3M™ 4251+ Half Mask Reuseable Respirator

Introducing 3M™ 4251+, this is a reusable half-mask respirator that provides lightweight, comfortable and effective protection against particles and vapours. Suitable for a broad range of industrial applications, the innovative comfort features help to ensure that the respirator is worn consistently over long periods.


The 3M™ 4251+ respirator features integrated filters, which then enables the field of view to be undisturbed when being used. An adjustable head cradle helps fit a large variety of head sizes, with additional neck-straps for a more secure fitting. An exhalation valve that helps to direct exhaled breath and moisture downward to avoid fogging up glasses or face shields.

Designed to work well with 3M Eyewear and Hearing Protection products.

How long do the filters last?

As particle filters load up with the contaminant they actually become a better filter. However, they become a harder filter to breathe through. The user will notice breathing becoming too hard and will then need to change the filter.
