Ok I have a 2400sqft house, 2 stories. Live in AZ so there is a lot of dust and we as a family have problems with allergies and pet hair. I see 2 ways to setup air purifiers in the house, I am asking your opinion on which one is the better setup, money is not an issue just setup.
Have lower end air purifiers running in each room so all they have to do is work in each of the rooms.
Buy 2 high end air purifiers, such as the iqair which states it covers 1250 sqft, one that runs in a general area on the first floor and the second unit runs in a general area on the second floor.
I like the second option, less to deal with. But I dont know if its up stairs will it handle the air in all the rooms? So if my dog is in my room would the air purifier that is setup outside the room in a general area pick up the dog hair and any dust that is in my room?
