However, on its medium-high and high speeds, it produced a persistent rattle that we could not ignore nor fix by repositioning the machine and confirming that the filter was properly seated. The Levoit Vital 200S is another excellent purifier and is similar to the Coway Mighty in both capability and livability. It excelled in our smoke tests, and it resembles the Mighty in energy usage and noise output (meaning it’s highly efficient and very quiet on its lower, everyday fan settings).
Air purifiers are fundamentally simple machines—little more than a fan and a filter. Yet a well-designed purifier can capture virtually all airborne allergens, such as pollen and mold spores, as well as bacteria, viruses, and smoke. All Honeywell air purifiers come with a permanent true HEPA filter, an Intelli-Check Monitoring System, and patented SurroundSeal technology.
If you’re not using it for a while, Honeywell recommends removing the filters and storing them in airtight plastic bags to prolong their lifespans. The filters actually come wrapped in airtight plastic bags to ensure freshness, so don’t just take it out of the box and turn it on—remove the plastic wrapper from each filter first. The number and placement of filters differs depending on which model you get, so be sure to read the instructions.
To clean allergens like pet hair and pollen from surfaces, you need a vacuum cleaner or a dust mop. To reduce viruses and bacteria on surfaces, it is usually sufficient to clean them with soap, detergent, or an all-purpose cleaner. Since 2017, I have conducted extensive reporting on and real-world honeywell humidifier 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. And I have also lived with most of our picks, running them 24/7 for months—and sometimes years—in my apartment.
Breathe easy and reduce airborne allergens with this Honeywell air purifier. Filters are not just replacement parts, they are the water and the air that our families drink and breathe. Our ClearChoice fridge and AIRx HVAC filters are made in our factory and headquarters here in Indiana, with great attention to quality.
Both Honeywell QuietCare and Enviracaire Air Purifiers (the primary division between smaller- and larger-size s) utilize two types of filters. The true HEPA filter removes up to 99.97% of common household particles as small as 0.3 microns in size from the air. The carbon pre-filter traps larger-sized air particles, including dust, lint, fibers, and pet fur, while also deodorizing the air. Overall, each of these Honeywell air purifier filters helps to keep the air in your home clean and fresh all year long. There are just so many more fun things to do, and so I rely on air purifiers to keep the sneezing and itchy eyes under control. It removes allergens and odors without making too much noise or requiring much maintenance.
