Replacement filters cost $19, and if you stick to the six-month replacement schedule, they add up to just $171 (nine filters) over the course of five years. The total five-year running costs are thus just $200, about 60% less than the costs of the
Levoit Core 300. Add in the Blue Pure 411 models’ quiet operation and good looks, and they are an attractive option for small spaces. It’s quite small at 14.5 inches tall and 8.5 inches wide, so it fits on a bedside table or the corner of a desk.
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.
The Levoit LV-PUR131 has budget specs but typically costs twice as much as our budget pick. It’s an attractive machine, too, with its simple cylindrical form and tweedlike fabric covering (which also acts as a prefilter; you can launder it to keep the prefilter performing at its best). The purifier comes standard with a gray covering, and several other colors “inspired by the natural landscapes of Scandinavia” are available for purchase separately. We have tested and reviewed the Molekule Air Pro and Air Mini+, and will be reviewing several other purifiers soon. Warm mist humidifiers are less common, but a good choice for plants that thrive in a hot and steamy ecosystem.
In these tests, which lasted for 65 minutes, he used the first five minutes to get a baseline reading of the ambient air conditions, following that with the burning of five matches and a full hour of measurements with the purifiers on. As always, Tim ran each purifier twice, once on high and once on quiet/medium. For a general-purpose air purifier, we look for at least 98% removal of smoke particles in 30 minutes on high, and at least 85% on quiet/medium, in our test rooms. Large-space purifiers should do at least as well on high and top 90% on medium. We do not dismiss purifiers that have ionizers in addition to HEPA filters, but we don’t look for that feature.
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.

Finally, our incense smoke test evaluated how well the purifier performed after burning five incense cones simultaneously. We found that the purifier absorbed an impressive 96% of particles measuring 0.3 microns, 87% of particles smaller than 2.5 microns, and 98% of particles measuring smaller than 10 microns. Because the Levoit H132 only uses a high-efficiency particulate air filter (HEPA), it doesn’t create harmful ozone (opens in new tab) in the home, unlike other types of air cleaners.
(I was 20, what do you expect?) I remember feeling mildly not great for weeks before I moved out of that apartment and just accepting it. When I left, I felt better within a day or two, but I never had a flash of realization about how stale my air had become. Most reviews are positive, with users praising the purifier as convenient and highly efficient at reducing the symptoms of allergies. Customers particularly like how quiet the purifier runs, even at the highest setting.
Indoor allergies and my experiences in graduate school definitely were in mind when I finally decided to purchase an air purifier after I moved to New York City. Unfortunately, the Levoit H132 didn’t quite live up to expectations when it came to testing how well it absorbed particles, consistently falling some way below the 99.97% expected from a device with an H13 HEPA filter. However, running the purifier for longer periods may yield better results.
Air purifiers are excellent tools for filtering out airborne pollutants and improving your indoor air quality. These devices can reduce the presence of pet dander, dust mites, allergens, air pollutants and more in your home. They are especially popular during spring to help with hay fever and allergies.
