In workplaces across New Zealand, controlling exposure to dust, fumes, and airborne contaminants is key to protecting health and meeting compliance standards. Whether welding, sanding, grinding, painting, or cutting concrete, choosing the right type of dust mask or respirator can make a critical difference in safety and comfort.
This article outlines five common types of dust masks and respirators, their intended uses, strengths, and limitations. Understanding the features of each will help workshop supervisors and engineers select the right option for the job.
Fabric Masks
Cloth and surgical masks became widespread in public spaces during the pandemic. While helpful in slowing the spread of viruses, these masks are not classed as respiratory protective equipment (RPE). They are unsuitable for dusty or fume-heavy industrial settings and do not meet recognised safety standards like AS/NZS 1716 or EN 149.
On the other hand, certified respirators are specifically designed to protect the wearer from airborne hazards. These must meet rigorous standards, including New Zealand P1, P2, or P3 classifications. The key difference lies in filtration efficiency and the ability to form a proper seal around the face.
Face coverings are functional in low-risk public scenarios. However, a certified respirator is essential in a workshop or construction environment. A basic cloth mask offers no reliable protection for anyone working with wood dust, concrete dust, metal fumes or chemical vapours.
Disposable Respirator Masks (P1, P2, P3 Class)
Disposable respirators are lightweight and convenient for short-term use. Their performance depends on achieving a tight seal around the wearer's face, which is why a proper fit test is essential. These masks are classified according to their filtration level:
- P1 – Basic protection against non-toxic dusts. Ideal for sweeping, sanding untreated timber, or similar tasks involving low-risk particulates.
- P2 – Medium-level protection against fine dusts, smoke, and airborne biological particles such as mould spores or bacteria. Suitable for general building work, fibreglass handling, and non-toxic welding fumes.
- P3 – High-level filtration for fine particles, including crystalline silica, asbestos, or lead dust. Often required for demolition, stone cutting, or work involving hazardous materials.
Proper fit is vital for effectiveness, and respirators should be replaced if damaged, damp, or difficult to breathe through.
For instance, the Esko Breathe Easy P2 Carbon Filter Valved Mask 12Pk provides P2-rated protection and a carbon layer to reduce exposure to low-level organic vapours. This mask has an AIR8™ exhalation valve for improved comfort and dual straps for a secure fit, making it suitable for regular use in construction, welding fume exposure, or light manufacturing.
Disposable masks like these are beneficial for mobile workers or tasks of short duration. However, they are designed for one-time use and must be discarded after removal. While they offer convenience, using them daily can become costly, and they contribute to environmental waste.
Reusable Half Masks with Non-Replaceable Filters
Reusable masks with fixed filters offer a middle ground between disposables and complete reusable systems. The filter element is integrated into the mask and cannot be changed. Once the filter is used up, the whole unit must be replaced.
These are often rated with combination filters, such as A2/P3, which protect against particulates and organic vapours. They're commonly used in woodworking, construction, painting, and finishing. These masks are particularly valued in joinery, cabinet making, and renovation tasks where dust and solvent fumes are present.
The mask body is typically made from soft elastomeric materials that mould to the face and help form a tight seal. This design supports a consistent, repeatable fit each time it's worn. Fit testing is required, and although the filters are not replaceable, these masks may be used for up to 28 days, depending on the exposure level. Users should dispose of them earlier if breathing becomes difficult or contaminants can be tasted or smelled. They often come with resealable bags for safe storage between uses.
Reusable half masks with non-replaceable filters are more economical over time than disposable masks, especially for users who need daily protection. They also produce less plastic waste and are easier to fit correctly due to their more robust design.
Reusable Half Masks with Replaceable Filters
Reusable half-mask respirators with replaceable filters provide flexibility, extended service life, and cost efficiency. With proper maintenance, these masks can be used for months or even years. The filters, which come in a wide range of types, are changed based on exposure type and duration.
Standard filter options include:
- P2 or P3 particulate filters – For harmful dust, smoke, and fumes.
- A1, A2, or B-type gas and vapour filters – For protection against organic solvents, ammonia, or acid gases.
- Combination filters are used for mixed hazards and are often found in painting, agriculture, and heavy manufacturing.
Pre-filters can protect the main filters from early clogging. This is especially useful in dusty environments such as concrete drilling or stone cutting. A basic maintenance program ensures reliability and involves checking the facepiece, valves, and seals regularly and cleaning after each use.
These masks require users to maintain care logs and follow manufacturer guidelines for hygiene. While heavier and bulkier than disposables, they are an excellent option for workshops where the same staff use respiratory protection daily.
Fit testing is essential, and workers must be clean-shaven around the sealing area for the mask to function effectively. Overall, these masks provide a low lifetime cost per use and considerably reduce environmental waste.
Powered Air-Purifying Respirators (PAPR)
Powered Air-Purifying Respirators, or PAPRs, are advanced systems that use a battery-powered blower to draw air through filters and deliver it to the user's headpiece. These units offer superior protection, particularly in high-dust or fume-heavy environments requiring long wear times.
PAPRs are rated under standards such as EN 12941 and come in TH1, TH2, or TH3 filtration levels, with TH3 offering the highest protection. The positive pressure in the headpiece prevents contaminated air from leaking and ensures consistent airflow to the user.
One significant benefit of PAPRs is that they do not rely on a tight facial seal. This makes them suitable for workers with beards or those wearing glasses. They also help reduce fogging and discomfort by delivering cool, filtered air to the face.

Making the Right Choice for Your Work Environment
Choosing a respirator depends on the specific hazards you face, how frequently it's used, your team's comfort and usability needs, and regulatory or site-specific requirements.
- Occasional low-risk tasks: A P2 disposable mask like the Esko Breathe Easy is practical and accessible.
- Regular mixed exposure in trades: A disposable half mask with non-replaceable filters balances convenience and performance.
- Daily work in dusty or fume-heavy areas: A reusable half mask with interchangeable filters reduces waste and operating costs.
- Extended use or high-risk work: A PAPR system like the Strata DW7000XL or Optrel Swiss Air ensures unmatched comfort and consistent safety.
Beyond comfort, correct respiratory protection prevents occupational diseases such as silicosis, chemical bronchitis, and long-term respiratory decline. Investing in appropriate equipment means fewer sick days, better productivity, and peace of mind.
