According to the air quality monitor, the Honeywell PowerPlus removed all of the particulate matter from the air in the room within an hour of the incense burning out. All Honeywell air purifiers come with a permanent true HEPA filter, an Intelli-Check Monitoring System, and patented SurroundSeal technology. In addition, it ensures that the air passing through the Honeywell air purifiers passes through all of the filters. Altogether, these features ensure the air in your home will be clean and free of allergens.
Smoke particles are right in the 0.3-micron size range—the hardest size to capture—that’s used as the HEPA test standard. If a purifier does well on smoke, it will do even better on larger particles like dust and pollen, and—somewhat paradoxically—on smaller particles like honeywell humidifier bacteria and viruses. Since 2017, I have conducted extensive reporting on and real-world testing of air purifiers in my New York City apartment and in Wirecutter’s New York and Los Angeles offices. I have spoken with manufacturers, engineers, academics, and experts.
The Alen BreatheSmart 75i is Alen’s most powerful unit, capturing the largest numbers of particles in your air in the shortest amount of time. The 75i is ideal for living rooms, open concept spaces, and other large rooms up to 1,300 sq. Alen air purifiers offer superior performance through the combination of a powerful fan, quiet motor, and advanced filtration technology to deliver and maximize airflow while minimizing noise.
For those factors, we measure how much noise the purifiers make when running, and we calculate their long-term costs for energy consumption and replacement filters. We consider the ease of operation and maintenance, the presence or absence of distracting lights (which can disrupt sleep), the simplicity of the controls, and their physical size and aesthetics. We’ve pushed honeywell humidifier this machine beyond its on-paper limits in various ways—including running its filters 24/7 for two years, twice as long as recommended—and it has never wavered or weakened. It offers great value on initial and long-term costs, and its compact form, quiet operation, and display-light shutoff make it especially well suited to using it in a bedroom or living room.
Our years of testing have proved that a good air purifier creates and maintains excellent air quality when it is simply allowed to run continuously on a moderate setting. As a result, we do not insist that our picks have smart control options. But many members of our paid tester program have told us how helpful the ability to control appliances via an app or by voice command is for people with mobility or dexterity issues. In short, smart capability isn’t necessary to get clean air, but it can add meaningful utility to a purifier. If this is the first time you’re using a Honeywell Portable Air Purifier, you’ll want to ensure that you have removed the protective plastic wrap from the air cleaner’s filters.

Deep-clean your atmosphere with the Levoit VeSync Core 200S Plus Smart True HEPA Air Purifier. 3-stage filtration removes at least 99.97% of airborne particles 0.3 microns in size, and keeps dust, odors, honeywell humidifier and more from polluting your space. With the free VeSync app, you can set timers and schedules, monitor air quality and filter life, adjust settings, and sync with third-party voice assistants for hands-free control. The air purifier is ideal for rooms 178 sq ft and can clean the air twice every hour in rooms as large as 445 sq ft.
Since the candle test, I’ve used it for trash odors, pizza drippings in the oven, burned toast, that oily smell from frying chicken wings and even neighbors’ cigarette smoke from the sidewalk outside my window. I expect this will come in handy on poor air quality days particularly during the summer months. The HPA300 boasts 4.8 air changes per hour in a 465-square-foot room.
