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.

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.
