Are you in search of the best air purifier for large rooms? Look no further than the Coway Airmega AP-1512HH Mighty. This exceptional, efficient, and affordable air purifier is a finalist in our tests. We have tested more than 50 air purifiers over the past nine years and our measurements have shown that the Coway Airmega AP-1512HH Mighty is the best of them all. It's powerful enough to use in a large room, quiet enough to sleep nearby, designed to last for years, and economical enough to be installed in multiple rooms.
The Coway Airmega 200M is practically identical to Coway's Airmega AP-1512HH Mighty in every important way. They are equivalent in noise and performance measurements, their filters are interchangeable and their similar controls allow the lights on the screen to be turned off. The 200M has a square rather than a round grille, but that's the only important physical difference. If you prefer the look of the 200M or find it at a better price, we recommend it.
The Levoit Vital 200S matched the Coway Airmega AP-1512HH Mighty in performance tests, and both are very similar in terms of energy efficiency, noise emission, and ability to turn off the screen while maintaining the chosen fan configuration. However, the Vital 200S is a new version (January 2020), so 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 setting them to low or medium temperature to create and maintain clean air in the home. After burning 15 wooden matches (to create an initial heavy 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, followed by two at medium temperature.
The presenter places the particle counter directly in front of the filter, almost touching it with the sensor, and observes that practically no particles pass through. These machines are fairly easy to live with, but for the full story on how to set up an air purifier, read our article on this topic. Homer recommends that you read the instruction manual for your air purifier for specific location information. However, because it is a smaller device than air purifiers for large rooms, it may cost less to operate than a larger unit.
While the Airmega 250 doesn't have the same smart capabilities as the Airmega iCons, it's still an attractive design that easily purifies a larger room. For starters, its neutral finish makes it look more like a retro radio than an air purifier, so it can be easily integrated into any space in your home. It doesn't have a way to show an exact air quality reading and it doesn't offer a connection to an app for detailed information. We use a decibel meter to measure the noise levels of each air purifier in its lowest and highest operating modes. Newer air purifier models may include UV lights, which work as a sterilization function to eliminate bacteria that may be in the air.
To clean the outside of the air purifier, Homer recommends using a microfiber towel slightly dampened with your favorite all-purpose cleaner. If you suffer from allergies or are simply concerned about air quality in your home, a HEPA air purifier can help. Investing in one of these devices can help reduce airborne allergens such as dust mites, pet dander, pollen, mold spores, and other pollutants that can cause health problems.
