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!

Such an improvement
We had waited quite awhile to change the filter and when we did, it made a huge difference. I put it one a subscription and now we won't let it get this bad again.
