What is BS EN ISO 16890:2016?

BS EN ISO 16890:2016 is an international standard that defines the testing and classification methods for air filters used in general ventilation systems. It replaces the previously used EN 779 standard, providing a more accurate and reliable way to evaluate the performance of air filters.

Understanding the Testing Methods

The BS EN ISO 16890:2016 standard introduces new testing methods that better reflect real-life operating conditions. The efficiency of air filters is now assessed based on their ability to remove particles of various sizes from the air, taking into account both coarse and fine particles.

The test measures the particle penetration through the air filter at different particle sizes, ranging from 0.3 microns to 10 microns. By evaluating the filter's performance across different particle size ranges, the standard provides a more comprehensive assessment of its effectiveness in removing airborne contaminants.

Air Filter Classification

BS EN ISO 16890:2016 divides air filters into four main groups based on their performance:

PM1 Filters: These filters are highly efficient in capturing particles smaller than 1 micron, including fine or ultrafine particles such as bacteria, viruses, and combustion smoke.

ePM1 Filters: This category includes filters with an even higher filtration efficiency for particles smaller than 1 micron. These filters are especially effective in environments with high pollution levels or strict indoor air quality requirements.

Coarse Filters: Designed to capture larger particles, such as pollen, dust mites, and mold spores, these filters are commonly used in residential and commercial HVAC systems.

ISO Coarse Filters: Similar to Coarse Filters, these filters comply with ISO 16890 standards and provide reliable performance in removing larger particles from the air.

The Benefits of Using BS EN ISO 16890:2016

The adoption of BS EN ISO 16890:2016 brings several advantages to the industry and end-users:

More accurate evaluation: The new classification system provides a more precise understanding of an air filter's efficiency in removing different particle sizes.

Improved indoor air quality: With better filtration performance, air filters meeting this standard can effectively reduce airborne pollutants, allergens, and contaminants, promoting healthier indoor environments.

Energy savings: By selecting air filters that match the specific needs of a ventilation system, energy consumption can be minimized without compromising air quality.

Compliance with regulations: BS EN ISO 16890:2016 sets a benchmark for air filter manufacturers and ensures compliance with international standards.

In conclusion, BS EN ISO 16890:2016 is an important advancement in the assessment and classification of air filters. Its introduction has enhanced the reliability and accuracy of evaluating air filter performance, leading to improved indoor air quality and energy efficiency. By complying with this standard, both manufacturers and end-users can make informed decisions when selecting air filters for general ventilation systems.
