Category questions
What size air purifier do I need for a large room
Check the clean air delivery rate and suggested room size. As a rough guide you want the purifier to be able to cycle the air in the room several times per hour on a realistic fan speed, not only on the loudest setting.
Should I use one big purifier or a couple of smaller ones
In some layouts two smaller units at opposite ends of a space can work better than one big purifier, especially in L shaped or open plan rooms. It also gives you flexibility to move one into a bedroom at night if needed.
