Ozone removal filter series Part 15. - Catalytic poison
Aside from humidity introduced in Part 14 which can detrimentally affect filter's performance, there are also other compounds which can have the same effect.
The last ones to introduce are mist and catalytic poisons such as the following: sulfur, nitrogen, phosphorus, halogenated compounds.
Mist and catalytic poisons block the pores of the manganese dioxide catalyst meaning that the filter cannot function properly in removing ozone due to contact area decrease. This leads to lower ozone removal filter efficiency.
It is important during the design stage to check if any such compounds are present in the air inflow. If so, appropriate measures need to be taken to remove those such as installing a prefilter.
Other substances that can decrease filter's performance are:
