Review: Quality filter! Busts ANY KIND of odor!
Review: BEWARE BUYERS TO GET THE RIGHT FILTER: I bought my BLUEAIR Air Purifier in 2024 and though my desertcart Order / Invoice model description is "311i Max", when I look at the actual model number on my appliance it is the model "311i+ Max". If you unscrew the top fan assembly head from your air purifier it will show you which model you have on the label. Most folks probably did what I did and ordered based on my desertcart order description of "311i Max" which is a filter that is about 2-inches too short in height. For the "311i+ Max" you will want this filter, or comparable (which is the BLUEAIR Smoke block filter) (and it DOES NOT HELP that the desertcart size specifications are lacking or nonsensical for many of the filters); https://www.desertcart.com/dp/B08KQK5P74?ref=ppx_yo2ov_dt_b_fed_asin_title
