PHOTOCATALYTIC AIR FILTER

The innovative photocatalytic air filter technology is a purification technique that allows the abatement of pollutants and odors thanks to sunlight (Photocatalytic Filters) or dedicated lamp-induced radiation (Photocatalytic Reactors). Technologically advanced and patented, photocatalytic purification combines high encumbrances abatement performances to low plant management, hence being widely appreciated

FUNCTIONING OF PHOTOCATALYTIC AIR FILTERS

The photocatalytic filter-based treatment is an innovative means combining two technologies: the absorption on adsorbent substrates and the photocatalysis on noble metal catalysts. Pollutant molecules get adsorbed in the filter and are subsequently put in the part of the fabric with a titanium dioxide (TiO₂) layer. On the catalyst’s surface the degradation of pollutant molecules through radical ions happens (chain oxidation), ending with the discharge of non-toxic and inodorous molecules: CO₂ and H₂O.

PHOTOCATALYTIC AIR FILTERING WITH PHOTOCATALYTIC FILTERS

Entirely developed by BMB, our photocatalytic filters are the result of years of study and research for an innovative, cheap and easily manageable method to air purification. These filters exploit solar radiation to activate a noble metal catalyst purifying the polluted air. Precisely for the secure nature of our photocatalytic air filter technology, no accessory utility is required to function (electric energy, compressed air etc.).

PHOTOCATALYTIC AIR FILTERING WITH PHOTOCATALYTIC REACTORS

In order to face increasingly burdensome abatement requests, BMB developed Photocatalytic Reactors. The reactors’ functioning principle is the same as the Photocatalytic Filters’, except for the catalyst activation, made with specific UV lamps set to an ad-hoc length. Modular, completely wired up and equipped with their own power supply panel, the Photocatalytic Reactors are an example of the most recent technological progress in the field of photocatalytic purification.

FAQs about photocatalytic filters

What is a photocatalytic filter?

A photocatalytic filter is an air purification device that uses a photocatalyst, typically titanium dioxide (TiO₂), combined with ultraviolet (UV) light to break down pollutants in the air. When UV light activates the photocatalyst, it generates reactive molecules that can decompose organic compounds, bacteria, viruses, and odors into harmless substances like carbon dioxide and water.

How does a photocatalytic filter work?

The filter works by leveraging a process called photocatalysis. When UV light illuminates the photocatalyst material, it excites electrons, creating electron-hole pairs. These pairs generate reactive oxygen species (ROS) such as hydroxyl radicals and superoxide ions. The ROS then oxidizes and breaks down organic pollutants and microorganisms in the air, effectively neutralizing them.

What are the benefits of using a photocatalytic filter?

Benefits include:

Effective Decontamination: Removes a wide range of pollutants, including volatile organic compounds (VOCs), bacteria, viruses, and odors.
Low Maintenance: The filter doesn’t get clogged like traditional filters, reducing the need for frequent replacements.
Energy Efficiency: Operates effectively with low energy consumption.
No Harmful Byproducts: Converts pollutants into harmless substances without producing secondary pollutants.

Where are photocatalytic filters commonly used?

They are used in:

Residential Air Purifiers: For improving indoor air quality.
Commercial HVAC Systems: In offices, hotels, and shopping centers.
Healthcare Facilities: To reduce airborne contaminants in hospitals and clinics.
Industrial Settings: For controlling emissions and odors in factories.
