Aria 19 mask can be used as a device for personal protection in two different configurations:

  1. In combination with the Aria Protection Adaptor (APA) and a P3 filter (standard thread connector EN148- 1, RD 40-1/7”). This filter protects against mist, aerosols, particles, fumes and dust. For more info on filter, see the P3 filter technical sheet.
  2. In combination with the Aria Protection Adaptor (APA), the RD40 40-22 mm adaptor (conical connector 22mm – ISO 5356-1) and an HEPA filter (standard connection ISO 5356-1). This kind of filter protects against airborne and liquid-borne microbial pathogens. For more info on filter, see the HEPA filter technical sheet.

MATERIALS: Polycarbonate


APA: 27 g
RD40-22: 18 g

Easy use

  •  APA and RD40 adaptors are easy to assembly on the Aria 19 mask, also when it is weared.
  •  The strap can be quickly adjusted and fits well almost any face shape, allowing a comfortable wearing and removing.
  •  The voice can be heard clearly throughout the Aria 19 mask thus allowing a good communication.
  •  The high-transparency visor allows a perfect vision (wide optical field) with a slight optical distortion in few areas.More info about how to use safely the 2 configurations based on the Aria 19 mask are available on our website (


Limitations for the use

Do not use in areas where the oxygen concentration is lower than 17% in volume nor in the presence of gases and vapours.

Breathing and no fogging behaviour

The patented breathing circulation system of the mask prevents its fogging thanks to the air circulation inside. Potentially contaminated air is breathed in from the user, drawing it in from only one inlet (the filter adaptor APA) through the filter body, and through a one-way only valve. The filter purifies the air according to its certified properties and characteristics. The safe, breathable air then moves onto the visor, pushed onto it from a deflector placed in the topside of the mask: this action prevents fogging. The air is then drawn through one-way valves in the orinasal pocket where the user breaths in. Once the user exhales, the two one-way valves in the specifically designed orinasal pocket, prevent the air’s return in the ocular part of the mask. Should there be a less than perfect seal between the cheekbones, nose and orinasal pocket contour, the air will not be able to be drawn back up due to the one-way valve placed on the filter adaptor (APA). The only way the air will be forced to go, is through the one-way valve of the chin, to the outside of the mask.
