When it comes to air quality, it's essential to choose the right filter for your needs. After testing more than 50 air purifiers over the past nine years, we have determined that the Coway Airmega AP-1512HH Mighty is the best of them. It is powerful enough to be used in a large room, quiet enough to be placed close to where you sleep, designed to last for years, and economical enough to be placed in multiple rooms. The Coway Airmega 200M is virtually identical to the Coway Airmega AP-1512HH Mighty in every important way.
They are equivalent in terms of noise and performance, their filters are interchangeable, and their similar controls make it possible to turn off the lights on the screen. The only major physical difference between them is that the 200M has a square rather than a round grille. If you prefer the look of the 200M or find it at a better price, we recommend it. The Levoit Vital 200S also matched the Coway Airmega AP-1512HH Mighty in performance tests.
Both are very similar in terms of energy efficiency, noise emission, and the ability to turn off the screen while maintaining the fan setting you choose. However, since the Vital 200S is a new version (January 2012), we haven't had time to test it in the long term yet. In conditions where air quality is poor, such as when an area is affected by a nearby wildfire, we recommend running air purifiers at a high temperature for one hour and then running them in a quiet environment or medium to create and maintain clean air in the home. After burning 15 wooden matches (to create a large initial load of fine smoke particles), we tested this method with the Coway Airmega AP-1512HH Mighty and the Airmega 400 for three hours, one hour at high temperature and two at medium temperature.
The similar Blue Pure 211+ Auto is slightly more powerful (not in a way that can make a significant difference), but it's also more energy efficient due to its new motor and filter, and adds an automatic adjustment that adjusts fan speed to changing air quality conditions. These filters may not be suitable for most home air conditioning systems because their high resistance to airflow can affect heating, ventilation and air conditioning performance. When it comes time to replace your filters, it's easy: remove the plastic bag that they come in, put them back in the machine and that's it. But if there's an air quality emergency, for example, a regional wildfire that causes a shortage of purifier supplies, it's worth trying.
Molekule doesn't share the real numbers, but assuming that the so-called “triple air flow” refers to the 90 cubic feet per minute of the original Air, the Air Pro's maximum air flow would be about 270 cfm, slightly higher than that of the Coway AP-1512HH Mighty, one of the most popular models. Over time, they deflect or bounce off a filter fiber, after which (once again) they adhere to a process called diffusion. The Coway Airmega 240 has no unique abilities; it's for those looking for an attractive, high-performance air purifier at a good price. It's easy to forget about replacing purifier filters occasionally so set a reminder on your calendar.
A year later when those same filters far exceeded the recommended six-month replacement schedule, the numbers barely declined reaching 99.1% and 98.0%, respectively. The Air Pro consumes a lot of energy consuming 27 watts at a speed three times more than what Coway consumes at average speed. This means it's optimized for larger airborne particles such as pollen and mold spores rather than for very fine particles like wildfire smoke (such as HEPA filters). In conclusion, when looking for an air filter for clean air quality, we recommend considering either Coway Airmega AP-1512HH Mighty or Levoit Vital 200S as they both offer excellent performance and energy efficiency.
If you're looking for an attractive filter at an affordable price then Coway Airmega 240 is worth considering as well.
