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?
Mila Marie Scents 200ml premium fragrance oils. Oils are sold separately, so you can pick the scent that suits the room. Build your diffuser system and save up to 25%.
What if it isn't right for my space?
You have 30 days. Send it back for a full refund with no restocking fee.

Most diffusers get hidden. Plastic, clinical, a cloud of steam on your side table — something you tuck behind a plant and hope nobody looks at.
The ECHO was designed to sit in plain sight. Three finishes to match your room, no visible mist, no water tank, no cord chaos. It looks like something you chose, because it is.
And it works like the systems in luxury hotels: dry cold-air nano-mist that carries real fragrance across the whole room instead of dumping humidity into one corner.

Advanced Cold-Air Nano-Mist Technology
Professional-grade cold-air diffusion disperses fragrance without heat or water. No dilution of the fragrance, no residue or buildup, no added humidity — just long-lasting, consistent scent. The same technology used in luxury hotels and premium retail environments.
Smart Bluetooth Control
Full control from your phone. Set intensity, build schedules, and monitor usage through the app — on before you walk in, gentle overnight, off entirely while you're away.
