Low filtration 2 mm filters

The FiltriNext 2 mm low filtration filters are three-dimensional polyester filters metallised with nickel and treated with a titanium dioxide sol which if used in combination with UVA LEDs with a wavelength of 365 nm or UVC with a wavelength of 260 nm, activate a photocatalysis process capable of killing bacteria and oxidizing contaminating species.

The low filtration 2 mm FiltriNext filters have a long life, thanks to their three-dimensional structure capable of blocking above all solid particulate matter and bacteria, without clogging. They can be easily regenerated by washing (up to 10 times – also in the dishwasher)

Applications

FiltriNext filters may be used:

in existing heating, air conditioning and ventilation systems, replacing or supplementing traditional HEPA filters
in domestic refrigerators or refrigerated counters in shops and supermarkets to improve safety and food preservation
in purifiers for specifically designed indoor environments
in wardrobes, shoe racks and other furniture
in special car purifiers

Electron microscope analysis and EDS spectra

A scanning electron microscope examination combined with EDS microanalysis, conducted by the Politecnico di Milano, shows the presence of titanium dioxide on the treated filters (the gold peaks are due to the investigation technique)
