Special air filters
Depurex is specialized in the engineering and manufacturing of bespoke air treatment filters.
Our focus is on photocatalytic filtration, a technology in which we have been pioneers since 2011.
Other applications for our filters include filtration for professional 3D printers and filters for industrial fume extractors.
Photocatalytic Filters and Fabrics
Odour and VOC abatement
We have been involved in titanium dioxide-activated photocatalytic filtration since 2011, making us pioneers in this innovative filtration technology for the removal of volatile organic compounds.
Photocatalytic filtration is particularly effective in removing unpleasant odors, as well as in many other applications, including indoor air sanitization and ethylene removal.
3D Printers
filters
Metal and polymer dust abatement
Metal or polymer powder 3D printing (selective laser fusion, powder bed, or direct laser sintering of metals) has high overhead costs, especially for filtration.
With Depurex compatible filters, you get the same high quality at a fraction of the cost.
Filters
for fume extractors
Welding fume abatement
We manufacture a wide range of filters for industrial fume extraction systems, including custom solutions for discontinued models.
Photocatalytic Filtration in the Agri-Food Sector: Extending Shelf Life, Odor Abatement, and Sanitization
Photocatalytic filtration represents an advanced air purification technology based on the use of light-activated titanium dioxide (TiO₂), capable of degrading volatile organic compounds (VOCs), odorous molecules, and contaminants through oxidative reactions that transform undesirable substances into harmless products. Originally developed for industrial applications, this solution is finding increasingly significant use in the agricultural and agri-food sectors—specifically in the post-harvest preservation of fruit and vegetable products through ethylene abatement, in the management of odor emissions from livestock farms, composting facilities, and production plants, as well as in improving the hygienic-sanitary quality of process air.
Limitations of activated carbon in VOC treatment: saturation, channeling, and the photocatalytic alternative
Traditional activated carbon filters present three structural criticalities in VOC treatment: channeling (preferential flows that bypass part of the filter bed), progressive saturation of the adsorbent material, and the risk of desorption of pollutants. Titanium dioxide photocatalytic technology, and in particular Depurex hybrid filters, overcomes these limits through a continuous molecular decomposition mechanism, guaranteeing stable performance over time, lower maintenance costs, and documented antimicrobial sanitizing capacity.
