Effectiveness of photocatalytic filtration against viruses and coronaviruses

Photocatalytic filtration is not only intended for the reduction of volatile organic compounds and odors but is remarkably effective in the abatement of bacteria and viruses (especially in conjunction with a light source in the UVC range).

Fotocatalisi e Sicurezza Ambientale:
Nuove Frontiere per la Qualità dell'Aria Indoor

The pandemic and growing awareness of future health challenges have shone a spotlight on the quality of the air we breathe every day.

We often associate photocatalysis only with the reduction of odors and VOCs, but its potential goes much further: in synergy with UVC lighting, it represents a formidable weapon against viruses and bacteria.

To delve deeper into the scientific mechanisms and benefits of this technology, we recommend the technical "...analysis by Eng. Gian Luca Guerrini in his article 'PHOTOCATALYSIS AND VIRUSES' (credits at the bottom).

What is photocatalysis? How can it be utilized for sanitization purposes? Is it effective against viruses? We take stock of the current situation, updated for the pandemic context caused by the spread of the SARS-CoV-2 virus. A brief discussion on how surfaces and construction products can be functionalized to achieve effective results in improving our environmental conditions.

Maximum effectiveness in air purification with only one filter element

We fully endorse Eng. Guerrini’s analysis: it is precisely upon these scientific pillars that we have designed DEPUREX filtration systems.

Our innovation lies in moving beyond the traditional two-stage system (activated carbon + photocatalytic filter): DEPUREX integrates both functions into a single filter medium. Thanks to a highly efficient activated carbon media treated with titanium dioxide (TiO2), the Depurex photocatalytic filters offer maximum removal capacity in a single, simplified solution.
How the Depurex Hybrid Photocatalytic Filter Works

One issue that rightly concerns manufacturers of air handling units—and that often prevents the use of advanced filtration systems—is pressure drop. After all, the higher the filtration rating, the more “dense” the filter media is.

DEPUREX filters feature an extremely low pressure drop, enabling the creation of high-performance air treatment systems that maximize purification while minimizing the impact on the HVAC installation.

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. This article analyzes the scientific principles of heterogeneous photocatalysis, the primary operational impacts for agricultural and dairy enterprises, and the regulatory and jurisprudential framework regarding olfactory emissions, highlighting how photocatalysis can serve as a sustainable, integrable, and strategic tool for environmental innovation within agri-food supply chains.

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.
