Hi guys, we live 200m from a major highway (M3) in Melbourne and we have two kids under 4. Bit concerned about the air quality. Don't mind investing in something better if worth it. The house is pretty airtight and we ventilate the house a bit early in the morning when the highway is quiet.
We are looking at a couple of Xiaomi and Blueair 680i as we need to cover our living area and kitchen which is about 60sqm. Any thoughts which one will be more suited for us? IQair is prabably overkill?
