Air Purifiers

My hubby and I just moved into a condo. We did Everything imaginable to make it allergy free… we think (suspect) the prior owner smoked here- but arent sure. So, we repainted, recarpeted, renovated (brand new kitchen), new pergo hardwood floors (cleaner), you get the point. Even replaced the actual air duct work!

We installed IQ Air filter system-works well- but have to run it on Circulate all the time to keep allergies at bay, Hepa filter in bedroom (which is an old filter that wasnt used much) which we run while sleeping, have two air purifiers plugged in (that heat/clean air).

Im still suffering! I wake up in the night with all kinds of allergies, pain in sinus, etc. Its terrible!! I dont want to take drugs, b/c I was fine before I moved in here.

I have itchy ears, eyes, pain in sinus, yucky stuff in throat, etc. I know we have chlorine in water here and every time i do the dishes, i have burning in my eyes from the vapors, so we put a filter in shower.

What am i missing??!!

We are buying an older home and though we are having the duct work and the central unit cleaned, I wanted to attach a whole house air purifier to it. UV lights-Hepa filters-electrostatic-combinations–my head is spinning! I need someone who really knows this stuff to tell me the truth. Help!!

My air filter was inserted incorrectly and now dirt particles are stuck in the heat pump coils. I only have a 4" space to run a vacuum across the coils. Other than to remove the duct work, how would anyone clean these return coils? Seems very dirty and difficult to access.
