Levoit air purifiers use the VeSync app for advanced control.However, there can always be connection problems, so here are some solutions that can help with the connection problems. Still, Levoit air purifiers are very easy to use and maintain, but there is always something to miss, so I have written this simple how-to and troubleshooting guide, which I believe can be helpful if you own a Levoit air purifier. In 2019, we purchased a Molekule Air—the company’s iconic original purifier—and found it to be the worst air purifier we’ve ever tested. Its performance on particulate pollution was dismal, and absolutely unacceptable in an $800 device. We later learned that many of the company’s advertising claims were found to be baseless, and Molekule subsequently retracted almost all of them.
Visually, the 200M differs from the AP-1512HH in that it has a square grille instead of a round aperture; like the AP-1512HH, it’s available in both black and white versions. Previously, we dismissed the 200M because it was significantly more expensive, but the prices of this model and the AP-1512HH have evened up recently. We advise anyone debating between them to compare their prices and purchase whichever model you prefer. 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 at whatever speed you want, and you get to sleep or watch TV in a nice dark room.
And it performed very well in our tests, as you might expect when you run a large-space machine in a small room. However, on its medium-high and high speeds, it produced a persistent rattle that we could not ignore, nor could we fix the problem by repositioning the machine and making sure that the filter was properly seated. That performance further bolstered our belief that the Air Pro’s HEPA filter, not its PECO technology, is doing most of the particulate removal. Using ACH to categorize air purifiers overcomes a common problem in the way manufacturers rate their air purifiers in their advertising. Most offer instead a square-footage rating, presumably because it’s easy for a prospective customer to take their room’s dimensions and then pick a purifier accordingly.
The Levoit brand has even earned top ranks in our Real Simple in-house testing. Keep the windows closed while it’s running and place the air purifier as close to the middle as possible, a foot away from furniture and walls. Depending on the size of the room, even an air purifier designed for small rooms might be overkill if, say, you place them in an at-home office. You want something like the tiny, yet efficient Holmes Desktop HEPA Air Purifier. You’ll also want to take a look at how often your filter need to be replaced .
We noted this is a downfall of all humidifiers—no matter their size or price range—but still think it’s worth mentioning as a minor drawback. The humidifier’s tank is especially tricky to refill because it is completely open, which allows for water to slosh over the sides if you’re carrying it a long way. While some parts of this humidifier are dishwasher safe, the filter takes a while to dry and does drip water when removing it. However, despite these inconveniences, this humidifier-air purifier combo is still a solid option, especially if you’re seeking a customizable, high-tech option. This humidifier was easy to set up and unbox, and we appreciated how simple it was to refill.
We tested dozens of humidifiers in both The Lab and real-world home settings to determine the best models for every room in your home, including options that double as air purifiers and fans. Our testing processes included extensive research, 48-hours of monitored lab testing, levoit purifier and up to six months of regular use in homes. Based on our testing results and Dr. Spaeth’s insight, the Levoit Classic 300S Ultrasonic Smart Humidifier was the clear winner because of its compact, modern design, intuitive touchscreen features, and easy-to-clean tank.
When you turn out the lights, the air purifier will even dim the brightness of the interface automatically, so it won’t bother you in your sleep. If you want to save some cash, you could instead go with the Govee Smart Air Purifier for $67 after clipping the on-page coupon. Here you’ll get Alexa and Assistant integration with a similar HEPA H13 filter to trap airborne particulates. It too has a 360-degree air intake to process the air of a 904-square foot room every hour with four different fan speeds that can be set on the purifier itself or through the Govee app. You can even set a schedule for the purifier to follow, like for it to only be on while you’re out of the house, using the app.
(You can read about the saga in our reports from February and June 2020; the Air was then known as the MH1.) That year we also tested a Molekule Air Mini and judged it to be similarly poor. That said, after we created the abnormal smoke conditions at the outset of the tests, from then on the New York test room was subject to only the natural, ambient air conditions levoit purifier and whatever leakage infiltrated the test room. And in that test, we learned that we had to run the machines on high to get meaningful purification . The 200M shares the AP-1512HH’s display-shutoff feature, which we value highly because it turns off the overly bright air-quality indicator lamp and makes this model much more conducive to bedroom use.
This technology helps the machine clean every square inch of indoor air. Ease of use refers to just how user-friendly and intuitive each machine is to operate. The first thing we did was get out a stopwatch and time how long it took to go from the unopened box to have the machine up and running. Needing minimal effort to assemble, it only took our testers two minutes to get the Core 300 set up. Finally, our incense smoke test evaluated how well the purifier performed after burning five incense cones simultaneously.
We only had to refill the water tank every three or four days, and it operated consistently on the automatic setting without any issues. The three mist settings and separate directional mist output also allowed us to ensure the whole room was easily reached. We did end up placing this model on the floor of a room, despite the manual’s instructions, and have not had any issues with the placement.
