High-Efficiency Particulate Air (HEPA) and Ultra-Low Penetration Air (ULPA) filters are widely used in various industries, especially in environments that require high levels of cleanliness, such as operating rooms, pharmaceutical manufacturing areas, and semiconductor fabrication plants. This article provides an in-depth analysis of HEPA and ULPA filter testing methods and related standards to help readers better understand and apply these filters.

In light of these considerations, a 0.1 μm particle counter is generally sufficient for most industrial applications. While it may not detect the smallest particles required for precise MPPS measurement in membrane filters, the alternative procedure outlined in ISO 29463 ensures that accurate and reliable filtration efficiency can still be determined. The SC-FT-1406DU, with its high efficiency range, further supports these testing needs, balancing the need for practical solutions with the technical limitations of available particle detection technology.

In the realm of air filtration, the efficiency and longevity of filters are paramount. One innovative method to enhance these aspects is ultrasonic aerosol agglomeration. This technique leverages high-frequency sound waves to manipulate particle deposition, subsequently affecting the pressure drop across air filters. This article delves into the mechanics of ultrasonic aerosol agglomeration, its benefits, and its implications for air filter performance.

HVAC (Heating, Ventilation, and Air Conditioning) air filters play a critical role in modern buildings, ensuring indoor air quality and protecting the efficient operation of HVAC systems. This article examines the key test parameters for HVAC air filters, the relevant international standards, and detailed test methods to help industry professionals and technicians better understand and select the appropriate filters.

In today's world, with increasing concerns about air quality and its impact on health, the need for effective air filtration systems has become paramount. ISO 16890 stands out as a crucial standard in this regard, providing a framework for evaluating the performance of air filters. Let's delve into

ISO 11155-1:2019 is an internationally recognized standard that specifies test methods for automotive air conditioning filters, also known as cabin air filters. This standard plays a critical role in ensuring the quality and performance of these filters, which are essential for maintainISO 11155-1:2019 is an internationally recognized standard that specifies test methods for automotive air conditioning filters, also known as cabin air filters. This standard plays a critical role in ensuring the quality and performance of these filters, which are essential for maintaining air quality in vehicles. This article provides an in-depth interpretation of ISO 11155-1:2019, explaining its key components and implications for the evaluation of automotive air conditioning filters.

FKC-III Microbial Air Sampler is a porous inhalation type dust bacteria sampler, which adopts the principle of isotonic sampling, sampling is direct, and the wind speed of the sampling port is basically the same as the wind speed in the cleanroom, which can reflect the microbial concentration in the cleanroom more accurately.

The need for clean air and water has never been more apparent. During the New Crown epidemic, indoor air quality became a top concern, especially as schools, offices and businesses reopened. Increased consumer awareness drove demand for better indoor air filtration systems. As a result, more people are installing air purifiers in their homes, while many are returning to reopened schools and offices with more modern HVAC systems.
