فلتر مسبق FiberCatch لـ 539AS/530S أبيض

After a month of use, the white pre-filter is already noticeably darker, which means it's catching all the dust my old one missed. Installation took maybe 30 seconds with no tools needed.

This pre-filter popped right into place on my 539AS without any struggle, and the white color matches perfectly. I've noticed the main filter is staying noticeably cleaner after a week of use, which is exactly what I was hoping for.

Wasn't sure a third-party filter would fit right, but it clicks into place on my 530S just like the original. The white mesh catches a surprising amount of dust and pet hair before it ever reaches the main filter.
