The closed loop,
renewed.
Replacement silicone tips for the Mark I. Soft enough to wear, firm enough to hold the seal.
- Medical-grade silicone, moulded in one piece
- Asymmetric pair, tuned to inflow and outflow
- Personal to each user — replace every two months
Why two pumps need two shapes.
The Mark I uses a closed-loop system — one nostril takes the rinse in, the other suctions it out. The inflow side carries more pressure than the outflow side, so the Seals are moulded asymmetrically to hold the right tension at each.
You'll feel the difference. The pair fits as a pair.
One per person.
Seals are the only part of the Mark I that touch your skin. Each user in a household needs their own pair — never shared, even between rinses.
Replace every two months, or sooner if you notice any change in the silicone. A spare pair lives in the bottom of every Carriage.
