Moreover, higher spending on R&D activities is further propelling growth.

U.S. Filter Integrity Test Market size and growth rate, 2024 - 2030

According to a Pharmaceutical Development Association (PDA) article published in 2022, the introduction of a formal integrity test for sterile filters prior to use is a significant step in ensuring the safety and efficacy of pharmaceutical products. This draft emphasizes the necessity of validating the integrity of sterilized filter assemblies prior to application, especially in situations where processing could potentially cause damage or compromise integrity. Immediate online testing following filter usage, utilizing methods such as diffusive flow, water intrusion, bubble point, or pressure hold tests, is mandated.

In cases of smaller batch sizes where online testing may not be viable, an alternative approach is proposed, provided that a formal risk assessment is conducted, and compliance ensured. It is imperative to thoroughly document integrity testing methods, including acceptance criteria, failure investigation protocols, and justified conditions for retesting filter integrity. The results of integrity tests, including failures and subsequent retests, must be accurately recorded in batch records. Regulatory guidelines emphasize the key role of integrity testing in upholding the sterility and integrity of filters employed in the production of sterile pharmaceutical products.

Growing awareness concerning product purity and stability requirements across several industries boosts the growth of the market. Several companies are focusing on sustainability which is expected to drive the market growth in near future. Nestle is among one of the companies focusing on sustainability.

Nestlé's sustainability efforts are in line with a larger industry movement towards guaranteeing product purity and stability by responsibly sourcing materials and improving manufacturing practices.

Higher spending in R&D Activities is boosting the growth of the filter integrity test market. According to an NCBI article published in August 2021, in many industries such as pharmaceuticals, nutraceuticals, and food and beverage processing, large-scale bioprocessing is fundamental. Traditional control methods, which focus on factors like product yields and productivity, are used in about 90% of these processes.

However, as biopharmaceutical and nutraceutical production methods become more advanced, including the use of genetically modified organisms (GMOs) and complex downstream processing, traditional control systems are showing limitations. There's now a growing need for more effective advanced process control as research complexity increases and processes become more digitized. This involves finding better ways to monitor and regulate bioprocesses to improve both the quality and quantity of products. The discussion around industrial automation and different commercial control strategies has become critical in this perspective.

The process involves applying a specified pressure to the filters after they are installed and flushed, then closing the air feed valve. After a defined time interval, the pressure is noted, and the pressure decay (initial pressure minus final pressure) is calculated. This test relies on the diffusional flow allowed at a defined pressure below the bubble point, and the allowable pressure decay is calculated accordingly. It's a quick and cost-effective way to ensure filter integrity without the need for extensive equipment or specialized knowledge.

The manual segment is anticipated to grow at a significant CAGR from 2024 to 2030. The manual bubble point test ensures filters meet manufacturer specifications, providing a reliable method to verify filter integrity, remove particles, and ensure suitability for use, thus enhancing product quality and safety. This test is typically performed before installation into the system but can also be done after installation with proper plumbing. The filter(s) are installed into a housing, fully wet out with the required fluid, and connected to an upstream air source. The downstream line is directed into a vessel containing water where bubbles can be observed. The upstream pressure slowly increases until a steady stream of bubbles is noted in the downstream vessel. This method is a manual way to verify the filter's ability to remove particles and ensure it is undamaged and suitable for use.

Type Insights

The liquid filter integrity test led the market in 2023 and is expected to grow at a CAGR of 5.0% over the forecast period.
