Samsung AX90T7080 Questions & Answers

Hey Samsung, just bought a few of these. Do these have negative Ions in the gizzards? Will write a review when I get them! How many can one put in lounge room 15x12m? Bed room 9.5x7m? Is it unsafe to have too many in one room like with my UV-Neg Ion units? Also when using the "Smart thing's" App on my Galaxy S23 Ultra or Tab S8 Ultra, will the app pick them all up or will one be able to control them INDIVIDUALLY? Does one need to have these connected to the home network to be able to access the units via the WiFi? Thanks for your help!
