A child lock function keeps wee ones from messing with the settings. The display shutoff keeps its glowing LEDs from disrupting sleep. One version adds Alexa compatibility for remote control and monitoring, although this feature bumps the price up by a bit.
This is standard info in an air quality monitor, but it’s something we’ve rarely seen integrated into a purifier. The app also lets you remotely monitor and adjust the honeywell humidifier operating settings. We’ve tested more than 60 air purifiers in the past nine years, and the exceptional Coway Airmega AP-1512HH Mighty is our top pick among them.
The HPA300 boasts 4.8 air changes per hour in a 465-square-foot room. It stands at just under 2 feet tall, and it’s designed to be placed on the floor. The instructions advise putting a mat or rug beneath it to prevent carpet stains. Also keep in mind that it’s not for use in bathrooms or other damp locations.
The Blueair Blue Pure 311i Max is another stellar air purifier comparable in capabilities to our Coway picks. It’s extremely energy efficient, drawing just 30 watts on its highest setting (out of four), versus the Coway Mighty’s 68. And it’s a fantastic performer, reducing smoke levels by 99.9% on high and 99.7% on medium-high. Air purifiers can help to remove harmful pollutants and allergens from the air, leading to improved indoor air quality and a healthier living environment.
The Blueair Blue Pure 211i Max, meant for large spaces around 500 square feet, is a stellar performer, reducing smoke levels in our test room by more than 99.9% on its high and high-medium settings. In spite of the power, it’s extremely energy efficient and quieter than you’d expect. You can shut off the display while it runs, which helps if you’re light sensitive while trying to sleep. Its air-quality sensor reads your room’s particulate-pollution levels at 1, 2.5, and 10 microns (aka PM1, PM2.5, and PM10—broadly equivalent to smoke, dust, and pollen). An app remotely monitors its readings and can control its settings.
Consider whether you actually need a large-space purifier, though. If you’d be using a Blue Pure 211+ to purify a space that these smaller machines could handle, that’s wasted electricity. The filters have a shorter replacement cycle than those of the Mighty, and many of our other picks, at six to nine months depending on usage honeywell humidifier (versus, typically, a year). The machine measures actual filter usage, not simply the elapsed time since the last filter was installed, so if you don’t run your machine all the time, you’ll get more life out of them. In the long term, though, filter replacements will likely give the 311i Max slightly higher running costs.
Using bunches of incense sticks, we created a thick haze of smoke in the room—which was four times larger than what the Coway is designed to be used in. It still dropped the pollution by 70% in under an hour, performing as well as some purifiers intended for extra-large spaces. The Coway Airmega 200M is virtually identical to Coway’s Airmega AP-1512HH Mighty in every important respect. They’re equivalent in noise and performance measurements, their filters are interchangeable, and their similar controls allow you to shut off the display lights.
Many of today’s air purifiers feature an Auto mode that adjusts the fan speed based on the air quality. Though it’s Energy Star-certified, the Honeywell HPA300 True HEPA Air Purifier doesn’t have an Auto mode and had high power consumption in our tests. Despite its negatives and costs, we strongly recommend the Honeywell PowerPlus True HEPA Air Purifier because it can effectively honeywell purifier and efficiently remove particulate matter and VOCs from the air. It has minimal maintenance needs, and the filters are widely available. I have tried dozens of air purifiers, and this is the one I use in my home. To test air purifiers, I light an incense stick in a 200-square-foot room, burn it for 15 minutes, and then turn the purifier on and run it on high for two hours.
The replacement alert on the display reflects actual usage, though, not simply the elapsed time since the last replacement, so if your purification demands are low, you’ll wind up on the long end of that range. We normalize the test data so that each machine’s peak reading of 0.3-micron particles represents the maximum particulate load it faced. We describe its overall performance as its maximum reduction of particulates relative to that load.
Genuine Honeywell pre-filters, True-HEPA, and HEPA-Type replacement filters help remove allergy provoking dust, pet dander, pollen, smoke and mold spores from the indoor air you and your loved ones breathe. Honeywell air cleaners and air purifiers filter microscopic particles and allergens to help make your home a healthier place to live with cleaner air to breathe. Make sure to replace your air purifier filters, air cleaner filters, air cleaner pre-filters, HEPA and True-HEPA filters as recommended and with genuine Honeywell filters so they can work correctly! Shop our Honeywell replacement filters below and order your air purifier filters and air cleaning filters online on our secure servers. 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.
