Overview
A two-pack of aftermarket replacement filters cut for the Levoit Core 300 purifier body, sold against part number Core 300-RF. Each cartridge combines a nylon pre-filter screen, H13 grade True HEPA media and an activated carbon layer in one drop-in ring.
Buying filters is the recurring cost of owning a purifier, and that is the whole argument here. Colorfullife lists fitment for the Core 300, Core 300-P and the WiFi Core 300S, so one part number covers a household running a mix of those units. Two cartridges at a time works out to roughly a year of coverage on the maker's own 5-6 month replacement guidance.
- Cross-referenced to Levoit part Core 300-RF
- H13 grade True HEPA pleat pack
- Nylon pre-filter, HEPA and carbon in one ring
- Maker suggests replacement every 5-6 months
Who it's for
Sensible for anyone already running one or more Levoit Core 300 series units who resents paying brand prices for a consumable. It is not for owners of the Core Mini, Core 200S or Vista series, which take physically different cartridges.
Pros and cons
- Drops into Core 300, 300-P and 300S alike
- Carbon layer targets cooking and pet odors
- Two cartridges covers about a year
- Outer screen is vacuum-friendly between changes
- Not compatible with Core Mini or 200S
- Carbon layer is not rechargeable once loaded
- Aftermarket part, so no Levoit warranty backing
Performance notes
A purifier's real-world result is governed less by the media grade than by seal quality, since air that slips around the cartridge is air that never got filtered. The nylon outer screen catches hair and large lint so the pleated HEPA layer is not clogged early, and the carbon layer handles odor molecules that HEPA media passes straight through. Vacuuming the outer surface every few weeks slows the pressure drop that eventually makes the fan work harder.

Frequently asked questions
Will this Colorfullife filter fit a Levoit Core 300S?
Yes. The listing covers the Core 300, Core 300-P and the WiFi-enabled Core 300S, all of which use the Core 300-RF cartridge.
How often should the Core 300 filter be replaced?
Colorfullife rates each cartridge for at least 3 months and suggests changing at 5-6 months. Heavy dust, smoke or pet load shortens that.
Can the filter be washed and reused?
No. The HEPA pleats are not washable. You can vacuum loose dust off the outer nylon surface, but water ruins the media.
