Levoit Core 300S vs Coway Airmega Mighty
Bottom line
Both are strong, ozone-free picks with independently checked airflow, so this comes down to your room. Pick the Coway if you are filling a medium living space and want the extra output and sealed HEPA. Pick the Levoit 300S if it is a small bedroom - it is the better value there.
These are the two units people usually land on when they want a good purifier without overspending, so the good news is you cannot really go wrong - the choice is mostly about room size. Both have their clean-air output checked by AHAM (the independent body that verifies how much air a purifier moves) and neither emits ozone. The Coway moves more air and adds a true sealed HEPA filter, which suits a medium room; the Levoit is cheaper, quieter, and plenty for a smaller one.
