In this review the Leemone 411i Max & 411a Max SmokeBlock replacement filters are assessed for owners of the Blue Pure 411i Max and 411a Max air purifiers who need reliable particle and odor removal. The bottom line: these two-pack replacements deliver a near-OEM fit and strong filtration for common indoor pollutants, making them a practical, value-oriented choice for households with pets, cooking fumes, or light smoke. The reviewer found installation straightforward and performance consistent with the stated ability to remove very small particles.

Key Features

• Perfect fit: Designed exclusively for Blue Pure 411i Max and 411a Max units, the filters install without modification and maintain proper airflow.
• High particle capture: The SmokeBlock element cleans up to 99.97% of particles as small as 0.1 microns, helping reduce pet dander, pollen, and fine dust.
• Activated carbon layer: Integrated carbon targets household odors from smoking, pets, and cooking fumes for noticeably fresher air.

Who It's For

These filters are aimed at users of the Blue Pure 411i Max and 411a Max who want an affordable, compatible SmokeBlock replacement that captures fine particles and reduces common household odors. They suit households with pets, smokers, or regular cooking where ongoing odor control and particulate removal matter.

Shoppers using older or different Blueair models such as 411, 411+ or 411 Auto should not buy this model because it is not compatible. Also, those needing industrial-grade smoke or allergen control beyond typical home use may want to consider specialized HEPA/medical-grade options instead.
