Review on Flintar Core P350-RF H13 True HEPA Replacement Filter for LEVOIT Core P350 Pet Care Air 🐾 Purifier - 3-in-1 H13 True HEPA & Odor Removal Activate Carbon Filter for Pet Family - 1-Pack by Mack Douglas

Waste of money. It fits perfectly but the airflow is definitely not the same as the OEM filter. After using this filter for over a month it just doesn't clean the air like the OEM does. It seems too restrictive and makes the fan noise louder. I had to clean (vacuum) the OEM pre-filter about every week or so because it picked up so much dirt. After a few weeks of work, there is almost nothing left of it. So spend the extra $10. and just get the real thing! I just ordered an OEM filter and can't wait to receive it. The Levoit machine works great but not with this aftermarket filter.
