FFP2 vs FFP3 Masks: What's the Difference?
FFP2 and FFP3 masks may look similar, but they offer different levels of respiratory protection. Learn the key differences in filtration, fit and typical applications.
FFP2 and FFP3 masks are both filtering facepiece respirators designed to reduce the wearer's exposure to airborne particles. Although they can look very similar, there are important differences in their filtration performance and overall level of protection.
If you're deciding between an FFP2 and an FFP3 respirator, understanding these differences can help you select appropriate respiratory protective equipment for the task.
What Do FFP2 and FFP3 Mean?
FFP stands for Filtering Face Piece. Under the European EN 149 standard, filtering facepiece respirators are divided into different protection classes, including FFP1, FFP2 and FFP3.
FFP2 respirators have a minimum filter efficiency of 94%, while FFP3 respirators have a minimum filter efficiency of 99% under the relevant test conditions. HSE material also lists an Assigned Protection Factor (APF) of 10 for FFP2 and 20 for FFP3.
In simple terms, FFP3 is the higher protection class of the two.
FFP2 vs FFP3 at a Glance
| Feature | FFP2 | FFP3 |
|---|---|---|
| Minimum filter efficiency | ≥94% | ≥99% |
| Assigned Protection Factor | 10 | 20 |
| Maximum total inward leakage | ≤8% | ≤2% |
| Protection class | High | Higher |
| Standard | EN 149 | EN 149 |
These figures show that the difference isn't limited to filtration efficiency. The FFP3 classification also permits considerably less total inward leakage than FFP2.
What Are FFP2 Masks Used For?
FFP2 masks provide a substantial level of particulate filtration and may be suitable for a range of environments where respiratory protection is required.
The correct respirator, however, should always be selected according to the particular hazard and level of exposure rather than simply choosing a mask based on its filtration percentage.

What Are FFP3 Masks Used For?
FFP3 is the higher of the two protection classes, offering at least 99% filter efficiency under the applicable test conditions and an APF of 20.
This makes FFP3 respirators relevant where the risk assessment requires a higher level of respiratory protection. HSE guidance emphasises that respiratory protective equipment should be selected according to the hazard and required level of protection.
Apex Business Supplies offers FFP3 masks in packs of 10, providing a convenient option for workplaces and other users requiring FFP3 respiratory protection.
Is FFP3 Better Than FFP2?
In terms of the protection classification, FFP3 provides a higher level of protection than FFP2. But that doesn't automatically mean FFP3 is the correct choice for every task.
The appropriate respirator depends on factors such as the contaminant, concentration, duration of exposure, workplace conditions and the findings of the relevant risk assessment.
Fit is also critical. A higher-rated respirator cannot provide its intended level of protection if it does not seal correctly to the wearer's face. HSE guidance requires appropriate fit testing for workers using tight-fitting respiratory protective equipment.
Why Mask Fit Matters
Filtration performance is only part of respiratory protection.
Air can bypass the filter if a tight-fitting mask does not form an adequate seal around the face. Facial hair in the sealing area can also interfere with that seal. HSE has specifically highlighted inadequate fit testing and facial hair as issues that can compromise respiratory protection.
For workplace use, employers should therefore consider both the required protection level and correct fit when selecting RPE.
FFP2 or FFP3: Which Should You Choose?
The main distinction is straightforward: FFP2 provides at least 94% filter efficiency, while FFP3 provides at least 99% and a higher assigned protection factor. HSE
FFP2 may be appropriate where the relevant risk assessment determines that its level of protection is adequate. FFP3 should be considered where a higher level of respiratory protection is required.
Always select respiratory protective equipment according to the specific hazard, applicable workplace requirements and manufacturer instructions rather than filtration percentage alone.
