The initial purpose of the Levoit Vital 200S air purifier was fulfilled, but I still continue using it every day. I’m allergic to dust and have OCD — in a nutshell, I’m that person fighting dust bunnies in Swiffer commercials, just a lot more anxious. The built-in AirSight Infrared Dust Sensor automatically takes air quality readings to determine if the air quality is Very Good, Good, Moderate, or Bad.
To do this, you typically open the lid on the bottom of the device and remove the filter. Note that the cover on the LV-H128 and LV-H126 models is not on the bottom. You can customize the result by air purifier wattage and by state. In the case of the calculations we shared on this page, we used California as our base state for energy prices. On levoit purifier Auto mode, a built-in dirt sensor or other inputs will allow the fan to run on a higher fan speed when the air is determined to be dirty and on a lower speed when clean. The Coway Airmega 300, our previous pick for large spaces, is similar in specs to the Blueair Blue Pure 211+, our current large-space pick, which typically costs much less.
The Levoit brand has even earned top ranks in our Real Simple in-house testing. The replacement filters start at $30, while most value brands charge $20 or less. Still, there are a few things we’d change about this product in a perfect world.
Its small, sleek style allows the air purifier to blend in and travel easily into bedrooms, living rooms, and kitchens up to 129 square feet. Its compact and portable build allows you to filter out any unwanted smells or toxins from essentially anywhere in your home. Plus, it offers two night light settings and operates quietly to easily create your dream sleep experience. This technology makes it a lot easier to keep tabs on the quality of the air indoors. If you plan on using the Levoit app, you’ll be able to keep the air clean at all times, even if you’re not at home.
At night, for example, you can shut off its display, which features a far-too-bright air-quality indicator lamp. You do so by holding down the Ionizer button for three seconds—something Coway could frankly do a better job of making clear. The machine keeps running levoit filter at whatever speed you want, and you get to sleep or watch TV in a nice dark room. In 2018, Tim also tested purifiers in Wirecutter’s Los Angeles office, attempting to simulate wildfire conditions. We do dismiss air purifiers that rely on ozone to “purify” the air.
