AHAM, or the Association of Home Appliance Manufacturers, independently tests products to ensure their efficiency, as does the EPA (Environmental Protection Agency). The HPA5100B air purifier has been tested for efficiency in reducing smoke, dust, and pollen in the suggested room size of 190 square feet. And it’s also been tested for energy efficiency and received the EPA’s Energy Star® Rating. In addition, it received a CADR or Clean Air Delivery Rating of 4.8.
The Coway Airmega 250 is the larger, more powerful sibling of the Coway Airmega 150. It’s equally attractive, but it’s only slightly more powerful than our top pick, the Coway Airmega AP-1512HH Mighty, yet it costs $200 more. One standout test finding was that the 211i Max is remarkably quiet, particularly for a machine of its capability. On the high setting, it barely broke our 50-decibel limit for comfortable conversation, sleep, or TV watching. On its four lower speeds, it measured a barely noticeable 41 decibels or less.
The noise may also be an indicator that it’s time to replace the air purifier’s filter. Room air purifiers can often run loud when their filters contain high amounts of airborne particles. This can block the pores in a filter and stop the air from passing through efficiently. Your air purifier will alert you to a dirty filter by flashing its filter change indicator light.
I have tried dozens of air purifiers, and this is the one I use in my home. Smog, smoke, allergens and even viruses have homeowners wondering about indoor air quality—and what they can do to improve it, especially as they spend more time at home. And with my honeywell purifier own recent move to the Denver metro area, I understand the need for a solution to poor air quality days. That’s why I was excited to write a Honeywell air purifier review for the HPA300 model. We’re giving you the full scoop on this easy-to-operate machine.
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.
If you plan to use it in a smaller space, the HPA200 or HPA100 might be a more affordable option. Reflects how intuitive and easy the controls are to use, carrying ease, ability to remove the filter, and filter life indicator.

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 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.
You’ll also want to make sure nothing is blocking the grilles either in or out of the device. Nothing should be resting on top of the outflow, and nothing should block the intake grille. Lastly, if the device is on Turbo or Auto mode, it may run the air honeywell air purifier purifier at a higher fan speed which is louder. The Honeywell Quietcare and Enviracaire air purifiers contain a HEPA (High-Efficiency Particulate Air) filter that can remove 99.97% of all particles as small as 0.3 microns in size from passing air.
