When it comes to air quality, HEPA H13-H14 filters are the highest level of filtration and are considered medical grade. After testing more than 50 air purifiers over the past nine years, our measurements have shown that the Coway Airmega AP-1512HH Mighty is the best of them all. It is powerful enough for a large room, quiet enough to sleep nearby, designed to last for years, and affordable enough to be installed in several rooms. The Coway Airmega 200M is practically identical to Coway's AP-1512HH Mighty in every important way.
They are equivalent in noise and performance measurements, the filters are interchangeable and the similar controls on both allow the lights on the screen to be turned off. In conditions where air quality is poor, such as when an area is affected by a nearby forest fire, we recommend setting the air purifiers to a high temperature for one hour and then setting them to a low or medium temperature to create and maintain clean air in the house. We tested this method on the Airmega AP-1512HH Mighty and the Airmega 400 from Coway for three hours (one hour at high temperature), followed by two at medium temperature after burning 15 wooden matches to create a large initial load of fine smoke particles. A HEPA filter is the ultimate solution in the world of air filters and far exceeds what a MERV 13 can do. It uses a HEPA H13 filter and an active carbon filter, and it has 10 different power levels, making it very complete and versatile.
They cannot remove airborne particulates, VOCs, or polluting gases, so they are only fully effective when combined with a HEPA filter. If you suffer from allergies or simply have questions about the air quality in your home, a HEPA air purifier can help. Scientific research warns that the type of air filter is critical to its effectiveness, so HEPA remains the reference standard. This means that it is optimized for larger particles suspended in the air, such as pollen and mold spores, and not for very fine particles such as smoke from wildfires. The Bissell MyAir Pro helps trap allergens and dandruff with its HEPA filtration system, and a carbon filter captures odors.
It also includes a prefilter, an activated carbon filter, and a HEPA H13 True filter that captures 99.99 percent of bacteria and mold. The Bionaire BAP0041UVWH True HEPA 360-degree air purifier offers the perfect balance between effective air purification and well-thought-out integrated functions. On the other hand, in HEPA purifiers, a fan extracts particles suspended in the air through a dense, felt-like filter that has billions of small holes of different sizes. It offers a four-stage purification process, with a prefilter, a HEPA filter, an activated carbon filter and a negative ion generator, which produces negative ions that help keep the air clean. When it comes to finding the strongest HEPA filter, it's important to consider all of these factors. The Coway Airmega AP-1512HH Mighty is our top pick for its powerful performance and affordability.
The Bionaire BAP0041UVWH True HEPA 360-degree air purifier is also an excellent choice for its four-stage purification process and integrated functions.
