The Levoit Core 300-P / 300S-P uses the Core 300-RF (Levoit 2-Pack Replacement Filter for Core 300-P / 300S-P).
Is the Core 300-RF True HEPA?
Yes - the Core 300-RF is a True HEPA filter, meaning it's rated to capture at least 99.97% of 0.3-micron particles.
How often should I replace the Core 300-RF?
About every 8 months under typical use, or sooner if airflow drops or your purifier's filter indicator lights up.
Should I buy the OEM filter or an aftermarket one?
The genuine Levoit Core 300-RF is the safe, exact-fit choice. A cheaper aftermarket filter can fit the same slot too - check reviews for real-world fit and filtration performance before buying, since air purifier filters generally aren't independently certified the way NSF-listed water filters are.
