Sunnyda ISO 1 clean room is the highest level of a clean room in the world. And how clean is the cleanroom?
“There are no more than 10 particles of 0.1 microns per cubic meter of space. 0.1 micron is equivalent to one-thousandth of the diameter of a hair. In 1963, the United States formulated the first international cleanroom standard, and it has been continuously revised since then. In 1999, ISO unified the cleanliness standards of various countries and issued standards.
ISO 1 clean room is the highest requirement of the standard, and it is very difficult to achieve. ISO 1 clean room dust-free environment needs to be achieved through some instruments and equipment. Each room has been subjected to many levels of physical filtration to filter out particulate pollution, and then through chemical filtration to filter out molecular pollution.
Although it is difficult to achieve, we can provide various materials for ISO 1 clean room, such as special hand-made walls and ceiling panels for clean rooms. Their thicknesses have 50, 75, 100MM and etc. This kind of board also has different types of core insulation materials, such as rock wool, foam, PU, etc., as well as sound insulation and fireproof glass magnesium, silicon and so on.

Sunnyda ISO 1 Clean Room
Sunnyda’s clean materials have met the highest standards, such as cleanroom panels, cleanroom doors, cleanroom windows, which must not only have the highest level of sealing, but also necessary to ensure the safety of materials and not generate pollution sources. In addition, the stainless steel pass boxed used in the cleanroom must also be of a high standard. The pass boxes need to use a dynamic system. After opening, the system will immediately self-purify and filter the microscopic particles that enter the air. dust. Personnel must pass through different ISO clean rooms before entering the ISO 1 cleanroom. The air shower is one of the best purification tools to absorb the dust attached to the human body.
Although ISO 1 cleanroom is already the highest standard of cleanroom, we have been working hard to do better. Our cleanroom materials of the highest standard are widely used in cleanroom workshops in different industries. We continue to adopt different feedbacks and suggestions from customers. Sunnyda is always pursuing innovation and development.
ISO 1 Cleanroom
Different cleanrooms would be classified based on their cleanliness levels. That is why you get some being ISO1 with others being ISO 9. This guide focuses more on ISO 1 cleanroom, how you can achieve it, and what makes it a top choice for certain applications.
What Does it Mean to be an ISO 1 Cleanroom?
Figure 1 Comparison Between Several Cleanroom Classes
ISO 1 cleanrooms are the highest in terms of cleanliness levels. Due to their classification requirements set by ISO, it has made it hard to get one around easily. Such cleanrooms are only a few around the world. Some of the places you can get such a cleanroom to include the European Space Agency and related institutions.
A cleanroom must meet several requirements and standards before it can be certified as an ISO 1 level. One of the most important requirements is that the cleanroom must have 500 to 750 air changes each hour.
The clean room should also be able to filter particles smaller than dust specks. To help you understand the comparison, the cleanroom must filter particles as small as 0.3 microns. The human hair is about 75 microns and you have a hard time picking it up, so you can imagine what 0.3 microns are all about.
So, the ISO 1 cleanroom would be the cleanest cleanroom you can ever get in the market. A lot also goes into making sure that the cleanroom can also maintain this level of cleanliness over time. Thus, it is expected that it would be more restrictive.
How Do Cleanrooms Work?
Cleanrooms are commonly used for many processes that might easily be affected by particles or contaminants. It is why cleanrooms would be common in fields such as medicine, pharmaceutical, research, and more.
Cleanrooms have filters as part of their construction to help remove pollutants, contaminants, and particles from the air coming from the outside. This air can be recirculated or forced out of the room like in ISO 1 cleanroom.
ISO 1 cleanroom generally requires more filtering to ensure that the cleanliness level is maintained. Also, cleanrooms have to regulate other things such as temperature, airflow, pressure, humidity, and more, depending on what you are doing in the cleanroom.
How Often Should You Test ISO 1 Cleanroom Performance?
It mostly depends on what you are testing. If you are testing the air pressure difference, it should be after 12 months. The same applies to the airflow in your cleanroom. As for the particle count, it has to be done every 6 months for ISO 1 to 5 cleanrooms. The others classes can be tested for particle count every 12 months.
Some of the other tests to conduct include filter leakage, airflow visualization, recovery, and more. make sure to comply with ISO standards when doing these tests to ensure the cleanroom can remain within your desired cleanroom class.
Can a Cleanroom Level Affect My Budget?
Figure 2 Inside an ISO 1 Cleanroom
Like any other project, buying a cleanroom has to be based on the budget. One of the things that would affect your budget is the cleanliness level of your cleanroom. An ISO 1 cleanroom will not cost the same as an ISO 9 cleanroom. You may have to spend more to get an ISO 1 cleanroom because of the cleanliness level.
To help in maintaining the high cleanliness levels, there would be the need to use more machines and other design changes. It is why you would have to spend more to achieve an ISO 1 cleanroom and still maintain its cleanliness level.
If you are unsure where to start looking for a cleanroom, talk to Sunnyda for help. The company would also give you a detailed quotation to help you understand why some cleanroom classes would be more expensive than others.
Where can ISO 1 Cleanroom Be Used?
Due to the level of cleanliness, ISO 1 cleanrooms are mostly used in the life science industry and electronics industry. This is where there is the need for ultra-fine particulate processing. Because of their high cleanliness requirements, they are often rare and not all industries need them.
Designs for Prefab ISO 1 Clean Room
What is the Planning Process for Coming Up with an ISO 1 Cleanroom?
A clean room is not something you just wake up one day and buy from a manufacturer. There are several factors that go into the planning, designing, and finally picking the correct cleanroom. Here are a few things to keep in mind when coming up with an ISO 1 cleanroom.
- Start by analyzing your budget. The budget would determine what kind of cleanroom you can get even if you still want an ISO 1 cleanroom. The size is also dependent on how much the client is willing to pay. When you have an estimate of how much you want to spend, it can help you in also determining the manufacturer. Different manufacturers would have different cleanrooms at different prices.
- You still have to consider the intended use of the cleanroom. ISO 1 cleanroom is mostly used for applications that require the highest level of cleanliness. In such a case, the cleanroom would need more components to help keep it as clean as possible. It is why such cleanrooms would be common in the pharmaceutical sector.
- Next is choosing suitable air conditioning and ventilation systems. Based on the various requirements you may have come up with, it is time to consider choosing a reliable ventilation system. Such a system would help in ensuring that the airborne particles are filtered as much as possible. Also, the system has to control the temperature and humidity to keep the cleanroom working within the right range.
- You still have to consider the access options. There is the need for proper locks meant for specific classes of cleanrooms. Like for ISO 1 cleanroom, it needs the right locks that can help minimize the transfer of contaminants from the outside into the cleanroom.
- You also have to consider the right materials for making the walls, ceilings, and floors. These materials should be easy to clean and still remain resistant to the cleaning agents. You could opt for hard wall or softwall, depending on the use of the cleanroom.
- Cleanrooms also need the right furniture. You cannot just pick any furniture and set it up in the cleanroom. The cleanroom furniture would be made of stainless steel in most cases. This includes the gowning benches, storage cabinets, sinks, trolleys, and so much more.
- There will be the need to also ensure your employees are wearing the correct protective clothing. Employees are at risk of being infected if they do not have the right clothing. Also, they are the same people who might introduce contaminants in the cleanroom. As such, look for the recommended ISO 1 cleanroom protective clothing.
- You still have to consider the cleaning and maintenance needs of the cleanroom. Even if it is ISO 1 cleanroom, it might have different cleaning needs, depending on what you will be doing in the cleanroom. Consult a cleanroom manufacturer such as Sunnyda to help understand what would be the possible maintenance and cleaning needs of an ISO 1 cleanroom.
What is Cleanliness Suitability in Relation to ISO 1 Cleanroom?
Figure 3 ISO 1 Cleanroom in the Aerospace Industry
Cleanroom suitability can be described as the emission of contaminants from an operating material into the cleanroom surroundings. As for cleanliness suitability, it is when you have to determine how many machines can work in a cleanroom without necessarily affecting its cleanroom level. For this case, we are talking about ISO 1 cleanroom.
There are two methods that go into determining the cleanliness suitability in a cleanroom. They include the local measuring method and the holistic method.
The local measuring method has been around for a long time and has always been used to determine cleanroom suitability of different materials. This method involves checking the particle concentration in the cleanroom air at different points around the cleanroom. Once the test is done, the results are checked against the ISO standards used to classify the cleanrooms. In case the particle count is too high, then there is the need to address the problem until it is within the recommended range for ISO 1 cleanroom.
There is also the holistic method. This is a good approach to understand the cleanliness suitability of different materials. However, it cannot be used for the classification of cleanrooms. There is no ISO standard established for this kind of method. The method can mostly be compared against absolute accuracy when testing different materials and machines to see their suitability in an ISO 1 cleanroom.
If cleanliness suitability is done correctly, you can end up with benefits such as preventing rejections, reducing costs of replacing machines, ensuring the quality standards are maintain, preserve competitiveness, and so much more.
Hardwall ISO 1 Clean Room
What are the Differences Between Hardwall and Softwall ISO 1 Cleanroom?
ISO 1 cleanrooms will have multiple applications in different industries. What is important is that you pick the correct one. You will have the option of picking either the hard wall cleanroom or the softwall cleanroom.
The biggest difference between these two cleanroom types is the structure. The softwall cleanrooms would have a rigid frame with curtains acting as its walls. As for the hard wall cleanrooms, they would have fixed panels or cleanroom walls.
To decide which would be great for you, look at the various needs of your project. In most cases, the softwall cleanrooms are used in cases where you may have to move the cleanroom more often to different locations. Also, each type has its pros and cons. Understanding them can help pick the correct cleanroom.
These cleanrooms are for those who want to save on space and enjoy a faster setup process. Once you have set up the outer structure, what remains is adding the curtains to form the walls of the clean room.
Such cleanrooms also need fan filter units to keep the air in the cleanroom contaminant-free. They will be set up on top of the softwall cleanroom. Just make sure you are using high-quality curtains to help prevent the walls from sticking outwards or bulging when the fan filter is in action.
You also have to ensure regular cleaning of the foils. They might not be as easy to clean as the rigid cleanroom panels used for hardwall cleanrooms. The cleaning crew has to be more careful due to the flexibility of the soft walls.
These might be the most common options in the market. They are loved for their rigidity and overall durability. You can be sure to have a great time owning such cleanrooms for decades in some cases. They are mostly built for durability; thus, they will be a great choice for most applications.
There are various materials used in making the cleanroom walls. Such would include aluminum, stainless steel, galvanized steel, HPL, and so much more. If the material has to be a sandwich panel, then it would also need the core materials. The common core materials include aluminum honeycomb, rockwool, PU, EPS, and more depending on the manufacturer.
This type of cleanroom is also likely to hold its pressure better than the softwall cleanroom. It is why the most sensitive ISO 1 cleanrooms would be hardwall types.
Well, it is likely to cost more to get an ISO 1 cleanroom. This is thanks to the various components that go into making it functional. Also, it will cost more to own a hardwall cleanroom compared to owning a softwall cleanroom.
What are the Types of Cleaning You Should Consider for ISO 1 Cleanroom?
ISO 1 cleanroom stands out as being one of the cleanest among the other cleanroom classes. This means that you also have to ensure it receives proper cleaning if you have any hopes of maintaining its cleanliness level. Some of the cleaning types you will have to do include;
Single part cleaning
If you are going to clean single parts, you have to consider things such as the type of contamination, the material, the impact of the cleaning fluids, and the surface material sensitivity.
Single parts in clean rooms are often cleaned using the ultrasonic cleaning method. Such types of parts include optics, ceramics, and other materials with porous surfaces. Ultrasonic cleaning is seen as a great option to get deep into those crevices and get as much dirt as possible out.
Mechanical cleaning is still an option. However, such cleaning also needs the support of suction discharge. Other methods include CO2 cleaning, scrubbing, adhesive foils, and more. You could consult with cleanroom cleaning specialists to see which is better for your cleanroom.
Sometimes you may have complex components that also need cleaning. Such complex components will mostly need mechanical cleaning processes. Such components would have bondings. These bindings cannot be cleaned in an ultrasonic device. A good example is when a component is made by combining different materials, this would mean using different treatments just to clean it.
Residues after cleaning can also be a danger to such components. There is the need to make sure the components are dried 100% after cleaning.
Cleaning of machines can be done during assembly and before commissioning. Whoever will be cleaning these machines needs to have a proper understanding of how the machine works and how it should be cleaned. This is because different parts and components might have different needs. At this point, it is best to hire specialists who know how to do it properly. They would also use specialized cleaning agents to ensure the machine would still be working correctly after the whole process is done.
Maintenance cleaning is what you would get in the manufacturer’s cleanroom manual. This type of cleaning is simple and most straightforward. It will help a lot in keeping the ISO 1 cleanroom in good working condition before major overhauls happen twice a year in most cases. Make sure to follow the instructions when it comes to this type of cleaning. The idea is to ensure you can maintain the cleanroom at the ISO 1 level.
Scientists are doing research in ISO 1 Clean Room
Should You Regularly Maintain ISO 1 Cleanroom?
Yes. Clean room maintenance is vital if you want the cleanroom to maintain its cleanliness level. Also, you would want the cleanroom equipment to continue working correctly. Considering the sensitive nature of the research conducted in ISO 1 cleanrooms, there is the need to properly maintain such cleanrooms.
As for the maintenance intervals, it depends on what you use the cleanroom for. In most cases, an interval of six months should be enough for cleanroom ISO 1 to 5. These cleanrooms need high levels of cleanliness, thus the need to ensure they are properly maintenance of the different parts of the cleanroom.
What has to be serviced also depends on your cleanroom. Some might need fan filter modules changed sooner, while others can stretch it out even more. So, consider working based on the manufacturer’s schedule. It would help you maintain your cleanroom better to make it a contaminant-free space for your research or manufacturing processes.
Can ISO 1 Cleanrooms Work as Mobile Cleanrooms?
Yes. So long as the cleanroom can be prepped to offer a high level of cleanliness, then mobile cleanrooms can also be up to ISO 1 levels.
So, why would someone want a mobile cleanroom? Well, the biggest advantage is mobility. If you need to move your cleanroom more often, such an option would be great. It can help you take the cleanroom where it is needed to work on different projects.
Also, flexibility is another benefit of having a mobile cleanroom. It can always be tailored to the application at hand.
Some also find mobile cleanrooms affordable. Well, it also depends on the number of accessories and supplies that go into making the ISO 1 cleanroom operational. In most cases, it would be cheaper and faster to set up compared to when handling the permanent cleanroom types.

What Can be the Sources of Contamination in an ISO 1 Cleanroom?
Cleanrooms can easily get contaminated if the measures meant to help keep it clean are not monitored correctly. Some are natural, that is why you need to clean the cleanroom more often.
There are up to six main sources of contamination in a cleanroom. They include;
- Process gases
- Water and chemicals
- The personnel
- The facility
- Static electric charge
The most common culprit in clean room contamination is the people working in the facility. People can contaminate the cleanroom through skin flakes and oil, spittle, clothing debris, hair, and cosmetics too. It is why those who work in ISO 1 cleanroom need to dress in specific attire to minimize the chances of contaminating the room.
Fluids can still be a major source of contamination. These are the fluids you would use for cleaning the cleanroom or other processes in the cleanroom. Good examples of such contaminants include deionized water, bacteria and other organics, floor finishes, cleaning chemicals, and plasticizers. If you are going to clean the clean room better, make sure to use the recommended fluids to avoid contaminating the room further.
The facilities too themselves can lead to contamination. Let us say there is debris in the air conditioner. This would likely lead to more dirt getting into the cleanroom when you are trying to keep it out. Also, if the incorrect paint and coating are used, you could still have contamination in the cleanroom. Construction materials such as sawdust and sheetrock would also easily contaminate the cleanroom. There is a need for proper cleaning after construction is complete.
How Best Can You Control Contamination in ISO 1 Cleanrooms?
Figure 5 Operations in an ISO 1 Cleanroom
If you are going to keep the clean room clean, there is the need to keep in mind proper contamination control measures. Here are some of them.
Good hygiene is important
It is estimated that up to 80% of the contaminants are from cleanroom personnel. This includes contaminants such as skin flakes, cosmetics, perfume, and hair. Yes, even the use of cologne and perfume can contaminate the cleanroom. As such, the personnel using the cleanroom needs to practice good hygiene if they are going to help maintain the cleanroom in good condition.
Proper wearing of cleanroom garments is vital
Cleanroom employees need the right PPEs to use in the cleanroom. As much as PPEs are important, they should also be worn correctly. This is because if the garments are not worn correctly, it gives the contaminants a chance to drop into the cleanroom. It is why some cleanrooms would have air showers to further clean the employees before getting into the cleanroom. This is a way of ensuring that the contaminants are kept to a minimum as much as possible.
There might be the need on proper training of your staff on how to wear the cleanroom garments better where necessary.
Keep the cleanroom supplies exclusive
Sometimes you may not realize it, but even using a pen that is from outside the cleanroom can lead to contamination. It is why you need to keep the cleanroom supplies exclusive to the cleanroom at all times. It does not have to be the pen alone, it can be the seats, tools, and so much more. Make sure that the staff understands such supplies cannot be used outside the cleanroom.
The Worker is Cleaning ISO 1 Clean Room
Clean the air conditioning system more often
The air conditioning system is vital in the operations of a clean room. It is why it needs to be in proper working condition all the time. As such, it would be great if you can take your time to properly maintain it too.
As part of maintenance, you may have to clean the air ducts to remove as much dust as possible. Change the filters too to ensure that they are working correctly too. Generally, make sure you are following the recommended maintenance schedule by the manufacturer.
The measures mentioned above are just a few, but will apply to ISO 1 cleanroom and many other types. What is important is that you always follow the cleanroom protocols as a way of ensuring the cleanroom can stay clean too. Also, most ISO 1 cleanrooms would have strict cleaning procedures to follow. This is to ensure that you always keep the cleanroom in good condition. So, make sure you religiously follow such measures to keep the contaminants to a minimum too.
ISO 1 cleanrooms are some of the top options to use when working on highly sensitive projects. Because of the cleanliness level required, you may have to spend a lot more to get this type of cleanroom. As such, you need a specialist to advise you if this is the type of cleanroom you need. Talk to Sunnyda today for more advice on such a cleanroom type and a deal too on one if you want to buy such cleanrooms.
