Not all surgical masks meet the same standard, and the difference matters more than most practices realise until an inspector asks about it. Here is what Type IIR actually means and why it is the standard UK dental practices should be using.
What Type IIR means
EN 14683 defines three mask types. Type I offers the lowest bacterial filtration and is intended for low-risk settings. Type II offers higher bacterial filtration efficiency (BFE) but no fluid resistance. Type IIR adds fluid resistance on top of Type II's filtration standard, making it the appropriate choice for any procedure with a risk of blood or fluid splash, which covers most routine dental work.
Why Type II alone is not enough for dental use
Without fluid resistance, a Type II mask can allow splash-back contamination through to the wearer during procedures involving aerosols, drilling, or bleeding. UKHSA guidance and CQC infection control expectations for dental practices generally assume Type IIR as the working standard for clinical procedures, not Type II.
What to check on your current stock
- Confirm packaging explicitly states Type IIR and references EN 14683
- Check for a CE mark, which should be present on genuine compliant stock
- Be cautious of unusually cheap masks with vague or missing certification claims, since some import stock has been found non-compliant despite claiming a Type IIR standard
Frequently Asked Questions
What is the difference between Type II and Type IIR surgical masks?
Type II masks meet a bacterial filtration standard but have no fluid resistance. Type IIR meets the same filtration standard plus fluid resistance, making it suitable for procedures with blood or fluid splash risk.
Do UK dental practices legally have to use Type IIR masks?
There is no single law mandating Type IIR specifically, but CQC infection control expectations and UKHSA guidance for dental aerosol-generating procedures effectively make Type IIR the working standard for clinical safety compliance.
How can I verify a surgical mask is genuinely Type IIR certified?
Check the packaging for an explicit Type IIR designation referencing EN 14683, along with a CE mark, and request certification documentation from your supplier if it is not clearly stated.
Hospitrade supplies EN 14683 Type IIR CE-certified surgical masks in the full size range, with certification available on request. Shop CE-certified masks.
