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.

HEPA and ULPA filters are both high-efficiency air filters that are similar in many ways, but there are some key differences that set them apart in terms of capturing airborne particles.

High-efficiency filters are widely used in various industries and applications that require clean air, such as pharmaceutical, electronics, food, and medical fields. However, different types and grades of high-efficiency filters have different initial resistances, which affect their performance and

Filter material: The selection and application of filter bag material is the core technology of bag-type dust collectors, which affects the performance and lifespan of HEPA filters. Different filter materials should be chosen according to the environment, nature, temperature, and technical requireme

Efficiency is an key indicator of air filters, it reflects the air filter's ability to filter contaminants.
MPPS efficiency, counting efficiency, gravimetric efficiency, fractional efficiency, particulate matter efficiency, initial efficiency, minimum efficiency, integral efficiency, local efficiency etc. Add up to a dozen efficiencies, which efficiency should we really be concerned about? What is the significance of each efficiency?

Filters for compressed air are used in a wide range of applications and testing is an important step in ensuring filter performance and effectiveness. Through airflow measurements, particulate capture efficiency tests, oil mist removal efficiency measurements and life assessment, we can fully evaluate the quality and capability of a filter. Through the correct selection and use of compressed air filters, the quality of the process can be improved, the life of the equipment can be extended, maintenance costs can be reduced and more efficient production can be achieved.

As one of the items of clean room inspection, leakage testing of high-efficiency filters has received more and more attention since the implementation of the 2010 version of GMP.
