The Radic8 ODEO Filter was developed by our team to combat the build-up of ammonia and other gases that contribute towards unpleasant odors and uncomfortable indoor environments. The filter is comprised of a combination of chemically treated activated carbon, which is capable of adsorbing high concentrations of a large range of gases, and zeolite, for targeted gas adsorption at lower concentrations.
The activated carbon acts as a first layer of adsorption followed by the zeolite polisher to ensure good economic feasibility and deodorization performance are achieved. The filter’s adsorption efficiency was tested at the Danish Technological Institute in Denmark.

The Radic8 ODEO Filter was tested against the following challenge gases:
Ammonia is a common respiratory irritant and associated with airway swelling and discomfort of the eyes, nose, and throat. Ammonia is a significant contributor to poor indoor odors.
Tested at ±30 ppm
Acetaldehyde is widely used as a testing analogue for formaldehyde. Formaldehyde is common VOC and is associated with cardiovascular risks, respiratory complications, asthma, and malodors.
Tested at ±30 ppm
The gas adsorption efficiency and capacity of the Radic8 ODEO Filter were tested against aerosolized ammonia and acetaldehyde according to an adapted ISO 11155-2:2009 standard.
The ODEO Filter was tested in both horizontal and vertical orientations (laying down or standing upright), to determine the extent to which the efficacy changes based on filter positioning in a potential application.
A continuous supply of the challenge gas was introduced on one side of the filter, with the exiting concentration on the opposite side measured for a period of at least 90 minutes.
As a control measure, an equivalent traditional granular activated carbon (GAC) filter was tested against ammonia using the same methodology. This allowed comparison between the adsorption efficacies of each filter type.
The Radic8 ODEO Filter achieved highly efficient reduction results against each of the challenge gases, in both vertical and horizontal orientations. Against ammonia, it also significantly outperformed the control (conventional granular activated carbon) filter:
Comparative results for conventional carbon filter:
The Radic8 ODEO Filter is laboratory proven to reduce ammonia and acetaldehyde continuously by up to 83% and 51% respectively, over a period of 30 minutes.
