Compared with the features of other smart air purifiers we’ve looked at, its app, sensors, and programmability are head and shoulders more advanced—almost another species. Although we believe that most people are likely to be happy with a purely analog purifier, if you’re keen on smart appliances, then this model is worth considering. The Levoit Vital 200S is another excellent purifier and is similar to the Coway Mighty in both capability and livability.
How do house air filtration systems work?
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.
Our pick: Coway Airmega AP-1512HH Mighty
In a separate, similar test, we fed the purifiers continuously smoky air by burning incense sticks throughout the test. This test also included the Coway AP-1512HH Mighty, compared against a former large-space pick, the Blueair Blue Pure 211+. In that test, we learned we had to run the machines on high to maintain meaningful purification. Both models achieved this, cutting the particulates by half or more in 50 minutes.
How to Get Better Indoor Air Quality
Despite running it 24/7 for six months, it continued to perform as if it were brand new. The device made such a difference in our old, drafty house and cut down on pet dander in the air, while the humidifier decreased dry skin. 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. If you own pets, you know how much work it takes to keep a tidy home with a furry friend or two sharing your space.
We set four ACH as the minimum for a purifier to be considered adequate for each room size. Based on our years of real-world testing, we know that four ACH ensures rapid and nearly complete cleaning of highly polluted air. When considering a new purifier, we first refer to manufacturer-supplied specs on airflow (usually given as a clean air delivery rate, or CADR). 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). Limit the use of chemical-heavy cleaning products, and stow house paint, glues, and insecticides in a basement or another area that’s away from where you spend most of your time at home.
We’re all about finding space-saving, multi-purpose products, particularly for our little ones! While we have yet to review company testing data on the single-filtration air purity claims, we found the sound machine and nightly aspects easy to use and the filter easy to replace. However, it's not as durable (it weighs in at 1 pound, compared with the 10 to 30 pounds of more solidly built machines), so you'll want to handle it gently, which should be easier to manage in a quiet, low-traffic nursery. Our experts say this Coway is one of the best air purifiers for owners of heavy-shedding or smelly pets. It rivals our top-ranking BlueAir for performance, though it fell short of the winner's circle due to its less-than-average coverage area (361 square feet versus the 540 square feet of the Blue Pure). The Dyson also has one of the most sophisticated onboard air monitors we’ve seen on a purifier.
Levoit Core 300S Air Purifier
Out of all the purifiers on this list, the GT 3000 Whole House Air Purifier is my top choice for the best whole house air cleaner for mold. Overall, if you’re in the market for both an air purifier and humidifier for your home of up to 4200 square feet, I’d recommend the Turonic PH950. I used to believe that air purifiers were just for people who had smelly pets or bad allergies. After living with a roommate who insisted on using one 24/7, though, I now think everyone should have access. Close to $1,000 is a lot to spend on an air purifier, especially if you need multiple units throughout the home.
The Best Air Purifier
They require professional installation because the large filter holder must be plumbed into the ductwork. The price, including installation, ranges from $400 to $600; you’ll need to replace the $40-to-$60 filters every year. Picture a stack of furnace filters about 8 inches thick and you get the idea of an extended media filter. These boxy units contain an accordionlike pile of filtration media, which makes them more effective than regular fiberglass filters. The MERV standard is used mainly to measure the performance of filters meant for forced-air HVAC systems.
How to Shop for Replacement Air Filters
The industry standard for an HVAC filter’s performance is measured according to the MERV scale (Minimum Efficiency Reporting Value—rolls off the tongue!), from MERV 1 through MERV 16. Some sources have claimed that the scale reaches MERV 20, but the testing standard has been updated to clarify that MERV 16 is the maximum. Once the air quality gets as bad as we need it to be for our test, we turn on the air circulation in the room and use a particle analyzer to measure how quickly the filter reduces the particle count. We also monitor how much each filter restricts airflow, using a differential pressure transducer installed across the air filter. You should expect to replace your filter every three to 12 months of use, depending on the size of the filter. Extended filters are made of high-efficient filter paper pleated in an accordion-style frame.
(You can read about the saga in our reports from February and June 2020; the Air was then known as the MH1.) That year we also tested a Molekule Air Mini and judged it to be similarly poor. For optimal performance, vacuum, wipe down, or rinse off the prefilter (it looks like a window screen or plastic netting) every month or so. The prefilter catches larger particles, such as pet hair, and keeping it clean helps the HEPA filter work unimpeded on fine particles. We appreciated some practical and user-friendly features we wouldn’t expect at this price. One version adds Alexa compatibility for remote control and monitoring, although this feature bumps the price up by a bit.
According to the Environmental Protection Agency, the air indoors where we spend as much as 90 percent of our time can be more polluted than even city smog. If you currently have 1-inch filters, you could consider upgrading your system to accommodate 4-inch filters. Your HVAC pro would install a small cabinet next to your furnace or air handler (on the air-intake side) to hold the thicker filter. Once you’ve found each filter, make sure it’s the proper size, measured in inches of length, width, and depth (or thickness). If there are gaps around the sides or it doesn’t line up with any gaskets, it might be the wrong size.

The GermGuardian AC5900WCA was a star performer in our 2019 test, but we also found it to be much louder than the top-pick Coway Mighty, measuring 47 decibels versus 39, on its quiet/medium setting. And the quality of the sound was rough and whooshy, versus the Mighty’s steady white noise. The Medify MA-40 performs similarly to the top-pick Coway AP-1512HH Mighty, but it’s much louder, at 52 decibels (above our 50-decibel definition of “quiet”) on its medium setting and 42 on low. The Coway measured 39 decibels and 31 decibels (nearly inaudible), respectively. The Coway Airmega 150 is the first small-space machine from that company. It’s sharp-looking, with a clean rectangular form and a muted, matte finish available in several colors.
This purifier is terrific overall, but it has minor shortcomings, including a stark look, no display shutoff, and slightly elevated electrical use. It affects our lungs, blood circulation, heart, and overall physical health. But it’s possible that the air inside your home is dirtier than you think. According to the Environmental Protection Agency, the concentration of certain pollutants is often two to five times higher indoors than outdoors.
There's even a handle on top to help you carry it from place to place. The size is the biggest downside, but it's also worth noting that we were unable to figure out how to set up the app due to lacking instructions. That said, operating it manually worked well for us as the machine itself is pretty user-friendly.
After running for just 10 minutes, the Levoit Core 400S Air Purifier not only detected poor air quality levels but also made the air even cleaner than it had been prior to the test. Manufacturers typically base their room-size recommendations (and CADR ratings) on tests with the machines set on high. Purifiers rated for larger spaces can operate on lower, quieter speeds. Smoke particles are right in the 0.3-micron size range—the hardest size to capture—that’s used as the HEPA test standard.
The Levoit Core 300S air purifier aced our lab tests when it came to removing smoky incense from the test environment, reducing PM 2.5 levels to a good range, and eliminating particles in the air within 30 minutes. One of our favorite aspects of this device is the detailed information it gathers and displays within the connected app. You'll be able to see the specific air quality at any time, assess how your room's air has improved or declined across several months, set up times for the purifier to run, and more.
