Cleanroom Certification Services in Columbus OH
Precision Environments has spent more than 35 years designing, building, and certifying controlled environments across the country. We serve Columbus and the surrounding region from our Cincinnati headquarters, and we’re one of the few firms nationwide that handles the full scope of a cleanroom project, from the first planning conversation through construction, certification, and long-term maintenance.
Our cleanroom certification services are backed by A2LA ISO/IEC 17025:2017 accreditation and a performance guarantee we stand behind on every project. If you’re certifying a new build or bringing an existing facility back into compliance, you’ll work with a team that has seen the inside of more than 1,000 controlled environments.
What Cleanroom Certification Actually Means
Cleanroom certification is how a facility proves its controlled environment performs the way it was designed to perform. It’s a formal, documented process that verifies your room meets its specified ISO classification and the regulatory requirements that come with it. This is a distinct but related process from cleanroom performance testing, which evaluates how a room operates on an ongoing basis. Certification is the formal validation that the environment meets its specified classification at a defined point in time.
For industries operating under strict compliance frameworks, certification isn’t optional. Facilities that can’t produce current certification documentation face real consequences: failed inspections, halted production, and regulatory findings that take significant time and resources to resolve. The standards that govern this process define exactly how testing must be conducted, what acceptable results look like, and what documentation needs to accompany the certification. These standards include ISO 14644-1, IEST-RP-CC006-2, and Current Good Manufacturing Practices (cGMP).
Holding current certification tells everyone who needs to know, from FDA inspectors to your own quality team, that your environment is operating at the level it claims to be.
How Precision Environments Approaches Cleanroom Certification
Our certification process begins well before the testing agency arrives. During start-up and commissioning, our team works through proprietary standard operating procedures and detailed inspection reports to confirm the room is running exactly as designed.
At this stage, we document actual capacities and current draws across mechanical, electrical, and control systems. Every component gets checked against the original design specs. We don’t move forward until we’re confident the installation is complete and performing to specification.
From there, third-party certification is conducted per ISO 14644-1 and IEST-RP-CC006-2. The independent nature of that testing is intentional. The certification you receive reflects a verified result from a qualified external agency, supported by our A2LA accreditation and satisfaction guarantee.
Cleanroom Testing: What We Measure and Why It Matters
Cleanroom testing is a structured series of measurements, each one targeting a specific performance parameter of the controlled environment. Together, they build a complete picture of how the room is functioning. Precision Environments conducts all of the following as part of the certification process:
Airborne Particle Counts
The primary measurement for determining ISO classification. Particle counters are used at designated locations throughout the room to confirm the concentration of airborne particles falls within the rated cleanliness level.
HEPA Filter Leak Test (Ambient Air or PSL)
Verifies that HEPA filters are installed correctly, with no defects, leaks, or compromises to the frame, seal, or filter media.
HEPA Airflow Velocity
Confirms that the airflow volume moving through each HEPA filter aligns with the design specifications for the system.
Room Pressurization
Checks that the pressure differential between the cleanroom and adjacent spaces is maintained at the correct level, keeping unfiltered air out of the controlled zone.
Air Exchange Rates
Measures how much air cycles through the space each hour, confirming the ventilation system is meeting the requirements for the room's classification.
Airflow Volume/Velocity Readings
Looks at total airflow supply into the cleanroom or clean zone and verifies that the system is delivering what the design calls for.
Temperature/Relative Humidity
Confirms that temperature and moisture levels are consistent throughout the space and staying within the set points established by the HVAC control system.
Microbial Monitoring
Evaluates viable biological contamination levels in the environment. This test carries particular weight in pharmaceutical, life sciences, and medical device settings where biological risk factors directly into regulatory compliance.
Lighting Level
Measures illumination across the cleanroom to confirm conditions meet both the facility's design specifications and any applicable industry standards.
When every measurement comes in within specification, you have a certified environment that can withstand scrutiny from any auditor or regulatory agency.
Cleanroom Recertification in Columbus
Getting certified is the starting point, not the finish line. Over time, cleanrooms change. Filters age, equipment wears, and operational adjustments can shift environmental performance in ways that aren’t always immediately visible. Annual recertification is how facilities stay ahead of those changes and maintain continuous compliance.
Precision Environments’ recertification program runs through the same core parameters covered during initial certification: airborne particle counts, HEPA airflow velocity, room pressurization, air exchange rates, laminarity, temperature/relative humidity, and lighting level. Results are compared directly to your established baseline to determine whether the environment continues to meet its rated classification.
There is real value in working with a team that has a long history with your facility. We recertify and service labs we originally built more than two decades ago. That kind of familiarity means our team picks up on things a fresh set of eyes walking in for the first time would likely overlook. In regulated environments where documentation history and institutional knowledge carry real compliance weight, that relationship matters.
A2LA Accreditation and ISO/IEC 17025: What It Means for Your Facility
Precision Environments holds A2LA accreditation under Certificate #2573.01 and is ISO/IEC 17025:2017 certified. ISO/IEC 17025 is the international benchmark for testing and calibration laboratory competence, and achieving it requires independent evaluation of our testing methods, equipment calibration practices, and documentation standards.
For your facility, that translates to test data that is traceable, well-documented, and capable of standing up to regulatory review. These aren’t internal quality claims. They’re independently verified.
This carries particular significance for clients in pharmaceutical, medical device, and life sciences sectors. When an FDA inspector or a third-party auditor pulls your certification documentation, the credibility of the organization that produced it makes a difference. A2LA accreditation gives your records the backing they need to hold up when it counts.
Industries We Serve in Columbus
Columbus-area facilities across a wide range of industries rely on Precision Environments for cleanroom certification services. Our work extends well beyond the region, spanning the U.S. and 15 countries internationally, but our Columbus clients get the same depth of expertise and accredited credentials that define every project we take on.
Every one of these sectors comes with its own compliance landscape, and our team brings the industry-specific knowledge to work within it accurately and confidently.
What Makes Precision Environments Different
Testing-only firms show up, collect their measurements, hand over a report, and leave. That’s the standard model for most cleanroom certification providers. Precision Environments operates differently, because in most cases, we designed and built the room we’re certifying.
That background changes what certification looks like in practice. Our team walks into a Precision Environments cleanroom already knowing the mechanical systems, the DDC control logic, the design intent, and the construction specifics. When a test result looks unusual, we’re not starting from scratch trying to understand why. We already know the system, which means we can get to the root of the issue faster and with more accuracy.
For Columbus clients bringing us in to certify a room built by another contractor, we apply that same analytical depth. More than 1,000 controlled environments over 35 years means our team has worked through nearly every configuration and complication the industry produces. We approach every facility, regardless of who built it, with the same level of rigor.
We back every certification we perform with a satisfaction guarantee. Combined with the fact that 80% of our work comes from repeat clients, our track record speaks for itself.

Frequently Asked Questions
How often should a cleanroom be recertified?
For most cleanroom classifications, annual recertification is the accepted standard. Facilities in heavily regulated sectors like pharmaceuticals or medical device manufacturing may need to test more frequently depending on their specific compliance obligations and the sensitivity of their manufacturing processes.
What is the difference between cleanroom certification and cleanroom validation?
Certification verifies that a cleanroom is performing within its rated ISO classification at the time of testing. Validation takes that further, producing documented evidence that the environment consistently delivers results within defined limits for a particular process or regulatory requirement. Precision Environments provides both services.
Does Precision Environments certify cleanrooms it didn't build?
Yes. Our certification and recertification services apply to any controlled environment, regardless of who originally designed or constructed it. Our team brings the same technical standards and accredited testing protocols to every facility we work in.
