    Pollen-Free

    EXCELLENT Filters ..... Especially for POLLEN. I live in a Forest in Rural North Florida where PINE POLLEN is so Abundant even my roof gets tainted Yellow-Green from late February through March annually. Additionally, during the Summers they filter out all the Grass and Weed Pollens. These 400 Series Filters are GREAT and keep my indoor air POLLEN-Free ..... LOVE 'Em!
