Buying Guide: Getting the Right Replacement
Keep these points in mind before you buy.
Genuine or compatible
Match the exact model and filter part number. Some brands, like Levoit, say their filter-life indicators are built around genuine filters.
Airtight fit matters
A filter that does not seal lets air bypass it; genuine parts are cut to the purifier’s exact frame.
Change it on time
EPA notes all filters need regular replacement, and a dirty, overloaded filter will not work well. Follow the maker’s interval and the purifier’s indicator.
Replacement Tips
Fit it right:
- Check the model label.
- Match the part number.
- Seat the gasket evenly.
- Reset the indicator.
