One of the reasons for comparing the Medify MA-25 and Blueair 411 Auto air purifiers is their availability in both the US and EU markets. Additionally, they share a few similar characteristics, such as three fan speeds, impressive performance, similar coverage, and minimalist controls.
These air purifiers cover almost identical room sizes. The Medify MA-25 is suitable for rooms of up to 210 sq. ft. (19.5 m2), while the Blueair 411 Auto is intended for slightly smaller rooms of up to 190 sq. ft. (18 m2). They will clean the air 4.8 times per hour in the recommended room sizes.
Regarding filtration technology, the Blueair 411 Auto has four stages if we count the HEPASilent technology, while the Medify MA-25 has only three. The most significant difference is that the Medify MA-25 features a dual filter with a True HEPA filter and a pellet-based carbon filter. In contrast, the Blueair 411 Auto lacks a True HEPA filter but includes a washable pre-filter.
The Blueair 411 Auto boasts an air quality sensor, air quality indicator, and auto mode features. The Medify MA-25 lacks these features but offers some standard options such as a timer, display lock, and display off.
