It reads both sides of the wall — continuously, indoor against outdoor — and chooses which of the three the room needs right now. Nobody has to touch it.


The system
Treat, verb — to put something through a process that changes it. A purifier strains the air already in the room and hands it back. Zuture does four things to it, and works out for itself which one the room needs.

Electrostatic plasma or medical-grade H13 HEPA takes the particles out — PM1, PM2.5, PM10, smoke, pollen, allergens.
Every purifier stops here.
Where it goes
One wall.
In a commercial building, filtration, ventilation and environmental control are three separate plant rooms. Here they are one wall-mounted unit, fitted through a single small opening, in any of four orientations.
Everything above, in a single unit.
Filtered outdoor air, pushed in continuously. Stale air leaves. It is the only way CO₂ and VOCs ever actually go anywhere.
ASHRAE 62.1 is the standard we design against.
Dew point is checked before a single cubic metre comes in, so nothing condenses. Positive pressure keeps unfiltered air from seeping back through the gaps.
No mould, no damp, no infiltration.

Everything above, in a single unit. Three plant rooms’ worth of work, on one wall.
How it works
Air is pulled through one filter after another. Here is each one, in order, and what it takes out.
Air in
Hair, grit and large dust
A metal mesh at the intake. It does not clog, and you never buy another one.
Smoke, pollen and fine dust
Dense synthetic media for the mid-range particles the first stage is too coarse to notice.
Whatever is still left
A high-voltage field charges it and drives it onto collector plates. The plates rinse under a tap.
Clean air out
Three stages. Nothing you ever have to buy again.

The finest particles
H13 is the HEPA grade hospitals build cleanrooms around — made for the sizes that slip past everything else.
Gases, VOCs and odours
Activated carbon for what a filter cannot trap: formaldehyde off new furniture, fresh paint, last night’s cooking.
Clean air out
Four stages. The highest capture grade we can fit.
Where we are
Everything here describes the system and the technology inside it. Airflow, coverage, noise, dimensions and certification are being validated on the prototype now — we will publish those figures when they are measured, not before.
Reserve a unit and you will get the full specification first.
