Levoit Core 600S Smart Air Purifier

Most air purifiers people own are rated for a box room and then placed in an open-plan living space, where they achieve very little. The 600S is rated to just under three thousand square feet an hour, which is the first honest number in this category, and it is quiet on the low setting — the setting it will actually live on. Twenty-five thousand ratings at 4.6. Filters are the running cost, about every six to eight months. Skip the smart features if he will not use them; the dial on the top does everything that matters.
