What is the Strongest Air Filter?

In Auto (similar to medium; the Air does not contain a particle counter to adjust to air conditions, but instead asks you to enter the approximate size of your room, after which the machine chooses a fan speed that Molekule deems appropriate), the air performed worse, reducing particles by 0.3 microns at only 18.0% (ambient) and 26.4% (clean). In Silent, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). And in Dark plus Auto, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, it reduced them by 21.3% (ambient) and 18.0% (clean). Interestingly, those numbers closely reflect our results in automatic configuration with the PECO system activated, suggesting the possibility that the Molekule Air depends mainly on its physical prefilter, not its patented PECO mechanism, to remove particles.

When it comes to air purifiers, it's important to know which one is the strongest. By testing 10 models both in the laboratory and at home, we have concluded that the Blueair Blue Pure 211+ Auto is the ultimate air purifier. It has the ability to clean a large room while using minimal power and generating very little noise. It also has an impressive clean air supply rate (CADR) of 360 for smoke, dust and pollen, making it fast and efficient at removing pollutants from the air.

If you're looking for an air purifier on a budget for a small space, then the BlueAir Blue Pure 411 Auto is unbeatable with its automatic mode. It's easy to set up and its operation is also quiet, making it ideal for nighttime use. The Honeywell HPA300 is a bulky device that offers good value for money considering its impressive performance. It has three filters capable of removing most contaminants in a large 465-square-foot room and has an average CADR score of 306 for smoke, dust and pollen.

The most expensive and heaviest air purifier we tested is also one of the best air purifiers: The Blueair Health Protect 7470i. It can clean a room of contaminants efficiently and has two lights in the front that indicate air quality. It's also quite quiet and has a higher energy output compared to others on the list. Finally, if you want to see the impact your air purifier is having in real time, then we recommend the Winix 5500-2.It uses “Plasmawave” technology which creates hydroxyls that easily bind to other molecules to neutralize air faster. It received an average CADR score of 240 as a result. In conclusion, when looking for an air purifier that will help you breathe easier at home, make sure you consider all of these factors: size of room, CADR score, noise level and energy output.

The Blueair Blue Pure 211+ Auto is our top pick for its quality, efficiency and value in one elegant package.
