Filter Testing & Validation Capabilities

Filter testing is a core part of our custom design process. Every filter we engineer is validated for efficiency, airflow, and compliance before it ever leaves the line, giving OEMs proof their design performs where it counts.

What we can measure to prove performance

Specs on paper don’t mean much until they’re tested. As part of our design process, we validate performance where it matters, so you know your filter will deliver in the field.

Fractional Efficiency

See how well your filter captures particles across the full spectrum  of particle sizes, validated to ASHRAE, ISO, EN, and IEST standards, so performance isn’t in question.

Pressure Drop & Resistance

Airflow makes or breaks your design. We test resistance to confirm your filter delivers the right performance without overworking the system.

Dust Loading

Every filter faces buildup. We measure how it holds up over time, proving service life and stability under the same conditions your product will face.

Integrity & Leak Testing

Leaks compromise everything. With smoke, thread, wet, and dry tests, we verify seals and media so you can trust there’s no bypass in the field.

A filter testing process built around your application

Every OEM comes with different requirements. That’s why testing is incorporated into our custom design process, adjusting to the details of your application to validate performance where it matters most.

Why Rensa's filter tests make a difference

Testing isn’t about passing or failing. It’s about confidence. By validating filters against the right standards and adapting when those standards don’t tell the full story, we give OEMs proof their products will hold up where it matters.

Turning surprises into solutions

Unexpected results don’t stop us; they guide us. We analyze the data, adjust the design, and refine until the filter performs the way your equipment and application demands.

Testing that adapts to your application

Not every product fits neatly into a standard test. We flex our methods to replicate your real-world conditions, ensuring results that reflect true performance.

Our testing facilities and methodologies

Our testing facilities combine custom-built chambers, automated rigs, and non-traditional setups, giving OEMs reliable data to validate performance and compliance at scale.

Testing that matches the real world

From oversized chambers to specialized rigs, we design test setups that replicate your operating environment—delivering data you can trust and performance you can prove.

Custom chambers for big builds

Large filters need testing at full scale, not in reduced conditions. Our custom-built chambers, up to 72”x48”x12”, replicate operating environments so results reflect reality. These chambers allow us to measure airflow, resistance, and efficiency under the same pressures your equipment will face, ensuring performance translates directly from lab to field.

Automated rigs for data you can trust

Our semi- and fully automated rigs simulate real operating conditions with precision. Equipped with aerosol generators, particle counters, and photometers, these systems measure filter efficiency, airflow resistance, and dust loading capacity to international standards. Results are captured and stored in integrated databases, giving you traceable, repeatable proof of performance.

Proprietary rigs for precision

To validate HEPA and ULPA filters, we rely on advanced test rigs built for accuracy. These systems generate a uniform aerosol challenge, track particles upstream and downstream, and record pressure drop in real time. The process confirms efficiency and leak integrity, giving OEMs confidence their filters meet cleanroom, healthcare, or nuclear standards.

Solutions for the non-traditional

Not every filter fits neatly into a standard filter test. Our custom rigs are designed for unique needs, from respirator-sized formats to low-flow or small-scale systems. By tailoring conditions to match your product’s environment, we capture meaningful data that off-the-shelf test setups can’t provide—proof your filter works where it matters most.
