The Honeywell S QuietCare Permanent, True HEPA Air Purifier with Germ Reduction removes at least 99.97% of common household particles from the air passing through the filter and helps eliminate common household odors. At $269 plus a yearly cost of about $110, the Honeywell PowerPlus True HEPA Air Purifier isn’t cheap. But when you consider how much air it cleans — a 637-square-foot room four times in an hour — it’s a great deal.
In a 35-minute test, we run the machine on its absolute highest setting. In a separate test, we use the highest setting the machine can run while keeping the noise below 50 decibels; this is around the upper limit of what would be tolerable for normal conversation, watching TV, or sleeping. The problem is that many manufacturers dramatically overstate their machines’ abilities. A lot of “living room” purifiers are barely powerful enough to keep a walk-in closet clear.
This means it filters the air up to 4.8 times per hour in a 190 sq. The purifier tobacco smoke rating is 114, while its dust and pollen ratings are both 140. The Honeywell HPA5100B InSight™ HEPA Air Purifier for Medium-Large Rooms gives you fresher air and Energy Star® rated operation. It delivers 4.8 air changes per hour in a 190 square-foot room while its Activated honeywell air purifier Carbon and True HEPA filtration captures 99.97% of microscopic allergens down to 0.3 microns. This quiet and powerful air purifier features InSight™ display, which lets you view settings from afar, making it perfect for use in medium-large size spaces. The Blueair Blue Pure 311i Max is another stellar air purifier comparable in capabilities to our Coway picks.
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. Accessibility meets efficiency with the latest iteration in a series of revolutionary Honeywell Air Purifiers. Honeywell InSight HEPA Air Purifiers provide visual enhancement via a new display panel that will illuminate when active. Select between four cleaning settings (Microscopic Particles, General Clean, Pollen and Turbo). Once you’ve chosen a cleaning level, the InSight HEPA Air Cleaner will illuminate that setting so that you know exactly how your portable air purifier is performing.
For best results, we recommend using only genuine and certified Honeywell filters and replacing them every 3 months as needed. The Clorox Medium Room reduced smoke levels in our test space by 98.1% on high and 95.9% on medium over the course of a 30-minute cycle. In a space that’s about 200 square feet or less, the Clorox Medium Room is a solid, inexpensive purifier with liveability features we honeywell humidifier usually only see on more expensive purifiers. Smaller purifiers tend to be less energy-efficient, but the Clorox is an exception, with lower long-term running costs than is typical for this size. A display shutoff and child lock on the controls make it easier to sleep near and suitable for nurseries and playrooms. A slightly pricier version of it is Alexa-enabled for remote or voice operation.
And to test the timer feature, I ran the air purifier for extended periods without a triggering odor. Set on high, the AP-1512HH reduced the particulate concentration by 99.9% in the first hour. With the purifier set on medium over the next two hours, the particulate load remained stable, varying no more than 0.1%. In the first hour on high, the Airmega 400 also reduced the particulate concentration by 99.9%, and thereafter the particulate load varied by no more than 0.2% on medium. In these tests, the purifiers handled normal ambient air after we raised the smoke levels at the outset.
We compute the air changes per hour, or ACH, they can provide in hypothetical rooms of 150, 350, and 500 square feet (assuming an 8-foot ceiling height). 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.
So the Air Pro is effectively four times noisier than what we consider to be acceptable. It’s easy to forget the occasional obligation of replacing your purifier’s filters—so set honeywell purifier a calendar reminder. Purifier manufacturers typically recommend replacing them annually, but check the manual; some models call for less frequent or more frequent replacement.
