The Nispira replacement filter is designed to support a cleaner and more comfortable indoor environment by addressing both gaseous substances and common airborne particles found in everyday household settings. The integrated activated carbon layer is intended to help reduce smoke, pet-related odors, cooking smells, and other household odors, contributing to fresher indoor air during regular use. Manufactured with advanced polypropylene filtration media, the filter is engineered to enhance overall air clarity while capturing a wide range of airborne particles commonly present in residential spaces. Its 360-degree air intake structure and expanded filtration surface—larger than many standard replacement filters—are designed to promote balanced airflow and consistent performance throughout daily operation. Under typical home conditions, the Nispira replacement filter is designed to provide effective use for approximately six months to one year, depending on air quality conditions and fan usage. For optimal performance, replacement every six months is recommended. This package includes one replacement filter. Approximate filter dimensions are 13.4 × 11 × 11 inches.
