Toxic Plastic Smell
I used my air purifier for years 24/7. It is a great machine, very quiet and efficient. I loved it. However, the newer filters have a sickening plastic smell which makes it unusable! I have always bought my filters directly from Blue Air, so they are legit. They even replaced the last filter (due to smell), but the new one stinks just as bad. We couldn’t even stand to use it when our AQI was ~500. I am now stuck with an unusable purifier. Blue Air must have changed suppliers or formula. ☹️

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!
