casa is a common fit for boutique hotels, vacation rentals, spas, and other commercial spaces that need consistent, whole-property fragrance rather than a single-room device.
