Healthcare, research, pharmaceutical, and biotechnology fields will all need cleanroom repair services, testing, and certification at some point. But, what exactly is a cleanroom?

At SEPS, cleanrooms are one of our areas of expertise. For over 18 years, we have provided cleanroom repair service, as well as biosafety cabinet certification, to various types of facilities across Long Island and the Tri-State area. We’re committed to providing a high quality of service within the controlled environment field.

The Cleanroom, In a Nutshell

A cleanroom is mostly used in scientific and manufacturing industries. Essentially, a cleanroom is a strictly controlled environment in which the levels of pollutants like dust, vaporized aerosol particles or airborne organisms are kept at a minimum.

Cleanrooms are used in labs where these small airborne particles can have an adverse effect on the research conducted. They range in size, with some being on the smaller side and other sometimes thousands of square feet. Some facilities have entire floors that are designated cleanrooms.

What’s Inside a Clean Room?

The contents of each cleanroom vary depending on the work being done. In order to enter a cleanroom, the staff has to enter through airlocks, and sometimes have to step through an air shower prior to entering. An air shower is a pressurized chamber stationed at the entrances of cleanrooms.

After dressing in PPE (personal protective equipment), the staff enters the air shower. Using high-pressure air, the air shower removes any contaminants such as dust, pollen or aerosol particles from the staff member. Some cleanrooms even feature air showers that are stationed in between different sections of the same clean room.

The equipment inside varies depending on the industry. However, the equipment within each cleanroom is uniquely engineered with minimal contaminant output. Similarly, any furniture is designed to produce limited particles. Materials that do produce contaminants like fabrics, pencils, and paper that are made from natural materials are often prohibited from use inside of a cleanroom.

The staff employed in a cleanroom has to go through extensive training before being permitted entry. Any personnel must learn the correct protocol regarding contamination control theory. The uniforms designated are created to prevent any particles from the body contaminating the environment.

The History of Cleanrooms

The cleanroom as we know it today was invented by Willis Whitfield, a physicist. Whitfield worked for Sandia National Laboratories, a nuclear research facility in Albuquerque, New Mexico when he created the original plans for the cleanroom in 1960.

Before Whitfield’s clean room, earlier controlled environments experienced frequent issues with uncontrollable airflows introducing pollutants and contaminants. Whitfield’s vision of the cleanroom featured constantly ventilated and filtered air to remove impurities from the work environment. Within a few years of Willis Whitfield’s original plans, his version of the cleanroom generated $50 billion in global revenue.


Cleanroom Testing & Certification

At SEPS we offer thorough cleanroom services, and that includes testing and certification.

Following strict IEST (Institute of Environmental Services and Technology) and ISO (International Organization for Standardization) guidelines, we perform an extensive range of tests in all of our cleanroom certifications and testing methods.



Cleanrooms are a critical part of the function and efficiency of various industries. At SEPS, we can even offer cleanroom test reports on the spot. SEPS can provide analysis and guidance on your facility, whether it’s for health care, research, or manufacturing.
