The Maxi-Gard represents Respicaireís latest advancement in LED UV and PCO air purifying technology, specifically engineered for ductless and mini-split systems. This system uses multi-spectrum UV wavelengths that work together to optimize performance for both air treatment and coil irradiation. The UV wavelengths radiate at evaporative coils, creating conditions where viruses, bacteria, and mold cannot survive or multiply. The technology combines three distinct purification methods in one compact unit. First, the multi-spectrum UV LED platform delivers broad-spectrum ultraviolet disinfecting wavelengths. Second, the system incorporates PCO (Photo-Catalytic Oxidation) VOC filters as an additional technology layer for enhanced air treatment. Third, the PCO processes help produce friendly air cleansers that work continuously to address various indoor air pollutants, including microorganisms, mold spores, and odors. This non-ozonating air treatment system operates using high-quality, small, and lightweight LED platforms. The dual-voltage, auto-sensing ballasts automatically adjust between 120 and 240-volt applications, making installation flexible across different electrical systems. Available in two models to accommodate different sizes of split systems, the Maxi-Gard offers one of the most practical designs for mini-split retrofits with multiple installation options.
