Respirators & Cleanroom Face Masks
Equivalent names: “3M 9001V mask”, “8210 mask”, “cleanroom mask”, “activated carbon mask” — difference: genuine 3M products with CO, all 3 groups from one supplier (particulate respirators – medical – cleanroom), stable carton pricing.
Most common items: 3M 9001V, 9541V, 8210 and white 4-ply.
Delivery: in stock, delivered within 24–48 hours (Ho Chi Minh City, Binh Duong, Dong Nai); lead time for bulk orders is confirmed with the quotation.
Three mask groups for three different needs. Fine particulate respirators (3M N95/KN95): 8210, 8822 (exhalation valve), 9001V, 9332A+ (FFP3), 9501V, 9541/9541V (activated carbon) — for grinding, painting, welding and chemical areas. 4-ply medical masks: white/blue/grey, plus an activated-carbon odour-reducing version — for offices and general assembly. 3-ply cleanroom masks: low-lint nonwoven, latex-free ear loops — for ISO 7–8, SMT and finished-goods packing.
| Group | Model | Filtration standard | Used for | Packing |
|---|---|---|---|---|
| Fine particulate | 3M 8210 | N95 (NIOSH) | Grinding, dry dust | 20 pcs/box |
| Fine particulate, valved | 3M 8822, 9001V, 9501V | FFP2 / KN95 | Dust, heavy work | 10–50/box |
| Particulate + odour | 3M 9541, 9541V | KN95 + activated carbon | Painting, light solvents | 25/box |
| High filtration | 3M 9332A+ | FFP3 | Chemicals, toxic dust | 10/box |
| 4-ply medical | White / blue / grey / carbon | Per supplier test report (if available) | Offices, assembly | 50/box · 40–50 boxes/carton |
| 3-ply cleanroom | Nonwoven | Low lint, latex-free | ISO 7–8 | 50/bag · 2,000/carton |
| KF94 / VC65 | HJ, Neomask | KF94 | Service areas | 50/box |
Selection by area
– Grinding, spray painting, welding → 3M 9541V / 9001V (valved for long shifts).
– Volatile chemicals → 3M 9332A+ or a respirator mask + filter cartridges (PPE-HEAD).
– Assembly lines, cleanrooms → 3-ply cleanroom mask.
– Offices, visitors → 4-ply.
Documents: 3M CO, test report (if available) per lot.
Recurring orders: price held for 6 months, minimum stock of 5 cartons of 4-ply and 10 boxes of 3M.
FAQ
– What is the difference between N95, KN95 and FFP2? — Same filtration level of ~94–95 % for 0.3 µm particles, different standards (US / China / Europe); Japanese/Korean factories usually accept all three.
– Can valved masks be used in cleanrooms? — No; the exhalation valve does not filter, so cleanrooms use unvalved masks.
– How do cleanroom masks differ from 4-ply medical masks? — Lower lint, latex-free loops and no exposed metal in the nose strip, clean packaging.
– How to tell genuine 3M? — Model code embossed on the mask face, seal label on the box, CO supplied; PRIMEAG photographs the labels before delivery.
Three types of masks protect three different things
- Particulate respirators N95, KN95, FFP: protect the wearer from dust particles, fumes and mists. The edges are designed to seal tightly to the face.
- Medical masks: according to the FDA, these are loose-fitting, with no seal around the nose and mouth; they mainly block droplets and splashes — they cannot replace particulate respirators.
- Cleanroom masks: protect the product from particles and droplets from the operator; the main requirements are low lint and clean packaging, not filtration efficiency for the wearer.
N95, KN95, FFP2, FFP3 — comparison by standard
Based on 3M’s comparison and the technical data sheet for the 3M Aura 9300+ series:
| Standard | Minimum filtration efficiency | Maximum inward leakage | Notes |
|---|---|---|---|
| N95 (NIOSH, USA) | ≥ 95 % (NaCl salt test) | — (workplace fit test required) | Test flow rate 85 L/min |
| KN95 (GB2626, China) | ≥ 95 % (NaCl) | 8 % | Test flow rate 85 L/min |
| FFP2 (EN 149, Europe) | ≥ 94 % (NaCl and paraffin oil) | 8 % | Use up to 10 times the occupational exposure limit (OEL) |
| FFP3 (EN 149) | ≥ 99 % (penetration ≤ 1 %) | 2 % | Use up to 50 times the OEL |
Markings on European-standard masks: NR = non-reusable, single shift only; D = passed the dolomite dust clogging test, so breathing stays easy during long work in dusty environments.
Filtering dust does not mean filtering solvent vapour
- FFP/N95 masks protect only against dust and non-volatile liquid particles; they do not protect against gases or vapours.
- 3M describes the activated carbon layer of the 3M 9541/9541V as helping to reduce organic vapour odours at nuisance levels — not as protection against solvent vapours at significant concentrations. Paint mixing, adhesive mixing and high-volume IPA wiping areas need a half-face mask with organic vapour cartridges (PPE-HEAD).
- Do not use in oxygen-deficient atmospheres (below 19.5 %), where contaminants are unknown, or at concentrations immediately dangerous to life or health.
Only a sealed fit works
- Position the straps correctly and press the nose clip around the bridge of the nose with both hands.
- Perform a seal check every time you put it on (per 3M): valved mask — inhale sharply, the mask should collapse slightly toward the face; unvalved — exhale sharply, no air should leak at the edges.
- Beards and long sideburns break the seal — the FDA notes that N95 respirators are not designed for people with facial hair.
- As recommended by 3M, users must be trained and fit tested in accordance with each country’s regulations.
When to replace and how to store
- Discard the mask when it is torn, deformed or dirty, when breathing becomes difficult, or at the end of the shift (NR types).
- Leave the area immediately if you have difficulty breathing or feel dizzy.
- Example for the 3M Aura 9300+ series: store in a clean, dry place at −20 to +25 °C, humidity below 80 %, in the original packaging; 5-year shelf life printed on the box. Check the expiry date before issuing to workers.
Medical masks: reading ASTM F2100 levels correctly
| Level | Bacterial filtration efficiency (BFE) | Synthetic blood resistance |
|---|---|---|
| Level 1 | ≥ 95 % | 80 mmHg |
| Level 2 | ≥ 98 % | 120 mmHg |
| Level 3 | ≥ 98 % | 160 mmHg |
When a factory requires an ASTM level, a test report stating the level achieved by the exact model is needed.
Identifying genuine products
- Genuine N95 respirators are printed with the manufacturer’s name, model number and a NIOSH approval number in the form TC-84A-xxxx. Look it up in NIOSH’s Certified Equipment List (CEL): the model and approval number must match.
- NIOSH warns of signs of counterfeits: unusually low prices, “unlimited stock” during market shortages, and advertising that stresses “authentic”.
