Filter Testers

Advance filtration science with test systems designed for research and development. TSI filter testers help scientists and engineers explore media performance, refine product designs, and build data-driven understanding of filtration mechanisms.

What You Can Study

• Fractional Efficiency: Map efficiency versus particle size to identify most-penetrating particle sizes and quantify margins.
• Penetration and Loading: Track early-life penetration and behavior under controlled loading to observe shifts in performance.
• Pressure Drop and Flow: Measure resistance across flow rates to balance energy impact with filtration targets.
• Environmental Sensitivity: Evaluate how humidity, temperature, or charge-neutralization settings influence outcomes.

Core Capabilities

• Flexible Aerosol Generation: NaCl, DEHS/PAO, and PSL options help match media chemistry and test goals, with stable output across runs.
• Particle Measurement Depth: Photometers for integrated penetration screening and particle counters for size-resolved curves from submicrometer to larger sizes.
• Protocol Control: Define dwell times, flow ramps, and scanning sequences to replicate published methods or design custom procedures.
• Data Fidelity: High signal-to-noise detection and calibration workflows support precise, repeatable results across campaigns.
• Analysis and Export: Generate efficiency curves, uncertainty estimates, and comparative overlays; export clean data for Python, MATLAB, or statistical packages.

Applications Across R&D

• New Media Development: Compare fiber diameters, charge treatments, and multilayer constructions with repeatable, apples-to-apples testing.
• Product Optimization: Tune pleat geometry, seal designs, and frame materials to reach target performance with acceptable pressure drop.
• Benchmarking and Method Validation: Align internal methods with widely referenced standards, including EN 1822 and ISO 29463, using controlled parameters and documented setups.
• Exploratory Studies: Examine charge decay, particle re-entrainment, and loading behavior under custom conditions.

Designed for the Lab

• Modular Platforms: Adapt fixtures for coupons, minipleats, and full-size assemblies.
• Broad Flow Control: Cover low-flow media screening through higher-flow device testing.
• Instrument Connectivity: Integrate with complementary aerosol instruments and environmental sensors for richer context.
