12-Pack White Floss Pads for Fine Filtration: These floss pads help filter out fine particles and make water crystal clear. Due to vacuum-sealed packaging, they may appear thinner (approx. 1 cm thick), but this does not affect filtration performance. For stronger filtration, you can use two pads at once.
