What is Safe change filtration?

Safe change filtration is an industry term used to describe technology where contaminants from the air are filtered while the system is running. Safe change filtration saves time, ensuring the productivity of people and equipment in clean production environments.

This process is a safe, efficient way for end-users to maintain confidence in the cleanliness of their air system. It is a system that makes use of controlled and validated filtration, dedicated equipment, dedicated workspace, trained operators, and regular measurement to ensure air-side critical contamination does not enter your cleanroom. It is the final line of defense in a chain of cleanroom parts that ensures safe product manufacturing. We believe that your manufacturing environment is the core of your business.

HVAC systems are a critical component to many industrial, food processing, and pharmaceutical facilities and at Total Clean Air, we can help reduce the risk of contaminations in your operations by ensuring that you have safe change filtration systems in place. Request more information.

What is HEPA filter testing, Dispersed Oil Particulate (DOP) testing or Filter Integrity Testing?

HEPA filter testing or Dispersed Oil Particulate (DOP) testing or Filter Integrity Testing is the most reliable method of determining whether the HEPA filters in cleanroom equipment has been compromised. Filters that come in must be tested and validated in situ before they can be used to make sure they are safe to operate. HEPA filter testing allows manufacturers to fulfil BS EN ISO14644 Part 3 requirements, validation and maintenance program stipulations and ensure the highest possible level of particulate control within their facilities.

HEPA filter testing is a component of Total Clean Air validation services. We have developed our proprietary methodology to ensure HEPA filters are safe for use and continue to perform as expected. We can demonstrate how you can use Safe Change to increase your safety and cleanliness requirements. Get in touch today.

Why you need to test and validate HEPA FILTERS

HEPA Filter Testing and Validation is one of the most vital safeguards for anybody working in a clean environment, be it pharmaceutical, healthcare or food and beverage industries. In this era of increased environmental concerns regarding germs, bacteria and cross-contamination concerns for total air management systems, safety becomes paramount to ensure all workers are safe from hazardous contaminants which they may encounter during operation.

As we know changing a HEPA filter is a simple process that should be carried out at regular intervals. It is the failures in this process that can put your life, health, and safety at risk. Therefore, it is vital that any filters you change are tested to ensure they pass the necessary integrity test.

Total Clean Air has developed the expertise to test all types of HEPA filters. Total Clean Air can help with both safety assurance level (SAL) testing and integrity testing, as required by product specification or safety standard certification. Our experts can help you ensure your Filters are protecting your workers from airborne contaminants. Contact us today for more information about our services.

Preliminary Checks / Qualification

Before you can begin test and validation work, you need to make sure your equipment is correctly set up. This is when the preliminary checks and qualifications are performed.

Preliminary checks include any checks which need to be performed prior to beginning testing. This could include simple checks such as checking that the filter is correctly oriented in its frame and that there are no obvious signs of damage or alteration.

Total Clean Air´s experienced team performs a wide range of preliminary checks and detailed validation of your HEPA filters and HEPA filter systems at every stage of the production.

Filter Maintenance & Testing

The air in laboratories and other sensitive spaces is often much more contaminated than the outside air. This means that if the filters are not maintained properly, these pollutants can circulate around the building, affecting people’s health. For this reason, anyone managing clean rooms or similar settings must be aware of their air filter’s integrity. Filter Maintenance and Testing ensures air filters are working efficiently, effectively, and safely. Total Clean Air provides a full range of certified services and testing to scrutinise and certify your existing system so you can be certain it is functioning as it should.

Periodic testing for leaks

Testing for leaks is a crucial part of any building maintenance program. The results determine the extent of your filter infrastructure, pinpointing areas of concern to reduce energy use and improve safety. Total Clean Air can test your HEPAs and filters for leaks and holes or any contamination problems. We have tested HEPA filters in a wide range of applications such as, Hospitals, Food Processing Plants, Pharmaceutical Labs, Industrial plants, Warehouses, Pharmaceutical Applications etc. Our testing is done with due consideration to your needs. We will liaise directly with your staff to coordinate testing schedules and ensure that your specifications are correctly implemented.

On-site DOP testing and Validation of HEPA filters

DOP stands for deposition optical particle counter. It is a tool used to measure the filter efficiency and particle size distribution which is a key factor in HEPA filter validation. On-site DOP testing gives you confidence that your HEPA filter is operating at its best performance and protects customers, employees, and patients from airborne hazards. Total Clean Air, the leading provider of onsite DOP testing and validation services for air filters, ventilation systems and clean rooms. Our expert staff are responsive and solution-oriented, providing state-of-the-art technical service to help you maintain compliance with ISO 14644-1.

Separative devices

Separative devices, also known as HEPA filters, are particulate (or “particulate matter”) removal devices that employ a variety of mechanisms to remove particles from the airstream. The efficiency of these removal mechanisms is measured as their ability to capture particles 0.3 micrometers (μm) and larger in diameter. Separative devices are the heart and soul of high-efficiency particulate air (HEPA) filters. Therefore, Total Clean Air uses only the best possible system when testing and validating its HEPA filters.
