I am new to IAQ.
Options appear to be limited in this market simply because 95% of all air handlers in Arizona are in the attic or on the roof.
What realistic options are available for me to offer to my customers?
At this point I am thinking that installing an air cleaner in the attic, at the air handler, is just a bad idea. I'm not really sure that there are any options for package units on the roof.
I guess Aprilaire makes a grille mount 6" hepa filter. The 2250 is it?
