Read the description for the proper fit, NOT A + MODEL
If you are reading this before placing your order and you own a 331i+, this is the wrong filter. That + is a larger model and this one won’t fit. Don’t be like Bob. Read the description very, very carefully! 😆😁 On another note, I love my Blue Air!

BLUEAIR "311i Max" --or-- "311i+ Max" CONFIRM BY YOUR MODEL LABEL BEFORE ORDERING
BEWARE BUYERS TO GET THE RIGHT FILTER: I bought my BLUEAIR Air Purifier in 2024 and though my Amazon 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 Amazon 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 Amazon size specifications are lacking or nonsensical for many of the filters); https://www.amazon.com/dp/B08KQK5P74?ref=ppx_yo2ov_dt_b_fed_asin_title

Good kitchen air filter
Helps reduce kitchen smoke / general air quality improvement. Moderately improves cat allergies by reducing dander, though not a complete solution
