3M™ 5925 PARTICULATE FILTERS

3M 5925 particle filters: P2 respiratory protection in a trapezoidal shape

3M 5925 particle filters provide P2 class respiratory protection against solid and non-volatile liquid aerosols.

Their trapezoidal shape ensures a stable fit and excellent comfort on 3M 6000 and 7500 series half masks.

Ideal for sanding, grinding or handling fine dust, they are a natural choice in demanding industrial environments.

Introducing 3M 5925 particle filters

The 3M 5925 particle filter is a P2 class filter, designed to fit 3M 5000 series half masks.

It retains solid and liquid aerosols up to 10 times the occupational exposure limit (OEL). It is the intermediate protection level, between P1 and P3.

Its trapezoidal shape makes fitting easier and ensures a tight contact with the mask body. Less risk of incorrect fitting in the field.

Trapezoidal design and compatibility with 3M 5000 series half masks

The 5925 clips directly onto 3M 5100, 5200 and 5300 half masks. The bayonet fixing system is identical across the 5000 range.

The trapezoidal shape is not just for looks: it reduces side bulk and improves the field of vision. Useful in confined spaces or during precision work.

These filters are used on their own for protection against dust, fumes and mists. They can also be combined with 3M gas filters for combined protection.

Typical areas of application:

• Sanding, grinding, cutting materials
• Painting work (paint mists)
• Handling industrial powders
• Light welding (in addition to a suitable gas filter)

P2 filtration level: what the EN 143 standard guarantees

The EN 143 standard defines three filtration levels for particle filters: P1, P2 and P3. The 3M 5925 filter is certified P2, the intermediate level.

In practice, a P2 filter retains at least 94% of solid and liquid aerosols tested in the laboratory. It covers the great majority of common occupational exposures.

P2 is suited to fine dust, welding fumes, oil mists and other particles whose concentration remains moderate. As soon as exposure exceeds limit values or the particles are highly toxic, you move to P3 (efficiency ≥ 99.95%).

Here is how the three levels compare:

EN 143 certification also requires breathing resistance tests. A compliant filter must not make breathing too difficult, even after prolonged use.

At Dagobert Industrie, we only offer filters bearing the CE marking with the notified body number, a guarantee that the product has been tested to this European standard.

Areas of application and risks covered by 3M 5925 filters

3M 5925 filters are rated P2, which means they retain at least 94% of airborne particles. They cover a wide range of solid and non-volatile liquid risks.

These filters are designed for use with 3M 6000 and 7500 series half masks. They also fit other masks compatible with the 3M bayonet connection.

Here are the main areas of application covered:

• Construction and renovation work: concrete, plaster, wood and insulation dust
• Manufacturing industry: metal particles, light welding fumes, grinding dust
• Agriculture: organic dust, spores, animal feed meal
• Pharmaceuticals and chemicals: liquid aerosols, non-toxic oil mists
• Joinery and woodworking: sawdust, sanding dust

On the other hand, P2 filters do not protect against gases or vapours. For these risks, a particle filter must be combined with a suitable gas filter (e.g. 3M type A, B or K filter).

The 3M 5925 filter suits environments where particle concentration stays below 10 times the occupational exposure limit (OEL). Above that, a P3 filter or a powered air respirator is required.

Comparison of 3M particle filters: 5925, 5935 (P3) and market alternatives

The 3M 5925 filter is a P2 class particle filter, designed for 3M 5000 series half masks. It filters at least 94% of solid and non-volatile liquid particles. It is the standard choice for moderate-risk environments.

Its higher equivalent, the 3M 5935, moves up to P3 class with a filtration efficiency of 99.95%. It is aimed at more severe exposures: refractory ceramic fibres, heavy metals, residual asbestos.

Comparison table: filtration class, efficiency and compatibility

The 3M 5925 remains the best balance of protection and breathing resistance for everyday work: sanding, light welding, cutting wood, handling cement.

Note: 3M 5000 series filters are not compatible with masks from other brands. The 3M bayonet is proprietary. Always check compatibility before ordering.

At Dagobert Industrie, we offer both 3M references, the 5925 and the 5935, to cover all the particle risk levels found in workshops or on site.

Technical features and specifications of 3M 5925 filters

3M 5925 filters are P2 class particle filters, designed to fit 3M 6000 and 7500 series half masks. Their trapezoidal shape ensures simple fitting and stable positioning on the mask.

They filter at least 94% of solid and liquid airborne particles, in accordance with EN 143:2000. This efficiency covers common mechanical aerosols: wood, stone and metal dust, mineral fibres and some mists.

The filter contains an electrostatic filter medium that captures fine particles without increasing breathing resistance. Breathing stays easy, even during sustained physical work.

Here are the main technical specifications:

• Filtration class: P2
• Standard: EN 143:2000 + A1:2006
• Minimum efficiency: 94%
• Shape: trapezoidal
• Compatibility: 3M 6000 and 7500 series half masks
• Oil resistance: no (non-oily particles only)

FAQ: 3M 5925 particle filters

1. What are 3M 5925 particle filters used for?

3M 5925 filters protect against solid and liquid aerosols: dust, fumes, mists. They are designed to be fitted to 3M 6000 series half masks.

2. What level of protection do they offer?

These filters are certified FFP2 / P2 class to EN 143. They filter at least 94% of airborne particles. This suits environments with moderate concentrations of dust or fumes.

3. Which masks are they compatible with?

3M 5925 filters fit 3M 6000 series half masks (6100, 6200, 6300) via the bayonet system. They are not compatible with full face masks or half masks from other manufacturers without an adapter.

4. What is the difference between 3M 5925 and 3M 5935?

3M 5935 filters are rated P3 and filter at least 99.95% of particles. 3M 5925 (P2) is enough for most everyday work: sanding, light welding, handling powders. The 5935 is required for highly toxic or radioactive substances.

5. Can they be combined with gas filters?

Yes. 3M 5925 filters combine with 3M 6000 series gas filters (e.g. 6055, 6057) using the screw system provided for this purpose. This combination protects against particles and organic or acid vapours at the same time.

6. When should 3M 5925 filters be replaced?

Replace them as soon as breathing resistance increases noticeably or after any contact with hazardous substances. In the absence of a clear signal, follow the life stated by the manufacturer and the recommendations of your risk assessment.
