When it comes to air purifiers, the Blueair Blue Pure 211+ Auto stands out as a top contender, especially for those battling allergies. This review delves into the various aspects of the Blueair Blue Pure 211+ Auto, from its filtration efficiency to its ease of use, maintenance, and more. Whether you're looking to combat allergens, smoke, or just improve your indoor air quality, this review will help you decide if this is the right air purifier for you.

Filtration Efficiency

The Blueair Blue Pure 211+ Auto boasts a HEPASilent dual filtration system, which combines mechanical and electrostatic filtration. This unique combination allows the purifier to deliver up to 45% faster cleaning and up to 67% less noise than traditional HEPA filtration alone. The device is capable of removing 99.97% of airborne particles down to 0.1 microns, including dust, pollen, pet dander, mold spores, and even bacteria and viruses.

One of the standout features is its ability to remove odors and particles, making it ideal for smoke and smog, particularly during wildfire season. The carbon filter effectively traps light household odors from smoking, pets, and cooking, ensuring your home smells fresh and clean.

Noise Level

Noise level is a critical factor when choosing an air purifier, especially if you plan to use it in a bedroom or living room. The Blueair Blue Pure 211+ Auto excels in this area, operating at a whisper-quiet 23 dB on its lowest setting. This is quieter than a whisper, making it perfect for nighttime use without disturbing your sleep.

The auto mode feature adjusts the fan speed based on the air quality, ensuring optimal performance while maintaining a low noise level. Even at higher speeds, the noise remains manageable, allowing you to enjoy clean air without the constant hum of a loud machine.

Portability

Weighing in at just 7.33 pounds and with dimensions of 13"D x 13"W x 20"H, the Blueair Blue Pure 211+ Auto is relatively portable for an air purifier of its capacity. It can easily be moved from room to room, making it versatile for use in different areas of your home. However, it is designed primarily for larger rooms, so its portability is best utilized within a single floor or area.

Ease of Use

The Blueair Blue Pure 211+ Auto is designed with user convenience in mind. The one-touch auto mode uses a particle sensor to monitor pollutant levels and adjusts the fan speed accordingly. The LED indicator displays the air quality status in real-time, showing blue for excellent, orange for moderate, and red for polluted air. This intuitive design makes it easy for anyone to use, even without prior experience with air purifiers.

The control method is straightforward, utilizing button controls that are easy to understand and operate. Additionally, the device comes fully assembled, so you can start using it right out of the box.

Maintenance

Maintenance is a crucial aspect of owning an air purifier, and the Blueair Blue Pure 211+ Auto makes it relatively hassle-free. The pre-filter is washable, which helps extend the life of the main filter and reduces the frequency of replacements. The main filter, a combination of particle and carbon filters, should be replaced every six months to ensure optimal performance.

One potential downside is the cost and availability of replacement filters. While Blueair recommends using genuine filters for optimal performance, these can be more expensive and harder to find compared to generic alternatives. However, the high efficiency and performance of the Blueair filters justify the cost for many users.

Special Features

Auto Mode and Air Quality Indicator

The auto mode is a standout feature, automatically adjusting the fan speed based on real-time air quality readings. This ensures that the air purifier operates efficiently without wasting energy. The LED air quality indicator provides immediate feedback on the air quality, making it easy to see how well the purifier is working.

Energy Efficiency

The Blueair Blue Pure 211+ Auto is ENERGY STAR rated, consuming less energy (4W on low) than an LED lightbulb. This makes it not only effective but also kind to your wallet and the planet. The low energy consumption means you can run the purifier continuously without worrying about a significant increase in your electricity bill.

Safety and Certifications

Safety is a top priority for Blueair, and the Blue Pure 211+ Auto meets several important standards. It is AHAM Verifide for CADR (Clean Air Delivery Rate), CARB certified for ozone safety, and has been tested and verified to produce zero ozone (<5 ppb). These certifications provide peace of mind that the air purifier is both effective and safe to use.
