We have recently lowered pricing on most of our UV-C in-duct air purifier units.  Actually, quite drastically on the Airtronics one tube unit.  We have done this because we want to compete with the cheap competitors units out there that are made in China, and other places where there is no real quality control.  Our quality will still remain the same - great - with no compromise.  Spring is coming and we have just the unit you might need to help with your allergies and asthma that will flare up when you go outside. Check us out at [1] www.centralstatescleanair.com.  Uncompromising quality at an unbeatable price!  That’s what you will get with CaluTech products.
