HEPA filters are good, ActiveHepa+ Plus is BETTER.
If you were only concerned with a little less dusting and vacuuming, any hepa filter will do. When you are concerned with Mold, MycoToxins, Viruses, VOC chemicals, and more....ONLY the ActiveHepa+PLUS will do.
Covering up to 575 square feet, It's the only system designed from the ground up to incorporate a combination of technologies that both reactively capture contaminants and proactively destroy biological contaminants. That includes inside the system, on and within the filter, as well as leaving the system on a proactive mission, to destroy biologicals and VOC chemicals in the Air and on Surfaces.
It has also proven to inactivate 99.98% of SARS-CoV-2 from the air. Allergies a concern? Pollen, pet dander, and odors are but just a few of the many contaminants and allergens that are easily handled by the ActiveHepa+PLUS.
