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 ### ⭐⭐⭐⭐⭐ Great purchase! *by on Reviewed in the United States 10 January 2025* The original filter seemed to clean the air but didn't do great at removing odors. I chose to give this filter a try just to see if it would make a difference. It made a complete difference! The air was completely fresh and odorless. Online there is barely any reviews or information on any of the filters and the differences they make.. From what I gathered off google and reddit basically theres the standard particle and carbon filter, a smoke block filter with extra added carbon to capture and neutralize odors and gasses, and an allergen filter which is basically the smoke block filter with an additional filter modification that has some coating to catch germs. I don’t know about all that but it definitely made the air smell and feel much fresher than the one it came with. My unit came in the box without any sort of plastic covering on the filter so that could also have caused the filter to not perform as expected. I recommend purchasing this filter, it’s a little pricey but definitely increases the overall performance of the air purifier drastically. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/683775847-blue-pure-311i-max-series-allergenblock-filter-genuine-replacement-filter](https://www.desertcart.com.ar/products/683775847-blue-pure-311i-max-series-allergenblock-filter-genuine-replacement-filter) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-07-25*
