It's already in you.
Particles smaller than a virus walk past your lungs, into your blood, and reach your brain in minutes.
A normal morning in a closed room.
When indoor air sits closed for hours, dust, pet dander, smoke and stale odour do not disappear. They keep circulating.
You wake
up heavy.
Dry throat, blocked nose, tight chest, or a head that feels full before the day starts.
Hair and dander
keep moving.
Pet hair settles on bedding and sofas, and allergies feel worse indoors than outside.
Dust comes
back fast.
You clean, but sunlight still shows tiny particles floating around the room.
The room smells
lived-in.
Sweat, cooking, damp fabric or closed room odour sits on sheets, curtains and skin.
The dirtiest room is yours.
Close the door. Trap everything that came in. Add a stove, a candle, two pairs of lungs exhaling. Now sleep in it for eight hours.
Traffic, dust and smoke at street level.
Door shut. Fan on. Sheets warm. Pet hair moving in the light. This is the air your body keeps meeting.
Catches 99.97%
of what you
can't see

Fewer triggers
Pollen, mould and dander float for less time.
Less brain fog
Better-feeling air during calls and screen time.
