How many types of clean rooms are there?
A: The most common type cleanrooms are modular cleanrooms, stick-built cleanrooms (or standard), and softwall cleanrooms.
There are 9 classes of cleanrooms in ISO but only ISO Class 5 to ISO Class 8 for 0.5 µm and 5.0 µm are applicable in pharmaceuticals.
The total number of installed/in-use bio/pharmaceutical cleanrooms (in the ISO 5-9 range) is estimated at more than 8,000 worldwide.
Cleanrooms are classified according to the number and size of particles permitted per volume of air. Large numbers like "class 100" or "class 1000" refer to FED_STD-209E, and denote the number of particles of size 0.5 µm or larger permitted per cubic foot of air.
The FDA describes a cleanroom as an isolated environment, strictly controlled with respect to: Airborne particles of viable and non-viable nature, Temperature, Humidity, Air pressure, Air flow, Air motion, and Lighting. There should be a monitoring system for your clean room.
This ISO standard includes these clean room classes : ISO 1, ISO 2, ISO 3, ISO 4, ISO 5, ISO 6, ISO 7, ISO 8 and ISO 9. ISO 1 is the “cleanest” class and ISO 9 is the “dirtiest” class. Even if it's classified as the “dirtiest” class, the ISO 9 clean room environment is cleaner than a regular room.
However, it is generally accepted in the pharmaceutical industry that there are two types of sampling methods for cleaning validation: direct and indirect.
A cleanroom is a controlled environment where pollutants like dust, airborne microbes, and aerosol particles are filtered out in order to provide the cleanest area possible. Most cleanrooms are used for manufacturing products such as electronics, pharmaceutical products, and medical equipment.

Cleanrooms have evolved into two major types and they are differentiated by their method of ventilation. These are turbulently ventilated and unidirectional flow cleanrooms. Turbulently ventilated cleanrooms are also known as 'nonunidirectional'.
What are the types of cleanliness?
We can divide cleanliness into various types such as cleaning clothes, cleaning streets, clean surroundings, clean homes and personal cleanliness. We should make cleanliness our habit because cleaning of our body is important for good physical and mental health.
Most cleanrooms are classified as laminar since all cleanrooms have some form of airflow control. Laminar refers to unidirectional airflow, meaning that air makes a single pass through a room. A common version is where the air enters through the ceiling and exits through outlets in the floor.
A cleanroom is an area free of impurities, where contamination, air velocity, pressure, temperature, and humidity are controlled under rigid specifications. Imagine if the medication we ingest and the electronic components we use were produced in rooms populated with chemical vapors, dust, and airborne particulates.
A cleanroom or clean room is an engineered space, which maintains a very low concentration of airborne particulates. It is well isolated, well-controlled from contamination, and actively cleansed.
As ISO Class 5 cleanrooms are at the more critical end of the class spectrum, they require a greater level of filtration to achieve the level of cleanliness. Ultra Low Penetration Air (ULPA) Filtration is 99.9995% efficient at 0.12 micron and should be considered when looking to achieve ISO class 5.
4.6 Clean rooms and clean-air devices should be classified in accordance with ISO 14644 (2–3, 5–7). 4.6. 1 Classification should be clearly differentiated from operational process environmental monitoring. The maximum permitted airborne particle concentration for each grade is given in Table 1.
An ISO 7 clean room (Class 10,000 cleanroom) is a hard-sided wall manufactured facility that utilizes HEPA filtration systems to maintain air cleanliness levels of a maximum of 10,000 particles (≥0.5µm) per cubic foot.
Positive Air Pressure Cleanrooms normally operate in an air pressure range of 0.02 in. to 0.2 in water column (H20). Positive air pressure means the cleanroom or rooms are "pumped up" with more filtered air then the surrounding space outside the cleanroom(s).
ISO Class 4 Cleanroom Design and Build
ISO 4 or Class 10 cleanrooms are an ultra-clean stringently controlled cleanrooms utilized primarily for nanotechnology, semiconductor, and control zones within biotechnology and pharmaceutical applications for filling lines or other critical points.
An ISO 6 clean room (Class 1000 cleanroom) is a soft- or hard-sided wall manufactured structure that utilizes HEPA filtration systems to maintain air cleanliness levels of a maximum of 1,000 particles (≥0.5 µm) per cubic meter of inside air.
What is a Class 8 clean room?
ISO Class 8 Cleanroom Particle Count Classifications
An ISO 8 or Fed-Std 209E class 100,000 cleanroom must have 3,520,000 particles per cubic meter or less ≥0.5 µm sized particles, 832,000 particles per cubic meter or less ≥1 µm sized particles, and 29,300 particles per cubic meter or less ≥5 µm sized particles.
- Data type validation;
- Range and constraint validation;
- Code and cross-reference validation;
- Structured validation; and.
- Consistency validation.
- Rinse (first time)
- Apply detergent.
- Rinse (again)
- Rinse (last time)
The 2 types of Cleanliness are as follows:
1) Physical cleanliness: Actual tidiness includes end of soil and pollutions from the body, garments, food, houses and the external climate. 2) Spiritual cleanliness: It involves cleanliness related to mind, inner peace.
Clean the 'wet areas' first
Bathrooms and kitchens are known as 'wet areas'. These often take the most time to clean. That's why they should be first in the order you clean your house. Once you've done step 1 and 3, dust everything and then get down to work in your bathrooms and kitchen.
The International Standards Organization (ISO) governs these classifications according to particulate cleanliness. In a nutshell, ISO cleanroom classifications let you know how many particles you're allowed to have in the cleanroom.
