Resistance to oral moisture and humidity

Continuous use of breathing mouthpieces demands neutral materials that do not leach substances or change elasticity when exposed to saliva or temperature shifts in inhaled air. The medical-grade silicone we use at Verdalia withstands regular warm-water washing without losing flexibility or turning stiff over time.

Machining the flow chamber

The internal valve is turned from 304 stainless steel, a material free from surface porosity where impurities could settle. This allows a quick rinse under the tap after every outdoor workout.

• Burr control: hand-polished finish to prevent sharp edges in the airways.
• Proven safety: neutral components that do not shed particles during repeated suction.

Test bench verification

Before sealing items in their protective packaging, we verify that the airflow mechanism has no unwanted play that could alter the user-selected resistance.
