## Long description

The Alpinestars AG303F protective mask in universal size is a reusable face covering equipped with a replaceable PM2.5 filter and an integrated exhalation valve. Designed to reduce exposure to particulate matter, the mask combines a contoured shape with adjustable ear loops to provide a secure fit for daily commuting, light outdoor activity and general use. The fabric construction supports repeated wear and filter replacement while the valve helps ease exhalation during extended use.
Advantages
The mask features a replaceable PM2.5 filter that captures fine particles and helps reduce inhalation of airborne dust and pollution. An integrated exhalation valve lowers breathing resistance and helps reduce moisture buildup inside the mask. Universal sizing and adjustable ear loops enable a consistent fit for a wide range of face shapes. Reusable construction and removable filter make the unit economical over multiple uses compared with disposable masks.
Suitable for
Daily commuting and public transport
Light outdoor activities such as walking or cycling
Work environments with non-toxic dust and particulate matter
Short-term use where reusable face coverage is preferred
Key specifications
Replaceable PM2.5 filter for fine particle filtration
Integrated exhalation valve to reduce breathing resistance
Universal size with adjustable ear loops for a secure fit
Reusable fabric construction with removable filter insert
Intended for everyday protection against particulate pollution
How to use
Before first use, insert the PM2.5 filter into the designated pocket and ensure it sits flat. Position the mask over nose and mouth, then secure with the ear loops, adjusting them for a snug but comfortable fit. The exhalation valve should be positioned at the front to allow easier outward airflow. Replace the PM2.5 filter according to usage frequency, manufacturer guidance, or when breathing resistance increases. Wash the fabric body by hand or gentle machine cycle after removing the filter and allow it to dry completely before reinstalling a clean filter.
Usage recommendations
Use the mask for protection against non-hazardous particulate matter and urban pollution; it is not certified for medical use or for protection against gases, vapors, or toxic chemicals. Replace the PM2.5 filter regularly and inspect the valve and fabric for wear. Store the mask in a clean, dry place when not in use and follow local guidance on mask use in public settings.
