using blueair.

cannot give you any recommendations because this is my first air purifier.

blueair 3410, iinm 1.4k something. took me two months ++ to do research on air purifier.

i buy for my newborn daughter and i actually having sinus problem since i was kid.

i put this in our bedroom. thinking to buy another high end version to put in living room, iinm need 4k for that lol.

you need to pay attention to its CADR reading when buying air purifier.

same like buying aircond, always buy the model higher tier than the recommended room size so your device won’t need to go full force blowing everytime. eg you calculate you need 1.5hp for your room, but you should go for 2hp aircond so it’s powerful enough to cool down your room quickly.
