What is Class 100 Clean Room?

A clean room is typically a lab/room with a controlled environment in which pollutants such as dust, aerosol particles, airborne microbes, etc. are extremely low in quantity. Such rooms are necessary for the manufacturing of certain products that can't be risked with even the smallest level of contamination or for scientific research, engineering applications etc.

Clean rooms are divided into various classes and Class 100 is one of the best in terms of quality and efficiency.

  • A class 100 clean room has 100 dust particles of 0.5 microns per cubic foot of air compared to a standard office space that usually has at least 5,00,000 particles per cubic foot of air.
  • The environment inside a class 100 clean room lab can be controlled to a great extent with various factors including humidity, temperature, air quality, pressure, etc.
  • When it comes to data recovery from storage media devices, a class 100 clean room or above is extremely important for successful recovery. This is because hard drives are extremely sensitive to heat and humidity which can affect the recovery process. In addition to that, hard drive manufacturers also strongly recommend a class 100 room for opening any hard drive so as to prevent pollutants such as dust particles from sticking to the magnetic platter of the device that can potentially damage the read/write head upon operation.

How does Stellar Data Recovery make the most of its ISO Certified Class 100 Clean Room Lab?

At Stellar, class 100 clean room allows us to perform all our data recoveries in a safe and secure environment. Whether it's a damaged laptop/desktop/external hard drive, the lab allows our data recovery engineers to beat the odds and recover the lost/deleted files from the device for you in their original condition.

We make it a point to never operate on any type of storage media device outside of the clean room as that's poor practice and only advocated by inexperienced and amateur data recovery firms. In fact, we go to great lengths to ensure that data recoveries are performed within the bounds of our lab only because that's the only way to protect your hardware as well as the data stored on it.

Stellar's Class 100 Clean Room Environment

At every single class 100 clean room lab that Stellar has across the globe, a set of well-defined and stringent rules are followed without exception. These are:

  • Entry and exit only through air showers and airlocks
  • Access limited to only authorized data recovery professionals
  • No entrance allowed without proper cleanroom-wear that includes lab coat, apron, boots, bouffant caps, gloves, hairnets, etc.
  • Advanced biometric control systems
  • Top level data security and protection

The Way Forward

Stellar strictly enforces the use of class 100 clean rooms at all of its recovery centers as that's the only way to achieve a nearly 100% recovery in a safe and secure environment. At the same time, it advises all the people who are looking for a data recovery service to avoid taking service from firms that offer "clean rooms" that are not ISO certified or barely meet the industry standards.


  • Never try to open your hard drive to recover the data on your own
  • Data recovery is a complex and skill-driven process. Only professionals trained in data recovery technologies are capable of getting the desired results
