your HEPA Filter May Not Be Enough

The Disadvantages of Standard HEPA Filtration

High-Efficiency Particulate Air (HEPA) filtration systems are not a complete solution for appropriately cleaning the air to improve indoor air quality. While it can remove some airborne particulate, standard HEPA filters are not capable of removing some of the most airborne contaminants. While HEPA can remove large air particles such as animal dander, dust, pollen, and more, other common air pollution such as viruses, bacteria, and VOCs remain in the air.

Standard HEPA filtration can filter large debris and some particulate from the air. While its filtration technology can improve air quality and reduce airborne contaminants. Viruses, Bacteria, VOCs, Smoke, and Gases require additional levels of filtration and purification technology to be removed from the air.
