Blueair Air Purifiers for Large Rooms - Blue Pure 211i Max

The Blue Pure 211i+ Max HEPASilent™ smart air purifier stands out for its impressive efficiency, managing to cleanse spaces of up to 1,524 square feet in just 30 minutes or tackling 635 square feet in approximately 12.5 minutes at high speed. Recognized for its adherence to safety standards, this air purifier has been independently evaluated and third-party tested within the AHAM Verifide® Program for air cleaners. This ensures a Clean Air Delivery Rate (CADR) of 410, effectively targeting fine smoke particles, dust, and pollen.

One notable feature of this air purifier is its proprietary RealTrack algorithm, which measures fan speed, usage time, and pollution levels to assess the filter's cleanliness based on actual use. It provides a more precise indication of when the filter needs replacing—typically within 9 months. For peak performance, opt for the genuine Blueair Blue Pure F2MAX replacement filter (ASIN: B08KPHRLXR).

A unique selling point of Blueair is its customizable, washable fabric pre-filters. These air purifiers are inspired by contemporary Scandinavian design aesthetics, offering a Stockholm Fog pre-filter, while additional colors such as Limestone, Moss, and Sand are available for separate purchase. Comparing pollen CADRs on high fan speed between models like Blue Pure 411a Max and 411i Max versus Blue 411 Auto demonstrates variance among other units. Keep in mind that the AHAM certification values might differ from its claimed rating.

When it comes to noise levels, the measurements indicate a dB(A) difference in acoustic power. Notably, when similar CADR ratings were assessed, Blueair models that incorporate mechanical and electrostatic filtration produced less noise and consumed less energy compared to models solely featuring H13 HEPA mechanical filtration. Testing has shown the ability to remove a minimum of 99.9% of notable pathogens, including S. aureus, K. pneumoniae, and significant viruses like H1N1, within a 30m³ room setting over 90 minutes.

Introducing the latest in the Blueair air purifier line, the Pure Max series features enhanced HEPASilent performance, which now achieves cleaning speeds that are up to 83% faster while operating at 50% less noise than previous models.

Designed for effective and tranquil operation, the Quiet Mark certified device operates at noise levels between 23-53 dB, efficiently cleansing areas of up to 3,048 square feet in 60 minutes. For quicker clean-up, it can handle 1,524 square feet in 30 minutes and 635 square feet in just 12.5 minutes on high speed.

The HEPASilent dual filtration technology within the device ensures that clean air is distributed faster while maintaining lower noise levels and reduced energy consumption when compared to conventional HEPA filtration systems. It effectively captures a minimum of 99.97% of ultrafine airborne particles—including viruses and smoke down to 0.1 microns—and also effectively mitigates allergens such as pet dander, pollen, and mold, alongside a carbon filter that traps light household odors from pets, cooking, and smoking.

In terms of smart features, the Blueair smart air purifier supports app-based scheduling, air quality monitoring, Clean Air ETA notifications, geofencing for welcome home alerts, and RealTrack technology for accurate filter tracking over 6-9 months. Additionally, it integrates with Alexa for effortless voice control.
