Frequently Asked
Do I need to add water?
No. The ECHO is fully waterless — it atomizes pure fragrance oil directly. That means no daily topping up, no humidity, no mineral buildup, and a scent that doesn't get watered down.
Do I need ductwork or an HVAC system?
No. The ECHO is completely free-standing. Plug it into a standard outlet and it diffuses straight into the room. No ductwork, no installation.
Will one really cover 1,500 sq ft?
In open space, yes — a main floor with connected living, dining and kitchen is exactly its range. Walls and closed doors will limit it, so for separate bedrooms you may want to reposition it or add a second unit.
Is there any flame or heat?
None. No wick, no flame, and no hot surfaces — the ECHO runs entirely cold. Like any diffuser holding fragrance oil, keep it upright on a level surface.
How loud is it?
Quiet enough for a bedroom or an office call. You'll notice the fragrance long before you notice the unit.
What fragrance oils does it use?
The ECHO is designed for Mila Marie Scents 120ml and 200ml luxury fragrance oils. Your bundle package includes your choice of 1, 2, or 3 signature 120ml fragrance oils (each bottle lasting up to 30 days of consistent, hotel-grade scenting). No dilution or water needed.
What if it isn't right for my space?
You have 30 days. Send it back for a full refund with no restocking fee.
