[1] www.Centralstatescleanair.com is our website where we sell UV-C air purification systems by CaluTech.  These are great for relief from allergies, asthma, and other breathing disorders caused by airborne pathogens.  CaluTech is a leading manufacturer of UV-C air purifiers, in-duct systems as well as stand alone ones.  Most of our products carry an unheard of 10 year warranty.  We have been carrying the CaluTech line since 2004 and can readily testify that they work, as our family had allergy problems ourselves and found CaluTech to affordably remedy the situation.
