When it comes to air purification, HEPA technology is the most effective tool for removing impurities from the air. However, there are several other technologies that air purifiers use to reduce indoor pollution, some of which can even be harmful to health. For example, the Molekule Air purifier has three settings: Auto, Silent, and Dark Plus Auto. In Auto mode, the air performed worse than expected, reducing particles by 0.3 microns at only 18.0% (ambient) and 26.4% (clean).
In Silent mode, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). And in Dark Plus Auto mode, 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). These results suggest that the Molekule Air mainly depends on its physical prefilter, not its patented PECO mechanism, to remove particles. The unit can also be synchronized with voice assistants and is equipped with an automatic mode, which automatically adjusts fan speed to ensure energy conservation and clean air.
In the North American definition, “true HEPA” means that a filter removes at least 99.97% of airborne particles of 0.3 microns in diameter in a single pass. The Field Controls patented Pro-cell catalytic grid also transforms odors and VOCs into fresh, breathable air. When it comes to air purification, it's important to consider your health needs and the sources of air pollution in your home. Having your own air purifier is a must if you want a home that's easy to breathe during the dry summer months.
Purifiers work best in an adjoining space; if you want to clean the air in both the living room and bedroom, for example, it's best to buy a purifier for each room or move a single purifier with you.
