Why it works

Flat-fold comfort, FFP3 protection

Folds flat

Trifold panels fold flat for storage and open out to shape around the face.

Cooler to wear

A high-performance exhalation valve vents warm, humid breath to reduce heat and breathing effort.

Reduced fogging

An adjustable nose bar and soft foam padding shape closely to the nose, cutting fogging of glasses.

FFP3 filtration

Rated FFP3 NR D, the highest level of disposable respiratory protection, to EN 149:2001 +A1:2009.

Longer filter life

The Dolomite (D) clogging test rating means filtration stays effective for longer in dusty conditions.

Individually packed

Each mask is sealed in its own hygienic polybag, suited to vending-machine dispensing.

Frequently asked questions

How is the trifold design different from a moulded cup respirator?

It folds flat into a compact three-panel shape for storage and opens out to shape around the face, rather than holding a fixed cup - useful where pocket or toolbox space is tight.

Does the exhalation valve make a difference at FFP3 level?

Yes. FFP3 masks have the tightest filtration and can feel warm to wear, so the valve vents exhaled air to cut breathing resistance and heat build-up over a shift.

Will it fog up my safety glasses?

The adjustable nose bar and soft foam padding let you shape the mask closely around the nose, which reduces air escaping upward and fogging glasses.

What does the Dolomite (D) rating cover?

It shows the filter has passed the Dolomite dust clogging test, so filtration performance holds up for longer in dusty conditions than a filter without the D rating.

Can I wear it for more than one shift?

No. It is an NR-rated single-shift disposable respirator - replace it once it is damaged, contaminated or breathing becomes noticeably harder.

How is it packaged?

Each mask is individually sealed in a hygienic polybag inside a retail box of 10, which also suits vending-machine dispensing on site.

What protection level does FFP3 give?

FFP3 is the highest disposable filtration class, rated for the finer and more hazardous airborne particles that construction, demolition and quarrying work can produce.
