At least 99.97% of airborne particles will be captured in this filtration system. This includes things like fine dust, cooking smells, dander, and more. The numbers listed in the table above represent the performance of each air purifier after an hour of running in a closed room. There’s a washable pre-filter first, designed to capture large particles like pet hair, dust, or lint. This pre-filter can be removed every two to four weeks, gently vacuumed with a vacuum hose to remove the dust, and hand-washed with a mild detergent and rinsed.
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.

I’m not the most gifted chef, so sauteing various foods usually results in a house full of smoke and various smells that can be, well, off-putting. Our kitchen space connects to our living room, so there’s no escape from culinary mishaps. While no machine we tested entirely eliminated the odor left behind from the smoke, the Core 300 seriously reduced the smell and greatly improved visibility.
Levoit Air Purifier – New Vs Used FilterFortunately, the filter reset indicator will let you know when it’s time to change the filter. In that case, I recommend that you download the levoit purifier VeSync app on your smart device and connect your Levoit to the app immediately after setup. This will give you many additional options and make it easier to use your air purifier.
That means it can clean the combined living areas of many open-floor-plan homes. It’s also an attractive, quiet-running machine, so it’s easy to live with. Its five-year cost of ownership—about $1,150 including the up-front cost and the annual cost of electricity and replacement filters—is comparable to that of most large-space purifiers. All that said, unless you need to clean an especially large space, levoit air filter the even quieter, smaller, and much more affordable Coway Airmega AP-1512HH Mighty is a better choice. The GermGuardian AC5900WCA was a stellar performer in our 2019 test, reducing particulates by 99.3% on high and 98% on medium. Those results actually beat the performance of the similarly priced Coway Airmega AP-1512HH Mighty, our top pick, despite the AC5900WCA’s slightly lower CADR numbers.
We have not been able to test it, but we are confident that it will deliver similar, excellent performance. On its medium and comfortably quiet everyday setting, it delivers 3 ACH, keeping the air extremely clean under normal conditions. Another highly rated air purifier topping critics’ and customers’ lists is the Coway AP-1512HH Mighty Air Purifier .
Levoit is one of our favourite air purifier brands for small rooms. This allows people to use them in bedrooms and home offices without any interruption. Of course, it’s not just the appearance we love about Levoit air purifiers.
If you’re looking for a more inexpensive option, we recommend this best-selling model from Levoit. It’s powerful enough to refresh the air five times per hour, though it’s smaller size lends itself to working in rooms up to 219 square feet. Most models circulate air through a HEPA (High-Efficiency Particulate Air) filter, and often more than one. HEPA filters are certified to trap particulate matter as small as 0.3 microns, which covers dust, pollen and most bacteria. Some purifiers boast a medical-grade Hyper-HEPA filter that will go down to 0.003 microns — enough to pick smoke out of the air.
A dehumidifier is the best option for rooms with high humidity levels, like basements. Pollution is just a high level term for particulates and VOCs in the air. I am doubtful it’s something we can include for every air purifier, but it’s perhaps something that we could do for at least a smaller group of more popular models. The design of any Levoit air purifier can be broken down by a few different factors, but many factors tend to overlap between models. The air quality in our living room has stayed within the Very Good range, with the exception of the one night when my husband accidentally included a stowaway roll of toilet paper with the laundry in the washing machine.
