SHARK HP102 Air Purifier with its nanoseal, antimicrobial Microban HEPA filter mechanically captures micro-pollutants and volatile organic compounds efficiently improving the indoor air quality of a regular room in an aesthetic compact-canister design. In my personal experience, I have seen a significant improvement to my seasonal allergic rhinitis: not only have my sneezing, itching, rhinorrhea symptoms were relieved, I started astonishingly waking up without the constant sinus headaches since utilizing the 12-hour overnight purification process with this "mighty mite" Air Purifier.
