NOX filter is designed to filter polluted air entering domestic or commercial buildings through mechanical
ventilation systems. The compact system uses combined particulate and gas filters to reduce levels of Nitrogen
Dioxide and Particulate Matter to within target limits making the air safer to breathe.
Gas Filters
Gas Filters are of a metal construction and contain a unique carbon / chemical blend designed to remove
pollutant gases. The gas filters offer a maximum life expectancy of 2 years, but this can vary depending on
pollution concentrations being drawn through the filters.
MAINTENANCE:
Air Filter Replacement and Access
The Gas Filters within the NOX Filter have an expected life of two years in typical city environments when
installed after an MVHR system or Air Handling Unit containing pre filtration. Where pre filtration is not
available, the filters are expected to last a minimum of six months prior to a significant reduction in system air
flow.
