Our critiques of Levoit are nitpicky because the brand has such elevated attention to detail and quality for the price point. If you prefer aluminum or more expensively-packaged air purifiers, you may need to look at levoit air filter Dyson or another premium brand. As with any air purifier, some features leave more to be desired. The smart technology isn’t failproof, as a number of customer reviews note that the VeSync app momentarily crashes.
For users with allergies, an air purifier can lessen symptoms and help you breathe easier—a big sigh of relief if frequent cleaning just hasn’t been cutting it. We appreciate that this home air purifier has a wide variety of fan settings, perfect for many settings and situations. It’s also quiet enough to be unnoticeable when holding conversations, and the sleep mode doesn’t disrupt our sleep. Plus, for an air purifier under $100, it’s one of the more affordable home air cleaners that still offer an array of features. What separates the best air purifier from other compact options is its 3-stage filtration system. Between the three stages, the Levoit air purifier promises to trap at least 99.97% of particles as small as 0.3 microns in size, including animal fur and dander, large and fine dust particles and pollen.
The theory is that ozone, which is highly reactive, neutralizes or breaks down pollutants. Setting aside the dubiousness of that claim, even low levels of ozone can be harmful . It’s crazy to introduce a new pollutant when the goal is to reduce pollution overall.
Levoit is one of our favourite air purifier brands for small rooms. This allows people to use them in bedrooms and levoit air filter home offices without any interruption. Of course, it’s not just the appearance we love about Levoit air purifiers.
The display tells you how dirty or clean the air is with the PM 2.5 reading; that’s the amount of particulate matter per 2.5 micrometers in a cubic meter of air. For the less scientifically-minded, there’s also a color-coded indicator, going from blue to green to yellow to red. The latter indicated bad indoor air quality, when the PM 2.5 reading climbs above 115.
With a clean air delivery rate of 260 cubic feet per minute on high, the Core 400S is slightly more powerful than our top pick, the Coway AP-1512HH, which has a CADR of 240. In practice, that doesn’t make much difference, and indeed the Core 400S delivered numbers almost identical to those of the AP-1512HH in our testing, reducing 0.3-micron smoke particles by 99.1% in 30 minutes on high. But it also draws twice the electricity (16.1 watts versus 8.1 watts) and moves more air per minute on that setting than the AP-1512HH does on its medium speed, so that’s not surprising. In short, we don’t consider the Core 400S’s 30-minute superiority to be a meaningful advantage. In 2018, we declared the Blue Pure 211+ “the stiffest competition we’ve found for the Coway AP-1512HH Mighty,” our long-standing top choice for general use.
