Core 300 Pet Care Replacement Filter for LEVOIT Core 300/ Core 300S/ Core 300-P/Core 300S-P/Core P350 Air Purifi-ers, 3-IN-1 H13 True HEPA Filter, Compared to Part# Core 300-RF, Yellow (2 Pack)

works great

Bought these for my 300S that has the air quality sensor. Typically when I cook it goes up to around 300. When I turn this on, after about 20 minutes it's close to zero. Definitely works.

These filters are just as good as the original units. Very pleased.

We love our Levoit but during allergy season, have to replace the filter more often. These are a great value.

Perfect fit for my purifier. Wife and I are very sensitive to dust and pollen, and we haven't noticed any difference between these filters and the "brand name" ones.

Perfect fit for the air purifier I got, and much cheaper than purchasing at the store.

Quick and easy transaction from Amazon. A quality product!

But because they're off brand, you will get a error reading on the air purifier. They work fine tho.

I bought these as I was looking for cheaper alternatives to the branded version.These are okay if you don’t have a long haired German Shepherd who is shedding, or any pet really. Or live in a house that’s particularly dusty. Or it’s spring and it’s hayfever season.Basically; they’re alright, they take the edge off, but I still wake up feeling like I can’t breathe. Next time I’m just going to save my sinuses and buy the branded version.
