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. It is powerful enough to use in a large room, quiet enough to sleep nearby, designed to last for years, and economical enough to set up in multiple rooms. The Levoit Vital 200S matched the Coway Airmega AP-1512HH Mighty in performance tests, and the two are very similar in terms of energy efficiency, noise emission, and the ability to turn off the screen while maintaining the fan configuration of your choice. However, the Vital 200S is a new version (January 2012), so we haven't had time to test it in the long term yet.
As an SEO expert, I can confidently say that HEPA air purifiers are great for filtering wildfire smoke from your home air. We have put our barbs in several homes, often over years, to assess their performance in different environments, how durable they are against noisy children and other sources of harm, and the positive aspects (or annoyances) that are revealed as time goes on. 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. To test this method, we burned 15 wooden matches (to create a large initial load of fine smoke particles) and tested it 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 Honeywell InSight HPA5300B, a large-space model, is likely to perform well but after measuring its electricity demands, we ruled it out.
Compared to our choice for large spaces, the Blueair Blue Pure 211+, the Honeywell consumes a lot of energy, consuming 33, 60, 94 and 117 watts in its four speeds (from low to turbo), respectively. The Blue Pure 211+ reaches a maximum of 64 watts and is a slightly more powerful machine in terms of clean air supply rate (CADR).We also like other Blueair products and this one adds cold air to its purification capabilities: it circulates air five times an hour in a 326 square foot room. You may want to place it in a room where you are particularly concerned about air quality or know that there is a higher concentration of air contaminants. CADR stands for clean air supply rate and refers to the volume of air, in cubic feet, that your air purifier can clean per minute. We repeated this same testing process again with an additional set of nine air purifiers and a set of 10 air purifiers a month later.
Many air purifiers have green mode options which monitor air quality and automatically turn off the device once air quality has been adequately improved. However, we found that the Bionaire BAP0041UVWH True HEPA 360-degree air purifier offered the perfect balance between effective air purification and thoughtful integrated functions. This is particularly true if you don't open or can't open the windows to let fresh air circulate or if the outside air isn't the coolest from the start as can be the case during allergy or wildfire season. If you try this trick, carefully seal the filter around its entire perimeter with strong transparent packing tape; any gap would have allowed unfiltered air to pass through just like in specialized air purifiers. In addition to a HEPA filter, the Air Pro and the Mini+ use Molekule's patented PECO technology which not only captures contaminants such as smoke bacteria and viruses like HEPA filters but also destroys them through a UV-based reaction. For example homes with pets or greater exposure to VOCs may need to run their air purifiers longer or more frequently.
Newer models of air purifiers may have UV lights which work as a sterilization function to eliminate bacteria that may be in the air. After extensive testing over nine years by our team of experts, we can confidently say that Coway Airmega AP-1512HH Mighty is one of the best home air filters available on the market today. It offers powerful performance with low energy consumption and noise emission levels that make it suitable for any home environment. The Levoit Vital 200S, although new on the market, has also proven itself as an excellent option for those looking for an efficient yet affordable home filter solution. Additionally, if you're looking for an even more advanced option with additional features such as cold-air circulation or UV sterilization capabilities then you should consider models such as Bionaire BAP0041UVWH True HEPA 360-degree or Molekule's Air Pro/Mini+.
