When the Levoit wins
Small rooms and tight budgets. It costs less than half as much, is lighter and fits in a corner. Coway lists replacement filter intervals of 6 months for the deodorisation filter and 1 year for HEPA. Check Levoit’s page for its filter price before you buy.
When the Coway wins
Bigger rooms, and anyone who wants it to adjust itself. It covers about 60% more floor area at the same air change rate, and its auto mode changes fan speed based on the particles it detects.
