I need help finding a central air condition unit with a whole home air purifier and a new forced air furnace?

I need help finding a central air condition unit with a whole home air purifier and a new forced air furnace for my home. I have roughly $3500 to spend, that is for the parts. The installation will be free. The central air unit and forced air furnace are more of a necessity than the air purifier. Any help would be great!
