The 311i Max and 211i Max that now hold these spots are slightly higher performing and have improved energy efficiency and liveability features, but the older models are truly excellent in their own right. It’s easy to forget the occasional obligation of replacing your purifier’s filters—so set a calendar reminder. Purifier manufacturers typically recommend replacing them annually, but check the manual; some models call for less frequent or more frequent replacement. We appreciated some practical and user-friendly features we wouldn’t expect at this price.
Coway Airmega 400S Smart Air Purifier
It’s installed in the return part of the system where the air returns to the furnace before the air is heated or cooled. However, bigger homes need coverage for a large space to achieve clean air free of volatile organic compounds (VOCs) throughout the entire home. In addition to improving my home's air quality, I can drop my favorite essential oil on top of the purifier's essential oil cotton pad, and it will diffuse a lovely fragrance throughout my home.
What to Know About Air Purifiers Before Shopping
Having an air purifier in every room isn't necessary, depending on your specific air quality goals and the type of air cleaner you use. If you have a home with poor air quality, purchasing an air purifier for every room may work, but I recommend looking into a whole-house air purifier. Its SmartSensor technology detects airborne particles, automatically adjusting its fan speeds to clean the air. Our top pick is the Levoit Core 400S Air Purifier because it is extremely effective at filtering PM, such as smoke, as well as VOCs, specifically those emitted from household products.

Are there any downsides to air purifiers?
But because of its higher energy consumption, it costs more to maintain than our current budget pick, the Clorox Medium room. And it’s a tall, garish device that won’t blend into any decor outside of an Alien set. The huge and exceptionally powerful Medify MA-112 is surprisingly easy on the ears, registering as “quiet” on its low, low-medium, and high-medium speeds (39, 42, and 47 decibels). But at 28 inches tall and 15 inches wide, it’s best suited to large commercial or public spaces—like casinos, which Medify says use the MA-112 to counter the effects of cigarette smoke. In our testing with a professional particle counter, the Blueair DustMagnet 5440i performed no better than the much less expensive Coway Mighty.
During testing, we didn’t find that the filters collected any of the synthetic pet hair, so it may not be ideal if your furry friend sheds a lot. However, its effectiveness at improving the overall air quality in a short period of time leads us to believe that it would still lessen the negative effects of potential pet-related allergens. Since there's no range hood in the kitchen, we run the air purifier when cooking to reduce the smoke in the air.
Best Air Purifier for Large Spaces
The Clorox's CADRs of 206, 219 and 232 across smoke, dust and pollen make it well-suited for medium- to largish-sized rooms up to 320 square feet. At its lowest setting, I also found this air purifier to be quiet (41 dB), but it rose to an annoying 58.7 dB at its highest setting. It is very energy-efficient, though, using just 3.6 watts of energy at its lowest setting.
It offers great value on initial and long-term costs, and its compact form, quiet operation, and display-light shutoff make it especially well suited to using it in a bedroom or living room. 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. It’s also critical to maintain and upgrade your home’s heating and cooling equipment. “[Whole-house] filtration is the easiest retrofit opportunity by installing high-capture filters in HVAC systems,” says Sam Rashkin, chief architect of the U.S. To avoid noise disruptions, we suggest running the unit on its high-speed setting when you’re not in the room and turning it down to low when you’re nearby.
What exactly do air purifiers do?
Most manufacturers use the combination of both, plus UV filters and ionizers for maximum effect. It also comes with a simple user interface that gives real-time air quality updates and automatically alerts you when it is time to clean or replace your filters. You’ll also find controls for setting the fan speed, auto mode, sleep timer (up to 12 hours), and the negative ion generator. We were particularly impressed with the ultra-quiet operation of this air purifier—it’s easy to forget that it’s even running.
Since it tracks air quality over time, there's a chart of how your room's air quality has changed to help you understand potential causes. If you want more detailed information about your home's air quality or a specific PM 2.5 reading, this air purifier may not be the right choice for you. It doesn't display an exact air quality reading, and there is no app for in-depth insights. The sensor will adjust the speed of the fan according to the particle level, cleaning the air more quickly when the particle level is high.
It features a 90-degree oscillation that helps to cool off entire rooms more quickly and efficiently. Just keep in mind that this air purifier is most efficient in a sealed space, as opposed to an open-concept space. Additional features include a nighttime mode, a remote control, a filter change reminder, an air quality indicator, and an auto mode that adjusts to reach the right humidity level and reacts to air pollutants.
When it comes to whole-house purifiers, you first need to think about how large of an area you want to cover. If you are only looking to work with a smaller space, then you can get a smaller and less powerful model. If, on the other hand, you want to purify your whole house, then you will need a larger model, like this one. It has an absolutely enormous coverage area of 2,400 square feet, which should be more than enough for most homes.
These pollutants can accumulate on the filter, reducing its effectiveness over time. By replacing filters promptly, homeowners can ensure that their air purifiers will continue to trap and remove airborne particles. Unlike room air purifiers which are designed to cover individual spaces, whole house air purifiers are connected to your existing heating, ventilation, and air conditioning (HVAC) systems. They provide additional protection from air pollutants for your entire home 24 hours a day, in areas up to thousands of square feet in size. Furthermore, the added filters from a whole house air purifier makes your HVAC system much more efficient at blocking out air pollutants. The real test of each air purifier was its effectiveness at purifying the air.
This air purifier from Honeywell, another established brand in the home comfort space, uses a pre-filter and True HEPA filter to capture contaminants down to .3 microns. It can perfectly trap up to 98 percent of airborne particles like dust, dirt, and other larger particles. Besides, the device will always be capturing more than 97 percent of airborne particles, which is particularly convenient if you have individuals who have asthma and some other respiratory disorders. Portables can also be noisy because it takes a lot of wind to push air through such a fine filter.
Some older models, particularly ionizers, may produce ozone during operation, which can worsen asthma symptoms. However, a modern air purifier is often an ozone-free whole-house air purifierwith advanced technology that minimizes ozone generation. Overall, the benefits of cleaner air and reduced allergens outweigh any potential drawbacks. Homeowners can expect to experience fresher air, reduced allergens, and a general improvement in indoor air quality relatively quickly after installing a whole-house air purifier.
That said, this is also one of the most quiet models on my list, which would also make it suitable for a bedroom or nursery. While allergies are never fun, this model makes it easy to adapt to changing weather conditions and seasons. For me, a 99.7% filtration percentage or better is the bare minimum I recommend because so many models on the market offer this or better. Keep this in mind when choosing between models if you or anyone in your household cannot move heavier objects. Air purifiers are purchased predominantly by those who suffer from allergies in their home. Depending on the specific allergy and its severity, this can cause all kinds of symptoms, from sneezing, to a blocked nose, to struggling to breathe.
In the North American definition, “true HEPA” means that a filter removes at least 99.97% of airborne particles of a 0.3-micron diameter in a single pass. For reference, human hair usually measures between 20 and 180 microns across. A particle with a 0.3-micron diameter is the toughest size to remove via physical, HEPA-type filtration. So both larger and—counterintuitively—smaller particles are captured more efficiently.
