Fortunately, Honeywell air cleaners contain a long-life HEPA filter which will typically last anywhere from 3 to 5 years or longer. Honeywell’s pre-filter will last up to an average of three months. The bulk of the pre-filter is a non-woven polyester which will continue to remove large, visible particles well beyond three months. After three months, the impregnated carbon, which is solely responsible for the odor and smoke removal, will have absorbed as much as it can.
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. This made it one of the fastest cleaning purifiers we tested. It automatically boosts the fan speed to clean quickly when the air quality is poor and slows when it’s good. The PowerPlus is also easy to maintain and includes an indicator light that tells you when to replace the widely available filters. Set on high, the AP-1512HH reduced the particulate concentration by 99.9% in the first hour.
It’s been working flawlessly in our first year of long-term testing in a New York City apartment. 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. The 200M has a square grille rather than a round one, but that’s the only major physical difference. If you prefer the 200M’s looks or you find it at a better price, we recommend it.
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. So far, since I first plugged air purifier in the master bedroom, I noticed how quiet it is! Thanks.Please use my $5.00 towards new filter I wish to order. The room smells more smoky than the first model, even though it isn’t. Technically, this thing should catch smaller particles though (since it’s a True HEPA filter).
Simply put, the activated carbon cannot hold any additional smoke or odors after three months or so. Overall, I’m a little disappointed with the sound levels of each. I’d really like a purifier that’s truly quiet on the lower settings. It’s called “using one massive fan that utilizes honeywell purifier the maximum possible space”, and “designing an enclosure to minimize restrictions in airflow”. If you want to get really fancy, you can get into actual fan-blade design, well thought-out-bearings, and all that other fun stuff, but I’ll keep my expectations for the future low for now.
Because it’s turned into a mesh in most cases, it does catch large particles (like bugs, etc), but you could do the same thing with a piece of breathable foam, or a screen, etc. In any case, if you want to maintain the “freshness” part, you’ll have to shell out money a few times a year. If you don’t care about the freshness part, you could probably try washing/drying it, or cut up a screen on your own.
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 honeywell air purifier its lower, everyday fan settings). There are four fan speeds to choose from (versus the Mighty’s three), so it offers a bit more flexibility. However, the medium-high setting approaches our 50-decibel limit on acceptable noise, so it’s not clear that this is a meaningful advantage. 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 (versus, typically, a year).
In our testing with a professional particle counter, the Blueair DustMagnet 5440i performed no better than the much less expensive Coway Mighty. The T810 is yet another impressive purifier from Winix, closely resembling the Blueair Blue Pure 311i Max in its form, performance, and sleep-friendly display shutoff. It’s slightly louder, however, and considerably less energy efficient. Most air purifiers arrive with the filters installed—but they are also sealed in plastic wrappers. Open up your machine, unwrap the filters, and reinstall them.
It is generally recommended that the HEPA-Type filter of this portable air purifier be replaced every four months. According to a physician’s survey, doctors recommend Honeywell HEPA air purifiers more than any other brand. Honeywell air cleaners offer allergy and asthma relief at an affordable price.
If you try this hack, carefully seal the filter around its entire perimeter with clear, pro-strength packing tape—any gap would have let unfiltered air pass through, the same as on dedicated air purifiers. Doing all this may damage the fan’s motor, and we wouldn’t consider it to be a long-term solution for air-quality issues. But if you experience an air-quality emergency—say, regional wildfires creating a purifier supply shortage—it’s worth a shot. But it was louder, at 43 decibels, versus the Coway’s 39. It’s easy to forget the occasional obligation of replacing your purifier’s filters—so set a calendar reminder.
