    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. ☹️

    Classic 400 Air Filter

    My 400 series Hepa Air Filter just keeps on, quietly doing its job. Especially during pollen season.. no huff, no fuss..just restful nights with dependable clean air. THANKS 😊
