Filters in Air Handling Units & Recommended Final Pressure Drop acc.to EN 13053
In trying to improve indoor air quality (IAQ), air handling units (AHUs) with advanced filters are very important. These systems are crucial for maintaining the purity of air in residential, commercial, and industrial spaces. This article explores the recommended filtration stages and practices for air handling units to achieve the best air quality and save…

Filter Bypass in AHUs and Filter Cabinets and How to Prevent It
Air Handling Units (AHUs) and filter cabinets are essential components of modern Heating, Ventilation, and Air Conditioning (HVAC) systems. They ensure that the air circulating within buildings is clean, fresh, and comfortable for occupants. However, one common issue that can compromise the efficiency of these systems is filter bypass. Below is what bypass costs you,…

Filter Face Velocity and Its Impact on Performance
Face velocity is the air speed through the face of the filter, and it decides more about how a filter behaves than most datasheets admit. Push it up and the pressure drop rises, capture of the finest particles falls, and the media pack takes mechanical strain. Push it down and you need more filtration area…

The Role of Air Filters in LEED-Certified Buildings
The world is becoming increasingly more conscious of its impact on the environment, and as a result, the importance of sustainable building practices has come to the forefront. One of the most well-known certification systems for green buildings is the Leadership in Energy and Environmental Design (LEED) program. Developed by the U.S. Green Building Council…

How to Properly Install an Air Filter in Your AHU
Most filter installation faults come down to two things. Either the element is not seated properly against its frame, or someone has handled the pleat pack with their hands. Both cost efficiency immediately and neither shows up on a datasheet. This post is the installation sequence for a filter in an air handling unit, and…

Optimizing HVAC Systems and AHUs: A Guide to Filter Selection
Eurovent 4/23 gives two ways to pick an ISO 16890 filter class for a building. You either start from the outdoor air quality at the site and work forward, or you start from the supply air quality you want indoors and work backward. The two routes do not always land on the same filter. This…
