The system
You'll never see the machine.
One quiet unit outside. A hidden path through the walls and ceiling. Clean air in every room, with nothing to look at and nothing to hear.
It lives on the balcony. It works for the whole home.
The unit sits outside, out of sight and out of earshot. It draws in outside air and strips it of what the city adds: dust, smoke, and the fine particles you would otherwise breathe.
What crosses your threshold is only the good part of the day.
Ducting you'll forget the day it's finished.
Insulated ducts run through the walls and ceilings you already have: sized, sealed, and balanced so air moves in silence. No exposed pipes. No hum behind the plaster.
Installed with care. Hidden with intent.
The rest disappears overhead. A whisper, not a wind.
Everything inside your home is concealed above the ceiling. Clean air arrives evenly through discreet outlets in every room: no drafts, no cold spots, no noise you'd ever notice.
It's the quietest thing in the house that never stops working.
The oal app
One glance. One number.
The app shows the air you're breathing right now, and what the system quietly did about it. No dashboards to study. No settings to fuss over. Just the number that matters, and the calm of watching it stay low.
