Air Filter Functionality: Efficiency vs. Arrestance

Efficiency vs. Arrestance

Commercial air filters remove particulates and gaseous materials from your airstream providing a safer environment for both your workers and machinery. The terms “efficiency” and “arrestance” are used to describe an individual air filter’s functionality.

What is Air Filter Efficiency?

For example, air filter Efficiency measures how well your filter removes microscopic particles such as dust, pollen, mold, bacteria, dust mites and smoke from your airstream.

The Main Differences Between EN779 and ISO 16890

ISO 16890

The main differences between EN 779 and ISO 16890 standards lie in their approach to methods of air filter testing and classification. This change has occurred when the International Standards Organization (ISO) issued it as an effort to improve air quality in light of new studies, regulations, and increasingly high particulate matter (PM) pollution. The focus of the new standard is on fine dust and it is very detailed in its comprehensive test procedures and classification methods.

Temperature Inversions and Air Quality

Temperature Inversions and Air Quality

If you own a home or business in or near a valley, you need to be aware of temperature inversions and how they affect your air quality. Also called thermal inversions, temperature inversions are also more prevalent when and where the nights are longer and cooler. Awareness of temperature inversions will help any home or business choose the best air filter for maximum health and comfort.
