The air in your home, made visible.
A monitor and a purifier in one. The screen on the front shows you what's in the room, in plain English. The filter inside takes care of it. No app, no account, no cloud. Hand-built in Wisconsin by Joey Rasmussen.
One email when the list opens. Nothing else.
Got it. We'll write when the list opens.
A monitor and a purifier in one.
Made to last ten years, not three.

Three small scenes.
Wildfire smoke is heavy today
You wake up to a sky the wrong color. The AQI app on your phone says 180. You close every window in the house. For the rest of the day, you don't know what the air inside the room is doing — only what the app says about outside. Linden tells you. Then the fan picks up and the number comes back down. You watch it happen on the screen.
Dinner on a gas stove
You sear something on the burner. The cooking-gases number climbs. You crack a window. Linden shows the curve flatten over the next twenty minutes.
A normal Sunday
You walk past Linden on the way to the kitchen. The screen says the air is clean. You don't think about it again for a week.
A purifier that doesn't tell you what it found is a fan in a plastic box.
Most air purifiers ask you to trust them. You push a button and hope it's working. Most air monitors give you a number and leave you to deal with it. Linden does both — sees what's in the room and does something about it — in a single piece you'd want on your nightstand.
A small Wisconsin operation.
Linden is one person at a workbench and the small list of people he's asked to help. We're not racing to scale. We're trying to ship one good thing, learn from it, and ship a slightly better one after that.
Run C is twenty-five numbered units, sold once, then closed. The next run is different.
Get on the list.
One email when Run C opens.
We don't share your address. We don't run campaigns. When the first 25 units are available, you'll get one email.
Got it. We'll write when the list opens.
