Dust Masks and Respirators in Kenya: FFP2, FFP3 and Which One Actually Fits the Job

By Hiren Gohel, Specialised Hardwares

Last in this series, after gumboots, rainwear and hi-vis vests — the fourth category we renamed to match how Kenyan buyers actually search for it. Unlike the other three, dust masks aren’t a rainy-season item; the demand is steady year-round on any site with cutting, grinding, demolition, quarrying or welding work. We stock 16 different masks and respirators, and the most common mistake we see is a buyer grabbing whatever’s cheapest on the shelf rather than matching the mask to the actual hazard in front of them.

In short: for general nuisance dust — sweeping, light demolition, basic site cleanup — a lightweight disposable dust mask is enough. For sustained exposure to fine dust, fibres or mists — grinding, sanding, quarry work — step up to an FFP2 moulded respirator, and choose the valved version if the job is hot or the shift is long, since the valve makes breathing out noticeably easier. For the finest and more hazardous particulates, an FFP3-rated respirator is the higher class we stock. Welding needs its own dedicated respirator rated for metal fume, not a generic dust mask. And a 3-ply surgical or KN95 mask is for general hygiene use, not a substitute for an FFP-rated respirator on a dusty site.

Why the mask has to match the hazard, not just be “a mask”

Dust masks and respirators are rated by how much airborne particulate they filter out, and the rating matters more than the price tag. Our JSP-branded FFP2 respirators are Class 2, medium-efficiency masks offering 94% filtration efficiency against fine non-toxic dusts, fibres, fumes and mists — enough for most construction and site-cleanup dust exposure. FFP3, the class above it, is rated for finer and more hazardous particulates and mists, and is the one to specify when the job or a client’s safety policy calls for a higher class of protection. A basic disposable dust mask, by contrast, is built for nuisance dust rather than a measured filtration standard, and shouldn’t be substituted where an FFP2 or FFP3 rating is actually required.

The types we stock, and who each one is actually for

Lightweight and heavy-weight disposable dust masks

Moulded masks with a metal nose clip and a single elastic strap, sold in packets of 50. The lightweight version (blue box) suits general nuisance dust and short-duration tasks; the heavy-weight version (yellow box) holds its shape better through a longer shift. Neither carries an FFP rating — they’re the right call for basic site cleanup and sweeping, not for sustained fine-dust or fume exposure.

Moulded FFP2 respirator, standard and valved

JSP M21: Class 2, 94% filtration efficiency, EN149 FFP2 rated, with ultrasonically welded straps (no metal parts touching the face), an internal foam strip for comfort, and twin elastic straps. Sold per piece in packs of 20. The valved version adds a cool-flow exhalation valve, sold in packs of 10, which noticeably reduces breathing resistance and heat build-up inside the mask — worth the extra cost for anyone wearing it through a full hot shift rather than short intervals.

FFP3 valved respirator

JSP M32: the higher-rated option we stock, built to minimise breathing resistance while maximising dust-carrying capacity against fine dusts, fumes, fibres and aqueous mists, EN149 FFP3 rated, with the same welded-strap and twin-adjustable-strap construction as the FFP2 range. Sold per piece in packs of 5. This is the mask to specify when the job or a client’s safety policy calls for FFP3 by name, not a general upgrade for every site.

Welding respirator

A dedicated moulded respirator (3M-built) designed specifically for welding, soldering and other operations where metal fumes are present, with a cool-flow exhalation valve, face seal, adjustable nose clip and fully adjustable straps, and protective layers that are flame resistant. A general dust or FFP2/FFP3 respirator isn’t built for metal fume or the heat exposure that comes with welding work — this is the one to stock separately for that specific job.

3-ply surgical masks and KN95

Three-ply, three-pleat single-use masks with elasticated ear loops (packs of 50), and fold-flat KN95 masks rated to filter around 95% of airborne particles. These are hygiene-grade masks for general use and reducing the spread of respiratory particles between people, not a substitute for an FFP2 or FFP3 respirator where the hazard is industrial dust, fume or fine particulate exposure.

Choosing between disposable, FFP2 and FFP3

Start from the hazard rather than the price list: nuisance dust and light cleanup gets a basic disposable mask; sustained fine-dust, fibre or mist exposure gets an FFP2; anything the job or a client’s safety policy specifies as needing a higher class, or genuinely hazardous fine particulate and mist exposure, gets an FFP3. Valved versions cost a little more across both FFP2 and FFP3 but are worth it for full-shift wear or hot conditions, since easier exhalation is what actually keeps people wearing the mask correctly instead of pulling it down.

Pack sizes and ordering economics

Disposable dust masks come in packs of 50, priced as a pack. FFP2 respirators are sold per piece in packs of 20 (or 10 for the valved version), and FFP3 in packs of 5 — reflecting the higher cost of the higher-rated filtration media. Buying in the pack size that actually matches your team’s turnover avoids opening multiple part-used packets at once.

Fit, storage and knowing when to replace

A respirator only protects to its rating if it seals properly against the face — facial hair along the seal line, a poorly adjusted nose clip, or a mask reused well past a full shift all reduce real-world protection below the rated filtration percentage, even though the mask itself still looks fine. Store unused masks away from dust, moisture and direct sunlight rather than left loose in a site container, and replace a respirator once it’s visibly dirty, damaged, or the straps have lost their elasticity, rather than judging it purely on how many shifts it’s been through.

Ordering for a site or a workforce

We handle bulk orders across the full range and can scope a request for quote to the actual hazards on your site — dust, fume, welding, or general hygiene — rather than a flat price list. Getting the mask class right at the ordering stage is cheaper than discovering mid-contract that half the site is wearing the wrong grade.

Frequently asked questions

What’s the difference between an FFP2 and FFP3 dust mask?

FFP2 is a medium-efficiency rating (around 94% filtration) suited to general fine dust, fibres, fumes and mists. FFP3 is the higher class we stock, built for finer and more hazardous particulates and mists — specify it when the job or a client’s safety policy calls for it by name.

Do I need a valved respirator or is a standard one enough?

The valve doesn’t change the filtration rating — it reduces breathing resistance and heat build-up when exhaling. It’s worth the extra cost for a full hot shift; for short or occasional use, a standard non-valved respirator is enough.

Can I use a normal dust mask for welding?

No — welding produces metal fume that a general dust or FFP2/FFP3 respirator isn’t rated for. Use a dedicated welding respirator with flame-resistant protective layers instead.

Is a KN95 or surgical mask the same as an FFP2 respirator?

No — KN95 and surgical masks are hygiene-grade masks for general use and reducing the spread of respiratory particles between people. They aren’t a substitute for an FFP2 or FFP3 respirator where the hazard is industrial dust, fume or fine particulate exposure.

How do I know when to replace a dust mask or respirator?

Once it’s visibly dirty or damaged, the straps have lost their elasticity, or it’s been worn well past a full shift — a respirator only protects to its rated filtration if it still seals properly against the face.

Can Specialised Hardwares supply dust masks and respirators in bulk?

Yes — we deliver in Nairobi and countrywide and can scope a request for quote to the actual hazards on your site rather than a flat price list.

What else to check off on site safety

This closes out the four-part series built around the categories we renamed to match how Kenyan buyers actually search: gumboots, rainwear, hi-vis vests, and dust masks here. Between them they cover footwear, staying dry, staying visible, and now respiratory protection — the everyday PPE most Kenyan sites need before anything more specialised.
