How long does a BASE CAMP® Filter last?

The life expectancy of the BASE CAMP Filter depends on many variables, such as particulate exposure density, particulate exposure duration, and user breathing rate. With that said, below are our general guidelines, as the user will have the final call to give your exposure.

20-30+ hours – For high dust exposure (e.g., heavy pollution, grain bins, off-roading, construction/demolition)

30-40+ hours – For moderate dust exposure

50-60+ hours – For allergens, light pollutants, odors, etc.

The filter’s life is also affected by electrostatic adsorption technology.

⚠️Important Notes

Sweat: If the filter gets wet from sweat, its electrostatic properties are significantly reduced, shortening its lifespan.
Electrostatic Particles: The adsorption power decreases over time. We recommend replacing the filter within 30 days of first use, even if it hasn’t reached the full usage time.

Friendly Reminder

The activated carbon filter is replaceable, while the mask shell and valves are washable and reusable. For your safety, please check and secure the valves before wearing the mask to prevent accidental detachment.

When removing and cleaning the mask shell and valves, ensure careful handling and inspection to avoid losing or damaging any parts.
