The 3M VFlex 9105, as worn. Note the "bag like" pleated design.

The 3M VFlex is a line of disposable N95 respirators produced by the 3M Company. The VFlex has a unique, "bag-like" pleated design that increases breathability and allows the respirator to stretch more when the wearer is moving their mouth.

In the US, the VFlex models are:

  • 9105 - the normal size VFlex.
  • 9105S - the small size VFlex.
  • 1804 - healthcare version of the VFlex which is cleared by the FDA as a surgical mask.
  • 1804S - small version of the healthcare VFlex.

The 3M VFlex is a line of disposable N95 respirators produced by the 3M Company. The VFlex has a unique, "bag-like" pleated design that increases breathability and allows the respirator to stretch more when the wearer is moving their mouth.

The VFlex is one of the most breathable non-vented disposable N95 respirators. In 3M's internal testing, the VFlex (model 1804) had a pressure drop of \(~ 5 mm\) of \(H_2O/cm^2\) at \(8 L/m\), lower than other tested respirators. In Aaron Collins' home mask testing, he found the VFlex 9105 to have a pressure drop of around \(0.13 in. H_2O\), the lowest pressure drop of any respirator masks he had tested.
