Air purifiers were an easy thing to be sceptical about until there was a newborn in the house. The Core 300S is Levoit's compact smart model, and it is the size that actually fits in a bedroom.
Levoit launched into Harvey Norman in Australia in April 2026, which put the range in front of a lot more people than the online-only years did. The Core 300S is the compact one, app connected, sized for a bedroom or a small living area rather than an open plan whole-house job.
Why one ends up in a family house
The case is not the marketing about particles, it is the boring stuff. Dust in a Queensland house is relentless, hay fever season flattens at least one person here every year, and a baby's room is the one space where you will happily spend money to remove a variable.
The thing to weigh before buying any purifier is the ongoing cost. That is not a reason to avoid one, it is a reason to do the three year sum before you commit.
