Blueair Blue Pure 311 Auto Replacement Filter, 2 Pack

The Premium Blue Pure 311 auto replacement filters are compatible with the Blueair Blue Pure 311 auto air purifier, which measures 20.5 inches. It's important to note that these filters are not suitable for the 311 non-auto or 411 models, so ensure that your air purifier is the Blueair Blue Pure 311 auto before purchasing.

The 311 auto replacement filters feature a high-efficiency 2-in-1 filtration system. The Particle Filter is capable of capturing up to 99.97% of airborne particles, such as smoke and pet dander. The Activated Carbon Filter effectively removes household odors from pets, smoking, cooking, and VOCs.

Designed exclusively for the Blueair Blue Pure 311 auto air purifiers, our 311 filter boasts a 360-degree air intake and up to 4 times the filter surface area of the Genuine Blue Pure 311 auto. This filter has been rigorously tested for compatibility and service life, and it is recommended to replace it every 6 months when used 24 hours a day to maintain peak performance.

The 311 filter is designed with silent technology, delivering high-quality, durable, and long-lasting replacements. The collapsible design allows the filter to last longer, and the combination of a high-quality 311 true HEPA replacement filter, electrostatic filtration, and optimized airflow and performance over time results in a faster and quieter cleaning effect compared to traditional HEPA filtration.

The package includes 2 packs of compatible Blueair replacement filters for the 311 auto air purifier, presented in a neutral white box. This is a cost-effective investment, and we value customer service and satisfaction. If you encounter any issues with the filter fitting your air purifier, please contact us through our Amazon home page.
