Carbon filters

A carbon filter is made from activated charcoal, which is microporous coal produced by charcoal either by physical or chemical activation. The coal can then be used for various cleaning processes. The shape of the charcoal after activation differs according to the purpose for which it is to be used.

Since activated charcoal is really good at absorbing bad odours in the environments they are placed, it is obvious to use it to clean the air that enters houses and buildings from the outside. 

The life of a carbon filter varies greatly depending on the amount of air and gases it absorbs. It is therefore necessary that you observe any changes in the air quality after a few months.

Production of carbon filters

Our carbon filters are manufactured at our own factory in Denmark. Carbon filters are activated charcoal constructed as either mats or in a sturdy frame containing activated charcoal pieces / cubes. Each cube contains 100% activated charcoal and has a size of 48x48 mm and 676 outlets per unit cell. A typical filter consists of 40-60 cubes - so 676 outlets per cube provides a total of 27-40,000 outlets. This gives the carbon filter an extremely large surface area and high density within the plastic frame.

It is important to keep in mind that a carbon filter is meant to complement an existing granular filter in the ventilation system.

The carbon filter is mounted on after the primary granular filter, as this first filters particles like dust. The carbon filter layer will then absorb any odours that may be in the air.

Sustainability is a high priority

Sustainability has always been something that Danfilter has given high priority to. We are part of the fight to reduce the climate footprint and have therefore taken sustainability to heart. Every day we strive to make our production and everyday life more sustainable.

Our filters are, among other things, made of plastic, the majority of which comes from recycled materials. In addition, all our filters are flammable, so throwing out old filters can be done guilt-free as they will be converted into new energy.
