The Truth on How a Dynamic Air Cleaner Really Works

By Edited Nov 13, 2013 0 0

Are you mystified at how a dynamic air filter works? Most companies simply say that their products are good, but never bother explaining exactly what made them so.

In this article, we will go through the details and learn how good a dynamic air filter is by learning about its process.

The first process you have to know is impingement. This is when your filter traps dust. The dust should strike the filter media and become attached to it (not pass through it). This method may be a passive way of cleaning but it definitely works.

The next process is polarization. The effect of this procedure is basically the same with ionization. They create a charge on the contaminants to attract them towards the filter fibers.

The sole difference between polarization and ionization is that the latter will produce ozone as a by-product. The polarization process used in a dynamic air filter produces no harmful ozone and is therefore more environment-friendly.

It is a known fact that an electrical charge influences any object within its vicinity. In the case of a dynamic air cleaner, a static charge of electricity is built on a screen. This results to both the dust particles and the filter taking on an electrostatic charge. This charge is also called 'polarized charge".

Both the filter and dust particles act like tiny magnets which attract each other. The magnetic force they create causes the dust (or pollen, smoke etc.) to stick to the cleaner like magnets.

The third process on how a dynamic air filter works is by agglomeration. This term is actually used to describe how the polarized tiny dust particles stick together.

The particles which were previously too tiny for the filter impingement to capture will stick together and form a large-enough bulk of particles that will be caught on its pass through the filter the second time around. Talk about merciless cleaning.

The dynamic air cleaner surely knows how to do its job well. Now, the fourth process is called adsorption. Yes, it is not a typographical error. It's adsorption not absorption.

This is the process where the collected elements (like dust, gases, odor, smoke, etc.) bond with charcoal. It is different from absorption in this sense: Imagine when you place a sponge in a juice puddle, the juice would be absorbed, wouldn't it? And when you squeeze the sponge, the same juice would come back out, right?

Now, in the process called adsorption, the juice which was absorbed by the sponge would bond with it and wouldn't escape again. Cool, you say? This is exactly why a dynamic air filter works truly well.
