Q - How long does PURE-HEALTH last?
A-The photocatalytic reaction does not consume the catalyst titanium dioxide (TiO2), so there is no need to replace the coating PURE-HEALTH and being tied to it in the production phase has a duration equal to that of its support.
Q - Is titanium dioxide safe?
A - Approved by the FDA, TiO2 is harmless to humans and is widely used every day as a food additive, as well as in paint, toothpaste and for a wide range of other applications. Purehealth™ surfaces are safe to touch and there is no risk of dust being released as TiO2 is nanostructured with the other chemical compounds which make up the surface.
Q: What are the differences between a PURE-HEALTH covering and a tradition one?
A: From an aesthetic point of view, the PURE-HEALTH covering is no different from a normal covering. Although titanium dioxide is currently used for its high refractive index mainly as white a pigment, the production processes of the PURE-HEALTH system and the purity of carbon dioxide used allow supports and covering to be made in a range of colours.
Q: Am I obliged to make a PURE-HEALTH environment or can I limit myself to the floor or walls?
A: It is not mandatory but essential for a complete sanitisation. Recent studies have shown that harmful microorganisms can proliferate both on the floors and on the walls. Create environments complete with walls and floors lined with materials PURE-HEALTH ensures optimal sanitation.
Q: How can I recognize whether a space or vehicle is equipped with the PURE-HEALTH sanitization system?
A: For each realization will be issued by the Next Technology, research organization founded and attended by the Ministry of Education, University and Research (MIUR), a certification of compliance of projects carried out with the requirements of the system.
Q: Can I use any type of light?
A: To activate the photocatalytic process requires the irradiation of the molecules of TiO2 by full-spectrum lamps. The lamps used by the system PURE-HEALTH ensure the activation of the photocatalytic process with no UV emission harmful to humans.
Q - Is it necessary to keep the lights on 24 hours a day?
A - No, even intermittent usage of the lights helps to eliminate bacteria, mold, fungi and viruses. For instance, an independent study (Dong & et al., 2009) on the loss of vitality of E. coli cells during the photocatalytic reaction with TiO2 (titanium dioxide) demonstrated that after 15 minutes of illumination, nearly all cells were surviving, whereas after 20 minutes only 12% of the cells had managed to maintain their vitality. At the end of 30 minutes of illumination, over 86% of cells had lost their vitality. This study showed, moreover, that the total elimination of these cells is achieved after 60 minutes of illumination.
Q: So does the PURE-HEALTH system only work with the light turned on?
A: No, once the full photocatlyst load has been reached, the system uses equal timing to interrupt the production of ROS.
Q: The PURE-HEALTH may be an answer in the case of nosocomial outbreaks?
A: As we know nosocomial outbreaks are a constant and growing health risk to operators and users and not least represent a real economic damage to structures. The PURE-HEALTH, using the photocatalytic properties of TiO2, avoids the proliferation of elements viral and bacterial causes of such outbreaks thanks to the constant reduction exerted by the combination between ros and our lighting system.
Q: Does the PURE-HEALTH system work at temperatures lower than 0°C?
A: Yes, thanks to the attention paid to the needs of the customer. In environments with temperatures below 0°c, traditional fluorescent lamps suffer physiological loss of efficiency, whereas the fluorescent lamps used in installations of the PURE-HEALTH Food Division are designed to guarantee an exceptional light output at low temperatures up to -20°c.
