Let me preface this question: Our old A/C system (air handler is 17 years old)has numerous leaks and is full of mold and other nasty things growing inside. The contractor that I believe will do the best job for me, is planning on replacing the old system (including the duct work) with a 3 ton Carrier comfort series matched with a VS air handler.
The quote I have for the work includes one price with the Infinity Air Purifier and one without. Now my wife does have allergies, but they are not that severe. We are on a very tight budget, so the question is: If we are replacing everything, including the duct work, is it really worth the extra $$$ to have the air purifier installed? How much of a pain is it to install later if we were to wait 6 months and see how her allergies were then? What are your thoughts about this air purifier: nice but not necessary? Or absolutely necessary in a hot and humid climate?
