Mask Bacterial Filtration Efficiency Tester Product Overview
The KP-1000 Mask Bacterial Filtration Efficiency Tester is designed around the complete BFE testing process. It enables laboratories to establish a controlled biological aerosol challenge, expose the test specimen, perform comparative sampling, and retain the main operating data for subsequent evaluation.
The Mask Bacterial Filtration Efficiency Tester uses two six-stage Andersen cascade impactors to collect viable aerosol particles according to aerodynamic size. Its dual-route structure supports comparison between the control aerosol and the residual aerosol collected after passing through the medical face mask material.
Integrated Aerosol Generation
Adjustable spray flow and peristaltic-pump flow support controlled preparation of the biological aerosol challenge.
Dual Sampling Routes
Two coordinated sampling routes operate at a nominal flow of 28.3 L/min for control and downstream collection.
Negative-Pressure Operation
Negative-pressure ventilation, HEPA filtration, pressure monitoring, touchscreen control, and data storage are integrated into the system.

Applicable Standards and Test Method Alignment
ASTM F2101
ASTM F2101 describes a quantitative method for evaluating bacterial filtration efficiency by comparing the bacterial challenge concentration with the residual concentration collected after the aerosol passes through the specimen.
The KP-1000 Mask Bacterial Filtration Efficiency Tester is configured around this comparative aerosol-sampling principle and a nominal 28.3 L/min sampling flow.
ASTM F2100
ASTM F2100 is a performance specification for medical face masks. BFE is one of several performance characteristics. Differential pressure, particulate filtration, synthetic blood penetration, and flammability require separate equipment or procedures.
EN 14683
The Mask Bacterial Filtration Efficiency Tester can be considered for the BFE portion of the applicable EN 14683 procedure. The required edition, sampling arrangement, workflow, and acceptance documentation should be reviewed for each project.
YY 0469 and Q/0212 ZRB003-2015
The original technical information references YY 0469-2011 Appendix B for BFE testing and Q/0212 ZRB003-2015 as the equipment execution standard.
KINGPO model KP-1000 is the product model. ZR100 identifies an equipment type in the technical materials and is not a second product model.
Testing Principle and Workflow
The Mask Bacterial Filtration Efficiency Tester uses a controlled biological aerosol challenge and comparative viable-particle collection process.
System Preparation
Check the aerosol chamber, specimen holder, tubing, Andersen samplers, sampling routes, airflow, pressure conditions, and collection plates.
Aerosol Generation
The aerosol generator and peristaltic pump introduce the bacterial suspension under controlled spray-flow and liquid-feed conditions.
Specimen Exposure
Install the mask or material specimen so that the aerosol passes through the required material face or direction.
Dual-Route Sampling
The Mask Bacterial Filtration Efficiency Tester uses two 28.3 L/min routes to coordinate control and downstream aerosol collection.
Six-Stage Collection
Two six-stage Andersen cascade impactors collect viable particles across defined aerodynamic particle-size ranges.
Incubation and Evaluation
Collection plates are incubated, colonies are counted, and BFE is calculated according to the selected laboratory method.
Laboratory-Oriented Features
Dual 28.3 L/min Sampling Routes
Route A and Route B each provide a nominal 28.3 L/min flow for comparative BFE collection in one system.
Two Six-Stage Andersen Impactors
Each impactor separates viable aerosol particles according to aerodynamic size across six collection stages.
Adjustable Aerosol Generation
The Mask Bacterial Filtration Efficiency Tester provides adjustable spray and peristaltic-pump flow for establishing the biological aerosol challenge.
Negative-Pressure Environment
Negative-pressure ventilation and HEPA filtration support controlled aerosol handling within the equipment enclosure.
Industrial Touchscreen Control
A 10.4-inch color touchscreen, embedded controller, USB interface, and internal storage support equipment control and data retention.
Practical Cabinet Construction
The Medical Face Mask BFE Tester uses a stainless-steel interior, coated steel exterior, observation door, lighting, adjustable support frame, and movable casters.
Standard Supply
Typical Applications
Product and Material Control
Medical face mask development, filtration-material inspection, production quality control, process verification, and supplier comparison.
Laboratory and Inspection Use
The Mask Bacterial Filtration Efficiency Tester provides controlled flow, pressure, aerosol, and sampling conditions for validated BFE procedures.
Comparative Filtration Studies
Suitable for universities, research institutes, and comparative evaluation of applicable porous medical filtration materials.
For medical mask manufacturers, the Medical Face Mask BFE Tester supports product development, incoming inspection, process validation, and routine quality control.
This Bacterial Filtration Efficiency Test Equipment may also be considered for certain porous medical materials when the test method, specimen holder, airflow path, and operating conditions are confirmed.
Test Scope and Limitations
BFE Test Scope
The Mask Bacterial Filtration Efficiency Tester evaluates bacterial filtration through the test material under controlled laboratory conditions.
It supports comparative viable-aerosol testing and does not replace the complete microbiological procedure or laboratory quality system.
Separate Test Requirements
- Respirator approval or respiratory protection
- Face fit, facial sealing, or total inward leakage
- Differential pressure or breathing resistance
- Particle or viral filtration efficiency
- Synthetic blood penetration resistance
- Flammability or microbial cleanliness
Compliance & Regulatory Assurance
The KP-1000 Mask Bacterial Filtration Efficiency Tester is designed to support bacterial filtration efficiency testing associated with ASTM F2101, EN 14683, YY 0469 and the equipment execution standard Q/0212 ZRB003-2015. Its controlled biological aerosol generation, dual 28.3 L/min sampling routes, six-stage Andersen cascade impactors, pressure monitoring and negative-pressure enclosure support comparative evaluation of bacterial filtration performance in medical face mask materials. ASTM F2100 should be considered separately as a medical face mask performance specification that includes BFE together with other test requirements.
Final compliance depends on the complete laboratory procedure, including the applicable standard edition, challenge microorganism, bacterial suspension preparation, aerosol particle-size distribution, positive-control count, sampling flow, specimen orientation, incubation conditions, colony-counting method and result calculation. Supporting microbiology equipment, biosafety controls and laboratory validation procedures must also be reviewed according to the intended application.
Flow, pressure and aerosol-generation verification records, factory inspection documents, operation manuals, equipment certificates and available calibration documentation can be confirmed according to project requirements.
