Of the two, the TP04 performed better, but neither model measured up well against our top pick, the Coway Airmega AP-1512HH Mighty, and our large-space pick, the Blueair Blue Pure 211+. The TP04 reduced particulate pollution by 86.6% in 30 minutes on its highest setting; compare that with 98.9% and 99.3% from the AP-1512HH and the Blue Pure 211+, respectively. On medium—which
we set as fan speed 6 of the 10 speeds available—the TP04 managed just 74.4% reduction. The Coway and Blueair models, in contrast, scored 87.6% and 99.2%, respectively. The Dyson Pure Hot+Cool HP04, which incorporates a space heater as well as a purifier, in theory should have performed somewhat better than the TP04 because it can move a slightly greater volume of air.
Below, find the best deals on air purifiers for your home, all of which have True HEPA filtration, from Dyson, Molekule and more. From splurge-worthy to budget-conscious, these air purifiers offer you clean air that brings relief. An air purifier can help relieve allergy symptoms, whether they’re seasonal or perennial. Instead of entering your body, airborne particles enter the air filter, leaving you with crisp, clean air in your home.
It’s particularly amazing in winter, when the last thing you want to do is keep the windows open for the freezing cold air to clear everything out. Recommended for extra large rooms, this HEPA air purifier has 4 air cleaning levels to provide cleaner, fresher air. Clear the air of allergens, smoke, dust and pollen with the touch of a button. The
Levoit Vital 100’s compact design makes it perfect for your bedroom, living room, kitchen or any large space. The High Efficiency Particulate Air (HEPA) filter standard means a filter can capture 99.97% of the tiny, most-difficult-to-trap particles in the air — tiny means 0.3 microns in diameter, the size of some virus and bacteria bodies.
If none of the above is possible (or if it’s not enough), consider room air purifiers. Under typical conditions, we recommend running air purifiers 24/7 on their highest “quiet” setting—which we define as 50 decibels (dBA) or less. That generally means the medium setting on three-speed purifiers, or the high-medium setting on four-speed machines; specifically, that means avoiding the “automatic” setting that some purifiers come with.
In a dark room, the lamp can be a distraction, and we wish this model offered an option to shut it off on every setting, as you can on the Coway AP-1512HH. 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. 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 appearances) and purchase whichever model you prefer.
