The 3M 7500 series protective half mask is a newer and more sophisticated model than the 6000 series.

This model is available in three sizes namely S (7501), M (7502) and L (7503).

A protective mask is used when working with sprays in closed spaces, or where there is greater exposure to vapors from sprays. It is reusable and has replaceable bayonet filters, in our case the A2 series (for aerosols) + P2 (for particles). For this, of course, you need a plastic holder, which you can use to attach the P2 filter to the A2 filter. Filters must be purchased separately, they are not part of the package.

This range of reusable masks features the 3M™ Cool Flow™ Valve, which, thanks to its low breathing resistance, allows warm exhaled air to escape, helping to reduce heat build-up. The mask has a soft seal surface for comfort and a unique head harness with an optional launch strap. This ensures comfortable wear even during long-term use. It has a design with two filters for even weight distribution and minimal restriction of the field of view.

After using the mask with the given filters, do not forget to pack the mask in a transport bag so that the filters do not wear out. If you don't pack it, the filters continue to filter and wear out.

Filters are changed according to wear, P2 filters are changed more often (they are changed after they are sufficiently clogged), A2 filters are changed less often - it depends on the use.

How to choose the right mask size?
Roughly, it can be determined by measuring the distance from the root of the nose to the chin.

• Size S = up to 11.5 cm
• Size M = from 12cm to 13cm
• Size L = over 13cm
