Comparison with other sanitization systems


Chemical disinfectants (CHLORINE, ALKALI, ALKALINE-ALCOHOL-AMINE...) can only selectively kill one or similar types of pathogenic microorganisms

Its processing time is long, in the range of 0.5 - 1 hour due to the low rate of chemical reaction and a very high lethal dosage value.

They involve serious secondary pollution.

Its lethal processing is limited to the surface of objects, making it impossible to apply in large air spaces.


At concentrations above 100ppm and high humidity rates, it is an effective disinfection treatment, especially for RNA viruses.

However, high ozone concentrations can be detrimental to coexist in environments in the presence of people. The sanitization achieved by an ozonation process ceases to be effective when people re-occupy the sanitized environment, contaminating it by transporting pathogens.


The solution of UV irradiation implies the need to circulate air through a central duct, but misses protection from those who may bring contamination.

The production rate of (OH·) radicals is low and they are obtained at a low concentration, so the entire biochemical reaction time is long, in the range of 15 - 360 min.

These technologies are only effective in small spaces.

A large number of chemical reagents such as H2O2, TiO2 or Fe2+ are necessary in the production process of (OH·), which results in high costs and a safety problem due to the generation of toxic degradation intermediates and the deactivation of the material


The capacity of HEPA filters is determined by the air flow that it can filter, but additionally, the time it takes to completely regenerate the air in a closed environment is much longer than it takes to be reinfected.

On the other hand, performance conditions are negatively influenced by maintenance conditions and this is expensive and complex. Used filters are a highly polluting elements, both due to their own composition, and due to the volatile and pathogenic elements that have accumulated during use.
