This 290 x 594mm cardboard-frame panel filter is rated to the F8 standard, a high efficiency grade suited to ducted air conditioning return air applications. It captures fine dust, pollen, mould spores and many fine particulates that lower-grade panel filters let through, helping keep coils, ductwork and downstream components clean while maintaining good airflow through the system.
Built with a rigid cardboard frame and pleated filter media, it is designed as a disposable, drop-in replacement for a half-size panel opening, commonly paired with a second filter to fill a standard 594 x 594mm return air grille or AHU frame. Suited to commercial and higher-care residential installations where improved indoor air quality is a priority, such as offices, retail and multi-residential ducted systems.
For best results, replace regularly as part of routine ducted air conditioning maintenance to protect system performance and indoor air quality.
