Prices are from Levoit's store. The yearly cost above uses the standard filter; a dearer filter replaced on the same schedule raises it in proportion. A pre-filter is the outer layer that catches hair and large dust before the main filter.
When to replace it
- Follow the purifier's filter indicator rather than the calendar: it tracks actual use, and the brand's schedule is a maximum under normal conditions.
- Wildfire smoke, heavy cooking, pets and dusty rooms shorten a filter's life. A filter that looks grey or carries a smell is due even if the light hasn't come on.
- Third-party filters are cheaper, but the brand's performance figures only apply with its own filter, and on some purifiers the filter-life tracking only works with genuine ones.
