Blueair Blue Pure 121 Air Purifier Replacement Filters (2-Pack)

The HEPA+Activated Carbon Filter offers a double-layer filtration system that effectively removes annoying household odors, chemicals, and gases, as well as 99.97% of airborne particles as small as 0.1 μm, such as pollen, dust, and pet dander. The 121 replacement filter utilizes a new and upgraded carbon spray technology, resulting in an even distribution of the toner, which enhances the filter's ability to absorb odors more effectively and allows for easy air flow.

Installing the replacement filter is a straightforward process. Simply unplug the air purifier, gently press the release buttons on either side until a click is heard, and lift off the top. Remove the old filter and replace it with a new one. Reattach the top portion of the air purifier, and it will click into place when properly secured. This collapsible design makes it easy to store and replace the filter as needed, which helps extend the life of the air purifier and maintain the purity of the air for an extended period.

The 121 Replacement Filter, 311 Replacement Filter, and 121 Pre-filter are all available for purchase, with customer reviews ranging from 4.2 to 4.5 out of 5 stars. These replacement filters are designed to be compatible with the Blueair Blue Pure 121 and 311 Air Purifiers, ensuring superior performance and maintaining the integrity of the product's warranty.

The new activated carbon distribution technology employed in these filters provides more uniform absorption of household odors, fumes, chemicals, and volatile organic compounds (VOCs), making the filtration process more effective and efficient. The filter structure is designed to trap even the smallest particles while resisting clogging, which helps maintain maximum airflow and results in quieter and more energy-efficient air purifiers.

The manufacturer is committed to customer satisfaction, and they encourage customers to reach out with any problems they encounter during use. The company promises to provide a satisfactory response within 24 hours, further emphasizing their dedication to ensuring a positive user experience.
