Respirator Half Mask 3M 4279+, ABEK1P3 reusable, combination filter, blue/white

The 3M 4279+ respirator half mask is a reusable half-face solution combining a comfortable fit with multi-hazard respiratory protection. Fitted with an ABEK1P3-rated combination filter, this unit protects against a range of contaminants including organic vapours, inorganic gases, acid gases and particulates. Designed as a single-piece wearable system in blue and white, the mask suits industrial, maintenance and mixed-environment tasks where both gas/vapour and particulate filtration are required.

Advantages

The respirator offers certified combined filtration in one cartridge, reducing the need to change between different filters when facing mixed hazards. Its reusable half-mask format supports repeated use and simple maintenance, and the form-fitting design aims to provide a reliable seal during normal work activities. Constructed to balance protection and wearer comfort, the blue/white finish makes the device easily identifiable in workplace PPE sets.

Suitable for

• Industrial maintenance and repair work with mixed vapour and dust exposure
• Painting, solvent handling and tasks involving organic vapours
• Work involving acid gases or inorganic gaseous contaminants at moderate concentrations
• Environments with both particulate and low-to-moderate gas/vapour hazards

When it may not be suitable

This half-mask is not intended for environments with oxygen deficiency or immediately dangerous to life or health (IDLH) conditions; it provides respiratory protection only within its certified contaminant types and assigned protection factors. It may also be unsuitable for users requiring full-face protection, head/face impact protection, or for exposures exceeding the filter's rated capacity.

Key specifications

• Filter classification: ABEK1P3 combination filtration for organic vapours, inorganic gases, acid gases and particulates

How to use

Fit the half mask to the face following the manufacturer’s fit instructions, ensuring a secure seal around nose and mouth. Install or verify the correct ABEK1P3 combination filter is fitted and inspect the unit for damage before each use. Perform a user seal check every time the respirator is donned. Replace filters as recommended when breathing resistance increases, smell or taste of contaminants is detected, or according to workplace replacement schedules. Clean and store the mask in a dry, contaminant-free location when not in use.

What to consider before purchase

• Confirm the ABEK1P3 filter types match the contaminants present in your work environment
• Ensure half-face protection provides adequate assigned protection factor for your tasks
• Consider fit testing and user comfort for prolonged wear
• Plan for replacement filters and routine maintenance

Usage recommendations

Use the respirator only for the contaminants and concentrations covered by its ABEK1P3 rating; ensure regular inspection, correct filter replacement and user seal checks to maintain protection effectiveness.
