The Total Cost of Ownership of Air Filters
The purchase price of an air filter is usually the smallest number in its lifetime cost. Energy consumption driven by pressure drop dominates, and labour and disposal follow. This post breaks the total cost of ownership into its five parts, pressure drop, energy, filter price, labour and disposal, and shows why the cheapest filter on…

How Often Should You Replace Your Air Filters
Air filters play a crucial role in maintaining the quality of indoor air, ensuring the health and comfort of occupants in a building, and supporting the efficiency of air handling units (AHUs) and industrial applications. An air filter’s primary function is to trap and remove contaminants, such as dust, pollen, and other particulates, from the…

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…

The MERV Rating System: What You Need to Know
MERV runs from 1 to 16 and is the North American way of rating a general ventilation filter. Each band corresponds to a particle size range the filter is expected to hold back, from coarse dust at the bottom of the scale to bacteria carriers and smoke at the top. This post covers what each…

Unveiling the Science Behind Particulate Air Filters: Exploring the Five Core Filtration Mechanisms
A particulate air filter does not work one way. It works five ways at once: straining, interception, diffusion, inertial impaction and electrostatic attraction. Which mechanism dominates depends on particle size and air velocity, and that is exactly why every filter has a worst-performing particle size rather than one flat efficiency figure. This post covers each…
