Indoor air especially in hospitals can be filled with airborne pathogens, chemical odors, allergens, dust, and even mold and fungi.  HEPA filters are extremely helpful in reducing many of the hospital particle pollutants and malignant microbes but they cannot capture anything smaller than .3 microns or in gaseous form.  The best air purifier for hospitals needs to have the power to destroy airborne pathogens. 

Photocatalytic Oxidation is the proven technology that does destroy malignant microbes.  The best air purifier uses this technology.   We at Zandair^TM understand the importance of purified air in the healthcare environment and have utilized this superior technology in our products. 

 What is photocatalytic oxidation?  Photocatalytic Oxidation is the process combining UVC irradiation (257.3 nm) with a semiconductor substance (catalyst) titanium dioxide (TiO₂) which results in a reaction that changes malignant microbes into harmless water vapors, carbon dioxide and detritus.¹ 

The best air purifier uses the process of photocatalytic oxidation.  One type of air purification unit we carry is the ZAND-AIR PCOC^TM3   which uses the photocatalytic oxidation process. This unit is These units can be installed into new HVACR systems or retrofitted into an existing air system that pulls air through an air conditioning unit (HVACR) then passes through the professionally installed ultraviolet light/ titanium dioxide chambers.  As the malignant microbe filled ambient air circulates through the three  UV light chambers the microbes are “attacked” by free hydroxyl radicals and super-oxide ions, (created by UV light and titanium dioxide) breaking their cellular and molecular structure apart and destroying both the intracellular mass and DNA/HNA chromosomes. Again as mentioned above the result is are harmless water molecules, carbon dioxide and detritus.

Nosocomial outbreaks can be attributed to airborne pathogens and person to person contact but separating their origin is very difficult.  It is best to use all methods of cleaning and sanitation to help eliminate malignant microbes.  Viruses, bacteria, and fungi, all contribute to nosocomial outbreaks,  some from the environment and others from humans.  Proper and regular hand washing, cleaning and sanitizing surfaces, and using the ZAND-AIR PCOC^TM3 the best air purifier which utilizes photocatalytic oxidation will significantly reduce nosocomial outbreaks, save lives, and reduce the overall cost of healthcare.
