Cool, comfortable respiratory protection with the 3M™ Cool Flow™ Comfort Valve

  • 3M™ Cool Flow™ Valve
    • • Opens 37% easier
    • • 36%+ more airflow
    • • Greater comfort

    The Cool Flow™ Comfort Valve opens 37% easier than the original 3M Cool Flow™ Valve. This results in 36%, 56% or 185% additional exhaled air passing through the valve with the 9300+Gen3 series compared to its predecessor the Aura™ 9300+ (results compare FFP3, FFP2, FFP1 products respectively).

    Therefore the Cool Flow™ Comfort Valve helps deliver a more comfortable breathing experience and greater wearer comfort, making the 9300+Gen3 valved respirators ideal for long periods of wear, especially where conditions are hot, humid or physically demanding.

Less filter media required to achieve the same level of protection

  • Filter Fibre
    The better the charge, the greater the field of capture...

    Using a unique manufacturing process, each fibre in the 3M AEM structure is endowed with a very high electrostatic charge. This high level of charge enables each AEM fibre in your 3M filter to attract particles from a wider capture area, efficiently drawing them in and securing them to itself.

  • Comparison of Filter Media
    ...requiring less filter fibres to achieve the same level of protection.

    The strong 3M AEM charge means less fibres are needed to efficiently capture particles. This enables 3M to construct an effective filter with a much more open structure than conventional electret filters, freeing up the passage of air.
