Its reputation for efficiency in maintaining indoor air quality has gained favor for the Guardian by many governmental agencies. For instance, the U.S. Military has approved it for use in its field hospitals, and the U.S. and International Hospitals have endorsed it as an effective deterrent to infectious disease. It has also been approved by the USDA, FSIS, and the FDA for use in food-processing plants, to reduce and eliminate microbial contamination as foodstuffs are being processed.
Its domestic uses make it completely suitable for either residential or commercial applications, including applications as a furnace in-duct air cleaner or as a furnace cleaner attached to the HVAC unit itself. It is simply the most versatile and effective unit on the market for killing germs and improving the quality of indoor air for occupants, and this is a huge boost to the respiratory health of anyone protected by the Guardian.
