Cleanrooms are critical environments used in industries such as pharmaceuticals, biotechnology, electronics, aerospace, and food processing. These controlled spaces are designed to minimize airborne contaminants like dust, microbes, and chemical vapors. One of the most vital components in maintaining the integrity of a cleanroom is the cleanroom suit — a specialized garment that prevents contamination caused by personnel.
Selecting the right cleanroom suit supplier directly affects the safety, cleanliness, and productivity of your operations. This guide provides a clear understanding of cleanroom environments, the function of cleanroom suits, and how to choose a trustworthy supplier.
Understanding Cleanrooms and Cleanroom suit
What is a Cleanroom?
A cleanroom is a controlled environment designed to reduce airborne particle contamination during the manufacturing or testing of sensitive products. These rooms maintain precise air quality, temperature, and humidity levels.
Cleanrooms are classified according to the number of particles permitted per cubic foot of air. For instance, a Class 100 (ISO 5) cleanroom allows no more than 100 particles per cubic foot. The smaller the class number, the cleaner the environment. Each industry follows specific standards based on product sensitivity.
Common Cleanroom Classes
ISO Class 1: Ultra-clean, used in semiconductor and nanotechnology manufacturing.
ISO Class 5: Typical in pharmaceutical, biotech, and medical device production.
ISO Class 7: Found in aerospace, automotive, and food processing facilities.
What Are Cleanroom Suits?
Cleanroom suits—often called bunny suits or coveralls—act as a barrier between the wearer and the controlled environment. They prevent skin flakes, hair, and fibers from contaminating the workspace.
Key Features:
Fabric: Typically made from polyester or polypropylene to minimize particle shedding.
Design: One-piece suits with elastic cuffs, integrated hoods, and booties for full coverage.
Breathability: Must allow airflow while maintaining contamination control.
Static Control: Antistatic materials prevent static buildup that can attract particles.
Types of Cleanroom Suits
Nonwoven Disposable Suits: Cost-effective for lower-class cleanrooms (ISO 7+).
Reusable Woven Suits: High-quality polyester suits suitable for higher-class cleanrooms.
ESD (Electrostatic Discharge) Suits: Designed for environments with sensitive electronics.
Full-Body Suits: Provide complete protection, including head and feet coverage.

Gaible Reusable PPE
The performance requirements for reusable cleanroom garments are as follows:
(1) Fibers that are not prone to dusting, falling off, or breaking should be used.
(2) A good filtering effect should prevent the spread of dandruff, scalp, etc., outward through the fabric.
(3) Conductive materials with anti-static properties should be utilized, which are not prone to adhering to dust particles.
(4) Materials that are comfortable, breathable, non-stuffy, and easy to move in should be selected.
(5) The material should have durability to withstand sterilization at 121 degrees Celsius and repeated washing.
Qualified cleanroom garments should exhibit five performance characteristics: cleanliness, barrier protection, breathability, anti-static properties, durability, and comfort.
(1) Cleanliness
The fabric of ordinary cleanroom garments is prone to dust and fiber loss, and is prone to problems such as excessive thread ends, tying at joints, and skipping. Excellent cleanroom garments should avoid dust production and shedding as much as possible, using high-quality polyester filament fabric, combined with professional detail design and edge wrapping, thread processing, etc., to reduce dust production and fiber shedding during wearing, washing, and sterilization processes.
(2) Barrier properties
As is well known, humans are the biggest source of pollution in clean areas, and during their activities, they produce a large amount of dandruff, dandruff, and microorganisms.
An excellent cleanroom garments fabric with fine warp and weft, high weaving density, and tightly wrapped style design can effectively block pollutants generated by the human body from entering the clean area.
(3) Anti static performance
Anti static performance is one of the most important performance indicators for cleanroom garments. Embedding conductive wires into the fabric can quickly dissipate the static electricity generated during the friction process of cleanroom garments, without adsorbing suspended particles in the air and contaminating the operating area. The higher the density of conductive wire, the stronger the anti-static performance, but the material cost will also be higher.
(4) Durability
Excellent cleanroom garments should have excellent durability. During our use, cleanroom garments needs to undergo repeated washing and high-temperature sterilization at 121 degrees Celsius, and its cleanliness will gradually decrease. Excellent cleanroom garments should have solid materials, excellent workmanship, lower degradation rate of cleanliness performance, reduced frequency of clothing replacement, extended clothing service life, and reduced company production costs.
(5) Comfort
Excellent cleanroom garments should be soft and skin friendly, with good breathability and ergonomic design. When personnel wear clean clothes to work, they move freely and smoothly, and there is no sense of restraint even when worn for a long time.
Design of Cleanroom garments
The main purpose of cleanroom garments is to prevent particles and microorganisms from being released from the wearer’s body and polluting the environment.
In terms of style design, it is required to avoid dust accumulation, including reducing wrinkles in clothes; Reduce unnecessary accessories (such as pockets and pencil cases), and do not cover the back if there is a pencil case; The style design should not be too loose, which can reduce clothing friction and reduce hair dust; The cuffs should not adsorb or shed pollutants, and static charges should not accumulate.
Considering the comfort of the wearer, the fabric is required to be breathable and able to expel moisture from the human body.
Other design parameters that should be considered include: zipper material, waist rope position and adjustment function, collar form, hat form and adjustment function, etc.

The style of cleanroom garments
Cleanroom garments styles can be divided into three categories: Coverall (without hood, hooded, hooded and socks attached), two-piece suit, and frock.
1. Coverall
2-in-1（coat and pants attached), 3-in-1(hood, coat and pants attached), or 4-in-1(hood, coat, pants and socks attached) coverall is suitable for A/B and C level clean areas in the pharmaceutical industry. Here, we focus on introducing Gaible’s 3-in-1 coverall.
This style is: coat and pants attached, hooded, with a front zipper that allows for free waist retraction. The cuffs are elastic with a pull loop, and the ankle is flat with hidden buttons. It can be paired with cleanroom boots, shoes (socks), high tube shoe covers, protective goggles, masks, gloves, and bags.
This coverall has three innovative designs.
(1) The hood is connected to the sleeves and back with snap fasteners to prevent the clothes from touching the ground too long during changing, which can cause the outer surface of the clothes to come into contact with the ground and reduce the risk of contamination.
(2) The foot opening is designed with a flat swing buckle, which can fix the foot opening and facilitate changing clothes. There are buttons connected to the ankles and calves. When folding clothes, the buttons are fastened and the pants legs are turned outward. On the one hand, it is convenient to grab the outer surface of the pants legs when changing clothes, and on the other hand, it avoids the clothes from touching the ground too long during changing clothes, which can cause the outer surface of the clean clothes to come into contact with the ground, reducing the risk of pollution.
(3) Pull ring
The design of the pull tab is to fix the position of the cuffs and prevent them from jumping up during large movements, resulting in skin exposure and reducing the risk of contamination.
The difference between a 4-in-1 coverall and a 3-in-1 coverall lies in the connection of pantyhose. In the early days, pharmaceutical companies often used 4-in-1 style, believing that it had good dust and bacteria prevention effects. However, it was inconvenient to work, and when bending down, there was a feeling of being pulled on the back, which made employees feel uncomfortable. It is recommended to use 3-in-1 coverall.
2. Two-piece suit
Two-piece suit is suitable for pharmaceutical industry Class C or Class D.
Gaible has a variety of styles of two-piece suit, including pullover style (hooded), zippered (hooded), stand-up collar zippered (not hooded), and lapel collar zippered (not hooded）
3. Choose a frock in the CNC area
The style of Gaible frock is: suit collar, button style, two square pockets, no waist elastic, used for simple protection or visiting.
