Canadian clinics, dental offices, and laboratories move through surgical masks quickly, so the ASTM level you choose shapes both protection and budget. ASTM F2100 is the standard that grades filtration, fluid resistance, and breathability from Level 1 to Level 3. This guide explains each level, matches them to real clinical settings, and covers bulk buying, storage, and packaging so your next order goes further.
ASTM F2100 Levels Explained
ASTM F2100-19 is the test method Canadian suppliers reference most often, and Health Canada accepts it as a recognized standard for medical face masks alongside EN 14683. The standard measures four properties: bacterial filtration efficiency (BFE), particulate filtration efficiency (PFE), resistance to synthetic blood, and differential pressure (delta P), which reflects breathability. Higher levels deliver stronger filtration and splash resistance with a slightly denser material.
The table below summarizes the minimum requirements for each level.
| Property | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| BFE (bacterial filtration) | ≥ 95% | ≥ 98% | ≥ 98% |
| PFE (0.1 µm particles) | ≥ 95% | ≥ 98% | ≥ 98% |
| Fluid resistance | 80 mmHg | 120 mmHg | 160 mmHg |
| Delta P (breathability) | < 4.0 mm H2O/cm² | < 5.0 mm H2O/cm² | < 5.0 mm H2O/cm² |
Even at Level 3, delta P stays under 5.0, so the higher grades remain wearable for a full shift. EN 14683 Type IIR masks perform close to Level 2, which is one reason ASTM F2100 is the clearer reference for North American buyers.

Which Level Does Your Clinic Need
General practice and family clinics. Reception areas, consultation rooms, and low-aerosol examinations are well covered by Level 1 procedural masks. The lighter material stays comfortable across long shifts, and the per-mask cost is lower.
Dental offices. High-speed handpieces, ultrasonic scalers, and air-water syringes create heavy aerosols, so most Canadian dental teams keep ASTM Level 3 masks for aerosol-generating procedures and use Level 2 for lower-risk work. Provincial dental college guidance generally points the same way.
Surgical and procedure rooms. Any task with a realistic chance of blood or fluid splash, such as minor surgery, wound care, or phlebotomy, calls for Level 3 protection for the sterile team.
Laboratories. Specimen handling rarely involves high fluid pressure, so Level 2 covers most lab work. Complete the setup with nitrile gloves and bouffant caps. The Aurelia Level 2 mask from CliniEco is made in Canada and tested to ASTM F2100.
Bulk Buying Considerations
Most surgical masks ship in boxes of 50, which stays convenient for small teams. Once your practice goes through more than a box or two a week, ordering by the case changes the math: per-mask pricing drops, and you place one purchase order instead of several. CliniEco's bulk clinic pack keeps the same 3-ply construction at a volume-friendly price.

Storage affects how long masks stay serviceable. Keep cases in a cool, dry room away from direct sunlight, and leave masks in original packaging until needed. Note the expiry date printed on each case and rotate stock so older boxes are used first. A ten-box case typically covers several weeks for a five-person clinic.
Individually Wrapped vs Bulk
Individually wrapped masks arrive one per sealed pouch, and each mask stays clean until it is opened. That makes them a natural fit for exam rooms, dental operatories, and anywhere a fresh mask is opened in front of a patient. The individual packaging also shields each mask from dust and humidity during storage.

Bulk-packed masks are faster to grab from a shared station and cost less per unit. Many practices run a hybrid model: individually wrapped surgical masks at patient-facing stations, bulk boxes in staff areas.
Surgical Mask FAQs
What is the difference between Level 1 and Level 3 masks?
Under ASTM F2100, a Level 1 mask filters at least 95% of bacteria and particles and resists 80 mmHg of synthetic blood. A Level 3 mask filters at least 98% and resists 160 mmHg. Level 3 suits aerosol-generating and splash-prone procedures; Level 1 covers low-risk contact and administrative work. For a side-by-side breakdown, see ASTM mask levels explained.
Do dental clinics need ASTM Level 3 masks?
Dental work generates heavy aerosols, and most Canadian offices keep Level 3 masks for high-speed handpiece and ultrasonic procedures, with Level 2 as a baseline elsewhere. Confirm expectations with your provincial dental college's infection control guidance. CliniEco stocks ASTM Level 3 masks in 50-packs for this purpose.
How many masks should a clinic keep in stock?
A practical target is four weeks of normal use. A five-clinician office consuming roughly 50 masks per day would keep about 1,000 masks on hand, or 20 boxes of 50, plus a reserve for seasonal surges.
Are surgical masks regulated in Canada?
Yes. Medical face masks are Class I medical devices under the Food and Drugs Act, and Health Canada requires importers and distributors to hold a Medical Device Establishment Licence. Ask suppliers for ASTM F2100 or EN 14683 test documentation before ordering.
