فلتر أولي FiberCatch لـ 539AS/530S أبيض/فضي/أسود/ضوء النجوم

Cut the shipping cost from my mind once I saw how perfectly the pre-filter fit my unit—snapped into place without any fuss. The white matches the existing housing so well it looks like it came with the machine. Glad I grabbed this to extend the life of my main filter.

Took a gamble on the color match for my silver unit and it's spot-on, plus the fit around the intake is snug with no gaps. Dust buildup on the outer layer is visible after just a week, which tells me it's doing its job before the main filter. Glad I grabbed it despite the extra shipping cost.

Fits my 530S perfectly and the white matches the unit well, though I wish the $8 shipping was waived. It catches a surprising amount of dust before the main filter, which should help it last longer.
