Overview
Four Core 300-RF style cartridges in one box, built for Levoit's Core 300 platform. The listing adds the P350 VortexAir alongside the Core 300 and 300S, and each filter carries a nylon screen, H13 grade True HEPA pleats and activated carbon.
The only meaningful difference from the two-pack is arithmetic. At the recommended 5-6 month interval, four cartridges is roughly two years for a single purifier, or about a year if you run two units. That matters if you have already settled on this filter and simply want to stop reordering.
- 4-pack of Core 300-RF equivalents
- H13 grade True HEPA media
- Listed for P350 VortexAir as well as Core 300
- Tool-free swap, no adapters needed
Who it's for
Aimed at repeat buyers and multi-unit households rather than someone trying a compatible filter for the first time. If you have not yet confirmed the fit in your own machine, a smaller pack is the safer first purchase.
What buyers say
From Amazon customer reviews.
Owners describe the same drop-in fit as the factory part, with no added fan noise and no loss of airflow. Long-run users note the cartridges hold up for months of continuous running, and several show heavily discolored filters at the five-month mark as evidence of how much they captured. Households with dogs and cats report a clear odor difference, and one reviewer with seasonal pollen allergies keeps these in purifiers throughout the house.
Strengths and trade-offs
Drawn from this product's published specifications.
- Four cartridges cuts reordering to a rarity
- Covers Core 300, 300S and P350 VortexAir
- Three-layer build including activated carbon
- Spares on hand when a unit signals a change
- Overkill for a single lightly used purifier
- Larger outlay before you know the fit suits you
- No Levoit warranty coverage as an aftermarket part
Performance notes
Filter media does not degrade meaningfully in a sealed bag, so buying ahead costs nothing but shelf space. In service, the pleated HEPA layer is what traps fine particulate while the carbon bed handles smoke and cooking odor, and the carbon saturates on a schedule of its own regardless of how clean the pleats still look. That is the real reason to change on time rather than waiting until airflow drops.

Questions about the Colorfullife air purifier filters
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Does this 4-pack fit the Levoit P350 VortexAir?
Colorfullife lists the P350 VortexAir along with the Core 300 and Core 300S for this cartridge. Check the part number printed on your existing filter reads Core 300-RF before ordering.
How long will four Colorfullife Core 300 filters last?
On the suggested 5-6 month interval, roughly two years in one purifier or about a year across two units.
How should spare filters be stored?
Leave them sealed in the original bag somewhere dry. An unwrapped carbon layer starts absorbing household odors before it ever reaches the machine.
