RGFPHIC-QR9 Replacement Cell for Guardian Air QR+ 9" in-Duct Air Purification

You could order a whole system for what this bulb costs. I had my system installed by a heating and plumbing company at a premium price. It died at about 1 1/2 years. Guardian would not deal with me directly. I had to work through the heating and plumbing company. Turned out the bulb was not the problem, the system was failed. The heating and plumbing company sent this in about a month ago. I'm still waiting for the warranty replacement. If I were doing this again, I would go with a different company and install the system myself.

won't buy again no one gives a sh>>>> my bulb lasted 9 months they are warranty for 2 years no one gauertines it, never again
