This 594 x 594mm cardboard-frame panel filter is rated to the F6 standard, a medium-fine efficiency grade suited to ducted air conditioning return air applications. It captures fine dust, pollen and general airborne particulate, in addition to the coarser debris caught by lower-grade filters, 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 standard full-size AHU/return-air panel opening. Suited to residential and commercial ducted systems where a step up in air quality is wanted without moving to a high-efficiency (HEPA-style) filter.
For best results, replace regularly as part of routine ducted air conditioning maintenance to protect system performance and indoor air quality.
