Levoit Core 300 Air Purifier

Levoit Core 300 Air Purifier

We tested the Levoit Core 300 air purifier and gave it the top rating for odor control. In just 30 minutes, it also removed 99.97% of airborne particles 0.3 microns or larger, making it the most efficient purifier among the group. Additionally, the Core 300 is one of only two purifiers that kept our test sponges dust-free throughout the entire testing period, making it a great choice if you want to reduce allergens in your home.

We tested the white Core 300 air purifier, which comes in a few colors. A well-designed control panel and app complement its sleek, modern design.

Despite being one of the most expensive air purifiers in our review, it provides exceptional purification and includes a 5-year warranty. An excellent choice is the Core 300 if you can spend this much on an air purifier and don’t mind replacing the filter every six months or so.

Yes it has the standard filter in it. Just have to open the unit and take off the plastic bag around the filter.
I don’t know if there’s a way that it works better but it’s big enough for the floor and probably too big to look right on a table. We have ours sitting on top of a microwave because we haven’t yet unpacked from our move, but I plan for it to be directly on the floor eventually.
